The earth has a lot problems that influence life. Global warming, Species extinction, as well as Ocean acidification that all issues in human’s life. One major issue that has a major impact that should be talked about is Species extinction. This world has many species that keep the balance. When one species begin to die out the other species will reduce too. When this happens humans face the possibility of mass extinction and people can not live in earth anymore. They need to find the way to save them.
Human activity has influence species extinction. For example, Tim Flannery says,
“Since human first wandered from their original habitat in Africa. over fifty millennia age. They have radically altered the environment wherever they have gone often at the cost of the animals who’d raled the wild before mankind’s arrival.”(Flannery 2001)
Humans have killed a lot animals because they need something from this animal like it’s meat, coat even teeth. For example, there was an animal named Quagga that lived in Africa. This animal look like a zebra but half his body was like a zebra and the other half of his body was like a horse. (The reason the Quagga went extinct due to overhunting. People were hunting this animal for meat and clothing and its fur. In 1883 the last Quagga dead in the Artis Magistra Zoo in Amsterdam and now the Quagga is gone forever.
Another cause for animal extinction is due to the loss of animal habitat. Humans take a lot of the animals land because they need more space to live. Because of this current Urbanization, there is a large amount of deforestation. They become deserted because they don't have trees to cover them, water in the soil is lost. Some any animals can not live because his land is destroyed and some plants because human excessive picking and environment change they never grow anymore. For example, the panda almost died out because humans took a lot space which destroyed the pandas food source, bamboo. The panda was also hunted for it’s fur because it is worth a lot of money, this also hurt the panda population. The loss of animals has a big impact on our environment.
Changes in the environment also have a big impact on species extinction. Today humans have a lot of environmental issues, global warming being one of the biggest problems we face. Due to global warming, some animals may begin to die out like the Polar Bear:
“As climate change melts sea ice, the U.S. Geological Survey projects that two thirds of polar bears will disappear by 2050. This dramatic decline in the polar bear is occurring in our lifetime, which is but a miniscule fraction of the time polar bears have roamed the vast Arctic seas.”(National Wildlife Federation,2014)
Because of global warming ice caps melt which is making it harder for white bears to reproduce and they have less ground to hunt on for food. Other species face the same problem, like the sea turtle. Sea turtles need beach to reproduce but...
