extinction


The giant panda is on the verge of being extinct such as many other animals. Some people think the main reasons of animals being extinct is natural disasters, but the biggest reason is because of us people.

All people have different opinions in how animals go extinct. Some people such as Al Gore think the reason animals go extinct is because of global warming but that’s proven to be a myth. Other animals can’t find food, which makes since but isn’t the biggest reason. Also, because they get attacked by predators. For example, a Gazelle's predator is a lion, a swordfish's predator is a great white shark, and finally a frogs predator is a snake. Another reason animals go extinct is because of natural disasters. Many natural disasters including volcanoes, hurricanes, sunamis, tornadoes, floods, blizzards, avalanches, earthquakes, and even lightning strikes kill off many animals.

People are the main cause that most animals go extinct. When people started building houses they destroyed many animal habitats. Also, when the hunters and gathers started they began to kill the wildlife such as buffalo. They killed about ¾ of all the buffalo population, but now it's not as bad because, the buffalo came back. When people made houses they cut down trees which animals lived in. They pollute the air and water with the huge factories that were made. Also, people killed animals for sport, such as hunting and fishing. There are many ways that people kill animals including the ones above.

In conclusion, many types of animals go extinct and there are many reasons that it happened, but the main reason is people. Today there are 3.5 billion extinct creatures right now and it may go up if we don't change our ways.
