NOAA announces largest-ever Gulf of Mexico ‘dead zone’

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.

The wall between the United States and Mexico will also affect animals

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.
