There are numerous global environmental issues that we face today. To begin with, massive amounts of gas emissions are released into the atmosphere, causing global warming, glaciers to melt, and sea levels to rise. Furthermore, many species are endangered; if they go extinct one day, the eco system will be disrupted, resulting in a series of negative consequences. Because of over-exploitation of land, the soil may degrade and be unable to produce enough food in the future. There are numerous types of pollution that endanger human existence, such as air pollution, water pollution, and light pollution. Because of the reduction of many natural resources, Planet Earth is experiencing the exhaustion of numerous energy sources; that is not sustainable for human development in the long run.
