Transcript of Humans Impact the Ocean

How Humans Impact the Ocean
Humans Have Impacted the Ocean Severely
#2 Plastic
Americans generate 10.5 million tons of plastic waste each year, but only recycle 1 to 2% of it.
#3 Overfishing
Billions of people around the world rely on fish for protein.
Many species like the Atlantic bluefin tuna for example, have declined to the point that they are now endangered.
Illegal fishing, poor fisheries management, and open access fishing have all contributed to the major overfishing problem we have.

#1 Water Pollution
In 2010, there was a huge oil spill in America by BP. Of the 400 miles of Louisiana coast, approximately 125 miles have been polluted by the oil spill. Over 1,000 animals (birds, turtles, mammals) have been reported dead, including many already on the endangered species list.

Sewage Polluted Water
In one week, an average cruise ship produces 795,000 liters of sewage, 149,230 liters of bilge water, and more than 8,120 kg of solid waste.
Over 80% of pollution enters the ocean comes from land.

In the seas of the Pacific Ocean, lies an island of garbage, nicknamed the "Great Pacific Garbage Patch". The heap of garbage is so big, it is as big as the state of Texas!
