First of all, overfishing reduce the number of fishes. And it will take decade to recover. 90 percents of predator fish, such as, shark and tuna has been declined in half of century.
Second factor is pollution. Sometimes, land pollution leads to ocean pollution. This cycle makes marine life short. Although this negative effect, many ships dump at least sixty five million gallon of trash a year.
Third factor is climate change. Climate change causes new disease outbreak in oceanic environment, affecting every fishes and oisters. And climate change also affect mammal that depend on fish.

Jae-Hyoung,
Again grammar is your biggest issue. I've made changes below to reflect corrections.
The lecturer said the world's oceans have been destroyed because of three main factors: Overfishing, pollution, and climate change.
First of all, overfishing has reduced the number of fish. And it will take decades to recover. 90 percent of the population of predator fish, such as shark and tuna, have disappeared in half of a century.
The second factor is pollution. Sometimes, land pollution leads to ocean pollution. This is because of the runoff that occurs when farmers use toxins to help keep bugs off of their crops. This cycle cuts marine life short. Although this is obviously a negative effect, many ships continue to dump at least sixty-five million gallons of trash a year into the ocean. The third factor is climate change. Climate change has caused new disease outbreak in oceanic environments, affecting all kinds of fish and oysters. And climate change also affect mammals that depend on fish for survival.
