The dead zone is primarily the result of nutrient pollution that stimulates massive blooms of algae. When this algae decomposes, oxygen levels drop below levels needed by many Gulf species to survive or develop normally; scientists refer to low-oxygen conditions as hypoxia.
There are also issues with walls and fences that have already constructed along across 600 scattered miles of the U.S.-Mexico border, blocking approximately 49 species from accessing part of their natural habitat, placing species in danger and resulting in off-balance or destroyed ecosystems.
The nation’s 56 million Latinos are especially vulnerable to the health threats posed by climate change because of where they live, work and lack access to health care, a report released recently by the Natural Resources Defense Council said.
In Florida there are more than 1.3 million alligators and are sharing territory with humans like never before.

Cuba’s coral reefs are among the most pristine in the Caribbean. In new and ongoing collaborations, NOAA and Cuban scientists will compare Cuban reefs with nearby U.S. reefs.
The 35-year-old bird named AC-4 soared out of his open pen earlier this week at a canyon rim inside the Bitter Creek National Wildlife Refuge, in central California’s Kern County. He had been one of just 23 condors left in the world in the 1980s.
Thousands of fish lay dead in what used to be Mountain Meadows reservoir also known as Walker Lake, a popular fishing hole just west of Susanville, California.
The Environmental Protection Agency (EPA) is scrambling to undo the environmental damage caused by their unwitting release of three million gallons of toxic waste into the Animas River, which contaminated over 100 river miles with pollution that extended from Colorado to New Mexico, and has now even reached Utah.
The animals were transported to the United States on a flight dubbed “Trip to Freedom” after Mexico outlawed the use of animals in circuses in January. Eight lions, a puma, two bobcats and a coyote rescued from circuses in Mexico arrived safely in Colorado and their new home at a wildlife refuge center.
According to a new national scale analysis and map of water used in hydraulic fracturing operations, oil and natural gas fracking in the United States is now consuming over 28 times the water it did 15 years ago.
Rising temperatures brought about by climate change are reducing the yield of wheat crops in the United States, a study published in the journal Proceedings of the National Academy of Sciences, or PNAS, said.
National parks in the Western United States and Alaska are some of the most pristine landscapes and waters on the planet, yet results of a four year study indicate that mercury contamination affects fish even in these protected areas.
Most United States residents feel that world leaders are “morally obligated” to fight climate change, according to a new poll commissioned by Reuters.
At an eye-popping price tag of $2.7 billion every year, a new report says the United States could meet the national goal of reducing the “dead zone” in the Gulf of Mexico.
