To understand how extinction affects us and the earth, you need to understand what it is. There are several definitions of extinction but not all of them mean the same thing. In my opinion, extinction is when a species or organism is no longer existing. So, the species is no longer on our earth and no longer comes into existence. All over the world, animals have gone extinct for several reasons. For example, habitats issues, food shortage, and climate change can all be factors of extinction. But another cause of animal extinction is humans, they kill the animal for one part of its body and sell it. For example, an elephant is killed for their ivory and it's then sold to make money. I believe that's not right. Elephants are now one of the few animals that are going extinct. Over 905 animals are already extinct and the numbers will double over time. In my opinion, each animal was put on this earth for a purpose, some to feed other animals, or to help mankind.
Animal extinction affects us in so many ways, one being the food chain. The sea surface temperature continues to rise, which affects the animals in the water to being close to extinction, like plankton and other smaller species. If that continues it can affect bigger species on our food chain like fish and whales, one of our major food sources. In addition, people use medicine everyday and we retrieve those products for medicine from plants. To live, the plants need to rely on insects for pollination and if the number of insects decrease, the plant will struggle to survive and will eventually die. Also, with the extinction of animals we will be more open to diseases. Many animals have resistance towards certain health problems, including Lyme disease.
Those animals help the disease from spreading to other animals and humans. Without those animals, the diseases could spread and will put humans at higher risk to getting those diseases. Plus, with the decreasing of animals, the economy will lose several jobs like fisherman, hunter, and beekeeping, which will put our economy in a bad place. That's why instead of helping with the extinction of animals, we should prevent it. Personally, I love animals and I believe they are a humans best friend and they should stay on this earth as long as we do.
