The hippopotamus is a very unique and interesting species. I don't think pollution is a major factor when it comes to the effect on hippos in East Africa. Pollution is a major factor when it comes to life in many places around the world. However, I don't think pollution necessarily affects Africa as well as it affects other parts of the world like, for example, California. Many people believe that pollution is killing animals around the world. To some extent this is indeed true, but not specifically everywhere in the world. In California, pollution is a huge factor in life living on land, flying in the sky, and even living in water. Plastic is one of the main sources of pollution. When people don't recycle plastic, it gets thrown into huge piles in an excluded area. Plastic is not degradable, so it does not deteriorate over time. Plastic that is washed up on coasts ends up in the ocean, affecting animal life in the sea. Birds and fish ingest small pieces of plastic as they try to feed on zooplankton. For every 6 pounds of pollution there is only 1 pound of zooplankton. Unlike California, Africa doesn't have as big of a pollution problem. One major factor is that the population is extremely less dense than that of California. There are approximately 5,000 people per square mile in the densely populated areas of California, while there are only 500 people per square mile in the few densely populated areas of Africa. There are not many hippos in the northwestern areas of Kilian Diers Marine BiologyMr. GirodMay 16, 2014continent, but there are many more in the south-eastern regions. Because the human population is small... in the middle of the paper... for the food chain, especially for fish," explains Marc Lunguy of the WWF. If the hippopotamus species instinctively moved away, the first loss would be people in the region that feeds on fish for their sustenance is rather simple. They stay close to water, never exceeding a maximum of 6 miles from the nearest water source 'Northern and Southern Africa Basically, the only part of Africa that is home to the soon-to-be-extinct animal is East Africa, Kenya, Sudan, Tanzania and Uganda are the cities most commonly known to host hippos range 10 to 150, which are mostly females and their offspring. They are led by the dominant male hippos who often fight, which is sometimes fatal, to be the leader.
