3.1 Marine animal extinction
One of the major cause of marine animal extinction is the water pollution that cause by industrial waste, over fishing, human waste. According to Drew Brucker (October 9, 2017), more than one million marine animals die annually due to plastic entanglement. So, this huge number of marine animals that die every year will lead to an extinction of many of species on the ocean. That’s also will affect humanity in the end.
3.2 Human health
Water pollution affects us and every single living things on this earth because we all rely on water to survive. If fishes become polluted with water, human health will be endangered because the ocean is one of the primary sources of food. That’s also may lead to starvation.
