Agriculture Secretary Tom Vilsack today announced $100 million in financial assistance to acquire permanent easements from eligible landowners in four counties and assist with wetland restoration on nearly 24,000 acres of agricultural land in the Northern Everglades Watershed.

The wetland restoration will reduce the amount of surface water leaving the land, slowing water runoff and the concentration of nutrients entering the public water management system and ultimately Lake Okeechobee and the Everglades.

This is the largest amount of funding Florida has ever received for projects in the same watershed through the Wetlands Reserve Program (WRP) in a single year.

“Protecting and restoring the Northern Everglades is critical not just to Floridians, but to all Americans,” said Vilsack.

“Today’s announcement demonstrates the Obama Administration’s strong commitment to conserve our national treasures, enhance the quality and quantity of our water, and secure the economic opportunities afforded by a healthy Everglades ecosystem.

“This announcement would not be possible without our local conservation partners and our relationship with private landowners who play a critical role in restoring wetlands and protecting wildlife in this unique habitat.”

Vilsack also participated in a signing ceremony with A.J. Suarez of Hendry County Nursery Farms — a landowner who will benefit from the funding.

Suarez signed an agreement with USDA to start the process to acquire the easement rights to 3,782 acres.

After the signing ceremony, Vilsack toured the 550-acre Winding Waters Natural Area, a site restored with $1.5 million from WRP in 2007. The nature area, owned by Palm Beach County, is home to bird species such as little blue heron, snowy egret and great egret, white ibis and Florida sandhill crane.

It also contains large areas of pine flatwoods, Cyprus forests, freshwater marshes and wet prairies.

Under WRP, landowners sell development rights to land and place it in a conservation easement that permanently maintains that land as agriculture and open space.

South Florida Farmers Achieve Record Year in Water Quality Success

August 11, 2011 by admin  
Filed under Protecting Habitats, Water Quality

/PRNewswire/ — Farmers in the Everglades Agricultural Area (EAA), south of Lake Okeechobee, achieved a record-setting 79 percent phosphorus reduction in the water leaving the farming region — more than three times less phosphorus than the state requirement.

The South Florida Water Management District, the agency tasked with Everglades restoration, announced today that the EAA’s on-farm Best Management Practices (BMPs), developed by university scientists in collaboration with farmers, are a resounding success. The District praised EAA farmers for being proactive and often implementing more BMPs than what is required.

“We’re proud of farmers’ accomplishments cleaning water, with an average phosphorus reduction of 55 percent over the last 16 years,” said Barbara Miedema, vice president of the Sugar Cane Growers Cooperative. “When the BMP program was first envisioned in 1991, no one imagined it would be this effective over the long term. It’s an example of the kind of success that can be achieved in partnership with scientists and farmers, who roll up their sleeves to get the job done.”

In addition to improving water quality using high-tech sustainable practices, more than $200 million has been paid by farmers for the construction of Stormwater Treatment Areas (STAs) to further clean water. Built on 60,000 acres of former farmland, the STAs have reduced phosphorus to the Everglades Protection Area by an additional 1,470 metric tons. That’s in addition to the 2,400 metric tons of phosphorus removed by farmers.

“Along with being stable economic drivers and job providers for our state and county, farmers have a long track record of supporting and implementing Everglades restoration,” said Gaston Cantens, vice president of Florida Crystals Corporation. “Today’s record-breaking results are another example of the proven success of our sustainable practices and demonstrate the significant role our farms continue to play in protecting and preserving the Everglades ecosystem, as the design was intended.”

May 18 - San Diego Mayor Limits City’s Use of Single-Use Plastic Water Bottles, Plastic Foam Products

Attention: open in a new window.

San Diego Coastkeeper applauds the action, which stems from the organization’s 2009 proposal

SAN DIEGO, CA-May 18, 2011- Today San Diego Mayor Jerry Sanders’ office and the Environmental Services Division announced a series of administrative regulations to limit the City’s purchase of single-use plastic water bottles and plastic foam products (often inappropriately referred to as Styrofoam™). San Diego Coastkeeper, the region’s largest environmental organization protecting inland and coastal waters, applauds the mayor’s action, which stems from the organization’s 2009 proposal urging the City Council to take the steps. The new guidelines, announced today to the San Diego City Council Natural Resources and Culture Committee (NRC) and effective on January 1, 2012, will reduce the City’s environmental impacts, potentially save money, reinforce confidence in the city’s municipal water system and set a precedent for other cities in the region.

The item was brought to the Committee after a December 2010 request from former Chair Donna Frye.  Under the strong mayor-strong council form of government, the administrative regulation does not need Council approval.  However, showing support for the ideas within the regulation, the NRC requested that the Mayor’s office report on the implementation of these policies at the November 16 NRC meeting.

“This will show great leadership to the residents of San Diego,” said City Council Member David Alvarez, who chairs NRC. He also noted that the City is the first in San Diego County to take these initial steps.
Specifically but not inclusively, the Mayor’s administrative regulation will:

  • Prohibit the purchase of single-use water bottles and water bottle dispensers with City funds, with the exception of facilities that do not have access to safe tap water to drink
  • Prohibit the purchase of plastic foam food service ware with City funds (referred to as expanded polystyrene, or EPS)
  • Develop standard language for bids that expresses the City’s commitment to eliminating plastic foam in packing materials, using alternative recyclable packing materials when available and/or vendor take back of the packing materials. This includes working with current vendors to reduce plastic foam use.
  • Revise City permit applications; including those for special events, parks and recreation facilities, and water reservoirs and lakes, to prohibit the use of plastic foam food service ware.

“We commend Mayor Sanders for demonstrating environmental leadership and fiscal responsibility with his policy limiting the City’s purchase of single-use plastic water bottles and plastic foam products,” said Alicia Glassco, San Diego Coastkeeper’s education and marine debris manager. “We hope the door will remain open to expand the restriction of plastic foam use beyond City events and that other cities will follow the Mayor’s lead and take similar action.”

The City of San Diego joins 48 California cities that have already committed to reducing plastic foam for environmental reasons and 28 jurisdictions that have limited bottled water purchases to reduce expenses and support public water systems.

“San Francisco canceled its bottled water contracts and saved half a million dollars a year,” said John Stewart, national campaign organizer with Corporate Accountability International. “San Diego will join the ranks of 1,200 cities and five states nationwide that have taken similar steps, saving millions of dollars.”

This step by Mayor Sanders comes on the heels of the statewide Senate Bill 568, which would prohibit the distribution and use of plastic foam containers by food vendors. Currently, the senate floor expects the bill sometime next week. Support organizers identified Senator Juan Vargas as a swing vote on the matter and ask that he take this action as a sign that his constituents are calling for reduced litter and debris.

San Diego Coastkeeper first proposed restricting bottled water and plastic foam at City facilities and events to former City Councilmember Donna Frye in late 2009. Coastkeeper cited beach cleanup data from across the county, which indicates a growing problem of plastic water bottles, plastic bottle caps and pieces of plastic foam littering the environment. In 2010 alone, volunteers removed more than 25,000 pieces of plastic foam, which is lightweight, floats and easily breaks into small pieces making it a challenge for removal from storm drains and the environment.

San Diego Coastkeeper’s website (http://www.sdcoastkeeper.org) hosts more information about beach cleanup data in San Diego County and the harmful effects of marine debris on the environmental, marine mammals and humans.

Dead zones in ocean threaten fish

January 22, 2011 by admin  
Filed under Protecting Habitats

FT. LAUDERDALE, Fla. — With the New Year comes new challenges to fish in our world’s oceans and one of the major concerns is the expansion of hypoxic zones. That’s the scientific name but more recreational anglers are becoming aware of them as “dead zones.”

They are areas in the oceans with low or non-existent oxygen levels which, according to a recently released research study by scientists and fish management experts, are increasing in size while decreasing the habitats of billfish and tuna. In scientific circles this phenomena is called “habitat compression.”

Ellen Peel, president of The Billfish Foundation (TBF) said scientists outfitted 79 sailfish and blue marlin in two strategic areas of the Atlantic with pop-off archival satellite tags which monitored their horizontal and vertical movement patterns.

“Billfish favor abundant habitats of oxygen-rich waters closer to the surface while avoiding waters low in oxygen,” Peel said. The study, composed of scientists from the National Oceanic and Atmospheric Administration (NOAA), the University of Miami Rosenstiel School of Marine and Atmospheric Science, and TBF, found a massive expanding low oxygen zone in the Atlantic Ocean is encroaching upon the fish forcing them into shallower waters where they are more likely to be caught. The research waters included areas off south Florida and the Caribbean (western North Atlantic); and off the coast of West Africa (the eastern tropical Atlantic).

Hypoxic zones occur naturally in areas of the world’s tropical and equatorial seas because of ongoing weather patterns, oceanographic and biological processes. In the current cycle of climate change and accelerated global warming, hypoxic areas are expanding and shoaling closer to the sea surface, and may continue to expand as sea temperatures rise.

“The zone off West Africa,” said Dr. Eric D. Prince, NOAA Fisheries Service research biologist, “encompasses virtually all the equatorial waters in the Atlantic Ocean, is roughly the size of the continental United States and is growing. With the current cycle of climate change and accelerated global warming we expect the size of this zone to increase, further reducing the available habitat for these fishes.”

Oil platform could put critically endangered whales at risk

Oil platform could put critically endangered whales at risk

Sakhalin Energy Investment Company already has two platforms in the area and have previously said that their drilling technology meant that they would not need a third. An official Sakhalin Energy document also acknowledges that having two rather than three platforms “significantly reduces the potential for environmental impact”.

The company plans to conduct a seismic survey which involves shooting loud pulses of noise into the ocean floor later this year to determine where to begin platform construction.

Three seismic surveys conducted around the whale feeding habitat last summer caused severe pressure on the animals as the noise from the surveys can be devastating for species that rely on sound to navigate, communicate and find their food.

Grey whales occur on both sides of the Pacific Ocean. However IUCN classes the critically endangered Western population as separate from the Eastern population, as genetic studies indicate that the two populations probably do not mix.

Only around 130 whales of the critically endangered Western population exist today.

The construction and operation of an additional off-shore platform could have a number of negative effects on the whales, including disrupting feeding behaviours and increasing the chance of fatal ship strikes.

Aleksey Knizhnikov, Oil Gas Environmental Policy Officer for WWF-Russia says on the WWF website: “Just around 30 female western Grey whales of breeding age remain the population is already on the brink of disappearing forever. The loss of even a few breeding females could mean the end for the population.”

During the feeding season the whales must eat enough to maintain themselves for the migration to their breeding grounds. Their primary feeding area, near the proposed platform, is also one of the only places where mother whales can teach their calves to feed on the sea bed.

“We are astonished by the announcement from Sakhalin Energy that it intends to build a third platform,” said Wendy Elliott, Species Programme Manager, WWF-International.

Doug Norlen, Policy Director at Pacific Environment reiterates:”We still do not know how badly the whales were affected by major seismic activity last summer and will not know until the whales return to their feeding grounds again this year and scientists can determine if any are malnourished. It is totally inappropriate for Sakhalin Energy to plan another seismic survey in 2011 before we have the opportunity to examine the health of the animals.”

Topsail beach renourishment project begins - WECT

Filed under Protecting Habitats

Reported by Lindsay Curtin bio | email

PENDER COUNTY, NC (WECT) - Most people go to the beach to have fun without realizing the work it takes to keep it beautiful.

A $7.3 million project is finally underway for the town of Topsail Beach.

Over the next couple months, dredging companies will be pumping 900,000 cubic yards of sand to the beach. The extra sand will provide added protection against beach erosion and home damage in the event of a hurricane.

“It flattens out the beach, stops the wave action and slows the erosion of the beach, so it basically helps protect from beach erosion in hurricanes and offers a higher level of protection for structures,” said Topsail Town Manager Tim Holloman.

No matter how expensive the project might be, most residents agree it is worth it, considering almost all of Topsail Island sits in aFEMA declared flood zone. The project is expected to be finished at the end of March.

Endangered species’ top 10 list: Save these ecosystems

January 6, 2011 by admin  
Filed under Protecting Habitats

Oceana, an international ocean conservation group, yesterday released a new report that identifies vital habitats in need of protection, if key endangered species are to have a chance to survive climate change. According to the Intergovernmental Panel on Climate Change (IPCC), 20 to 30 percent of the world’s species will be at increased risk of extinction if global temperature increases exceed 1.5 to 2.5 C (3 to 5 F) above pre-industrial levels. The climate threats to species include increased disease, diminished reproduction, habitat loss, and declining food supply.

For species that are already struggling on the brink of extinction, global climate change threatens to push them over the edge, said Huta. We certainly need to reduce global warming pollution, but we also need to act now to prioritize and protect some of the most important ecosystems for imperiled wildlife. Endangered species don’t have the luxury of waiting for political leaders to act to slow the pace of climate change.

List of top 10 ecosystems to save for endangered species featured in the report:

1. Arctic sea ice, home to the polar bear, Pacific walrus and at least six species of seal

2. Shallow water coral reefs, home to the critically endangered elkhorn and staghorn corals

3. The Hawaiian Islands, home to more than a dozen imperiled birds, and 319 threatened and endangered plants

4. Southwest deserts, home to numerous imperiled plants, fish and mammals

5. The San Francisco Bay-Delta, home to the imperiled Pacific salmon, Swainsons hawk, tiger salamander and Delta smelt

6. California Sierra Mountains, home to 30 native amphibian species, including the Yellow-legged frog

7. The Snake River Basin, home to four imperiled runs of salmon and steelhead

8. Greater Yellowstone Ecosystem, home to the imperiled Whitebark pine, an important food source for the threatened Grizzly bear and other animals

9. The Gulf Coasts flatlands and wetlands, home to the Piping and Snowy plovers, Mississippi sandhill crane, and numerous species of sea turtles

10. The Greater Everglades, home to 67 threatened and endangered species, including the manatee and the red cockcaded woodpecker

Climate change is no longer a distant threat on the horizon, said Leda Huta, executive director of the Endangered Species Coalition. It has arrived and is threatening ecosystems that we all depend upon, and our endangered species are particularly vulnerable.

Seven additional ecosystems were nominated but did not make the Top 10. They nonetheless contain important habitat for imperiled species. These ecosystems include Glacier National Park, the Jemez Mountains, Sagebrush Steppe, U.S. West Coast, the Maine Woods, the Grasslands of the Great Plains and the Southern Rocky Mountains.

The new report, which includes information about each ecosystem, as well as recommended conservation measures, is available online at www.StopExtinction.org.

Scientists ranked Arctic sea ice and shallow water corals as two of the highest priority ecosystems threatened by climate change in an Endangered Species Coalition report demonstrating the urgency of saving habitat for endangered species. The report, entitled Its Getting Hot Out There: Top 10 Places to Save for Endangered Species in a Warming World was released January 5th, and examines how the changing climate is increasing extinction risk for imperiled fish, plants and wildlife.

Have your say: Is the reality of climate change still in question?

Opening US Areas for Oil More Lucrative Than Taxes, Group Say

January 4, 2011 by admin  
Filed under Protecting Habitats

Opening the eastern Gulf of Mexico and Atlantic Ocean to oil exploration would generate more revenue for the U.S. than increasing taxes on the energy industry, a trade group said.

Offshore production from areas closed to development would generate $149 billion for government through 2025, while higher taxes would cut output and reduce employment and investment, trimming revenue by $128 billion, the American Petroleum Institute said today in a report.

The Obama administration last year excluded the waters west of Florida and the Atlantic coast south of Delaware from
drilling after BP Plcs well ruptured in the Gulf of Mexico. These areas hold about 7.6 billion barrels of oil, according to API, which represents more than 450 energy companies.

Our leaders must pursue a thoughtful, common-sense energy agenda that promotes U.S. job creation, economic growth and energy security, the Washington-based group said in the report. We encourage policy makers to increase energy production.

Among APIs members are the largest U.S. oil companies, Exxon Mobil Corp., Chevron Corp. and ConocoPhillips.

The National Wildlife Federation, based in Reston, Virginia, and the Washington-based Ocean Conservancy said regions such as Floridas Gulf Coast or Alaska have qualities that should preclude them from being exposed to an oil-drilling catastrophe such as BPs spill, which spewed crude for 87 days and closed a third of the Gulf to fishing.

Drill or Import

Our nation will require more oil and natural gas for decades to come, API President Jack Gerard said today at a conference in Washington. A lot of it will come from deep-sea wells. And if it doesn’t come from here, then well import it.

Opening the eastern Gulf, Atlantic coastline, the Rocky Mountains and Alaska to more drilling would create 160,000 jobs by 2030, according to API.

The American people sent a message last November, Gerard said. They want lawmakers focused on an agenda that promotes growth. And they want job creation at the forefront.

API failed to note the growing U.S. supplies of natural gas from shale developments, billionaire oil investor T. Boone Pickens said today in an e-mailed statement. Natural gas should be used to reduce the nations dependence on imported diesel, Pickens said.

This is, after all, a group that includes and represents foreign oil companies, Pickens said about API. No one should be fooled by this report.

API members include London-based BP and the U.S. subsidiary of Saudi Aramco, the worlds largest state-owned oil company.

Climate-Change Rules

The trade group, which also represents oil refineries, said Congress should take a thoughtful and balanced approach to climate-change polices, rather than proceeding with Environmental Protection Agency rules. The EPA began regulating carbon-dioxide pollution from electric power plants and refineries on Jan. 2.

The oil and gas industries spent over $135 million on lobbying and campaign contributions last year, Jeremy Symons, National Wildlife Federation senior vice president for conservation and education, said in an e-mail. Now theyre clearly sending a message to Congress that its time to cash in.

The BP Oil Spill’s Long-Term Threat to Bluefin Tuna

December 25, 2010 by admin  
Filed under Protecting Habitats, Toxic Spills

Bluefin tuna

When BP’s Deepwater Horizon oil spill spewed millions of gallons of crude into the Gulf of Mexico, one of the most pressing questions was how the environmental disaster would affect the area’s other major industry: fishing, and in particular, the highly prized bluefin tuna.

In the short term, Gulf fishing was crippled, as thousands of square miles were immediately closed. But even after some of these areas reopened, scientists and fishermen alike worried about the long-term effect of contamination on the area’s bountiful aquatic life. Recently, evidence has emerged to suggest that the oil spill may have an impact far beyond the Gulf, threatening one of the world’s most lucrative fishing species.

The controversy surrounds dispersants, the chemical compounds that BP (BP) used to break up the spilled oil. Basically a form of detergent, dispersants make it possible for oil to interact with water, transforming huge oil slicks into microscopic droplets that could seemingly disappear into the Gulf. In theory, at least, this would make it easier for bacteria and weather to further break down the oil, allowing it to dissolve into the environment.

Ignoring a Key Issue?

When BP began using dispersants, many environmentalists fretted that the compounds might harm the area’s fragile ecosystem. In response, the U.S. Environmental Protection Agency launched a two-pronged study to measure the toxicity of various dispersants. Their ultimate conclusion was that the eight dispersants tested — including Corexit 9500A, the main compound used in the Gulf — were generally less toxic than crude oil. What’s more, the EPA detected little or no increase in toxicity when dispersants were combined with oil. That is, the action of breaking down an oil slick generally did not add more toxins to the Gulf.

According to Peter Hodson, an aquatic toxicologist at Queen’s University in Kingston, Ontario, the EPA study ignored a key issue. While dispersants don’t increase the toxicity of petroleum, they can vastly increase the chances that a fish will interact with oil, and that the oil’s toxicity will affect sea life.

“After all,” Hodson points out, “Oil toxicity isn’t an issue until fish are exposed to it. Unfortunately, as minuscule dispersed oil droplets combine with water, the volume of the oil spill vastly expands. This can increase the risk to fish by 100- to 1,000-fold.”

Out of Sight, Out of Mind

One of the big problems, Hodson notes, is a matter of perspective. While oil dispersants make a spill disappear from the water’s surface, they don’t actually make it go away. For people, who naturally view a spill from above the surface of the water, it’s easy to see the effect of oil on birds, people and beaches, but harder to see the effect on fishes and other underwater organisms. That effect that may be increased as dispersants cause oil to combine with the water instead of float on the surface.

Hodson emphasizes that “This can lead to a blind approach when assessing risk, a process that is already difficult in an oil spill. If you are convinced that dispersants are not an issue because they aren’t more toxic than oil, then a lot less attention will be paid to what’s under the water, and we’re a lot more likely to endanger aquatic resources.”

This is particularly problematic for the Gulf’s sea life, especially eggs and embryos, which, Hodson says, “can’t move out of the way of oil.” Consequently, they’re likely to absorb dispersed oil and the chemicals that it releases. To make things worse, Hodson continues, “embryos and baby fish have thin skins, which makes them more susceptible to chemical contamination. This can lead to ‘teratogenic effects,’ or deformities.”

Bluefin Tuna in the Crosshairs

For the most part, attention has focused on the oysters and shrimp for which the Gulf is known. However, its waters are also home to a wide variety of sea life, including northern bluefin tuna, one of the most expensive fish species in the world. The tuna, which conservationists claim is on track to become an endangered species, spawns in only two areas: the Mediterranean Sea and the Gulf of Mexico.

While many fish may die because of the contamination, an even bigger problem may be the long-term impact on bluefin breeding. Hodson notes that “petroleum contamination could cause embryos to develop deformities, which can make it impossible for the young fish to grow old enough to reproduce.” This, in turn, could leave a major hole in breeding populations over the next few years.

To make things worse, bluefin tuna is already experiencing major problems. Exceedingly popular for sushi, the price of bluefin has skyrocketed over the past few years: In January 2010, a 510-pound bluefin tuna sold in Tokyo’s fish market for $175,000. With prices like that, fishermen are eager to reel in the fish.

Hammered at Both Ends

Fearing the bluefin’s extinction, the International Commission for the Conservation of Atlantic Tuna set a 2010 quota of 13,500 tons, a 38% drop from 2009. In some regard, however, the ICCAT’s quota is largely irrelevant: Because of poaching and overfishing, the actual annual tuna yield is likely closer to 60,000 tons.

With so much money on the line, the pressure is tremendous to keep the bluefin tuna industry chugging along. Last month, fishing advocates successfully tabled a European Union plan to radically cut quotas aimed at allowing bluefin stocks to recover. Meanwhile, U.N. attempts to scale back or limit the industry have been blocked by several countries, notably Japan, which has lobbied aggressively to keep fishing quotas high.

Unfortunately, it will likely be years before scientists can fully measure the impact of the BP spill on the fish. During the initial cleanup efforts, it was impossible to directly observe the effect of the Deepwater Horizon oil on bluefin tuna embryos, though Hodson emphasizes that the long-term effect will be a decline in breeding stocks.

However, he warns, with overfishing threatening older bluefin tuna and oil contamination threatening embryos, humans are “hammering the bluefin population at both ends,” a process that is likely to lead to a devastating conclusion.

Outside Cancún climate conference, Caribbean Sea testifies to global warming

December 7, 2010 by admin  
Filed under Global Warming, Protecting Habitats

Bayahibe, Dominican Republic

This summers extreme heat may seem like a distant memory as winter approaches the United States.

But the summer that broke heat records across the Northern Hemisphere is still being felt below the surface of the Caribbean Sea: 2010 will likely be one of the most deadly years on record for coral reefs.

If diplomats attending the two-week global climate change talks that opened Monday in Cancn, Mexico, want more evidence of the negative and potentially devastating affects of warming temperatures, they need look no further than the blue sea outside their hotels. Researchers say that throughout the Caribbean coral reefs are bleaching, a condition that occurs when they are under extreme stress due to warmer-than-normal sea temperatures.

The last major bleaching, in 2005, resulted in the death of 40 percent of corals in parts of eastern Caribbean. When full results are in, this year is likely to be worse, scientists said.

When we average out the net bleaching events and severity across the Caribbean basin, 2010 (and more than likely 2011) will go down in the record books as having the most severe bleaching and coral mortality in over 20 years, says Rick MacPherson, conservation programs director of the Coral Reef Alliance (CORAL).

Coral feels heat

Under normal conditions, algae live symbiotically within the coral, giving it color and providing it with a source of food. But under stress, the coral expels the algae, leaving it whitened, or bleached. The longer the coral remains bleached, the more likely it is to die, according to marine biologists.

Following a hot summer the fourth hottest on record for the US, according to the National Oceanic and Atmospheric Administration (NOAA) nearly the entire Caribbean was at risk for bleaching. While some bleaching occurs every year, this year stands out.

Temperatures are high in the Caribbean, and we expect this to continue. This season has the potential to be one of the worst bleaching seasons for some reefs, Mark Eakin, coordinator of NOAAs Coral Reef Watch, said in a statement in late September.

The phenomenon is not confined to the Caribbean. Coral reefs in Southeast Asia and in the Indian Ocean are experiencing their worst bleaching since 1998. Scientists expect similar results for the Great Barrier Reef off the coast of Australia.

Reefs worth $375 billion a year

The environmental and economic impacts are potentially enormous.

Coral covers less than 1 percent of the ocean floor but provides habitat and supports as much as 25 percent of all marine life. Coral reefs are home to more than 1 million aquatic species. And barrier reefs knock down waves before they reach shore, cutting down on the rate of coastal erosion, according to coral reef conservation groups.
