Environment: Pollution and Human Activity
Topic: Some people believe that the Earth is being harmed (damaged) by human activity others feel that human activity makes the Earth a better place to live. What is your opinion?
Nowadays the Earth faces a number of serious problems, such as the environment pollution, the increasing population, the fatal effects of nuclear weapons, etc. The problems arising from not just development in terms of science and technology but also the increase in human demands based on population and economy. According to Professor David Karoly from the Department of Earth Sciences at the University of Melbourne, it is time to take urgent action to slow global warming by human activities, because the impacts of human-caused climate change in many natural systems much earlier than previous studies had projected which are being seen (Proof: humans have damaged earth, 2008). There is inconvertible fact that in history of humanity, human causes detrimental effects on earth. Indeed, human activity affects nature and human environment.
For centuries, many activities of human have destroyed ecosystem of the Earth. Deforestation and over-hunting is one of the main causes of this serious situation. The world is very big, but natural resources are not endless. In fact, Dave Gilbert (2012) announced that nearly a fifth of the Brazilian forest has been lost since 1970. That means all of the trees, plants, insects, animals and people who live there either killed or forced to find a new home. The world population is growing rapidly, so people need food and shelter. Many food and housing means that they need more land from nature. Therefore, they cut down trees to build houses, deforest to plant vegetables and raise cattle. They destroy natural areas in order to expand cities and towns, and they overuse natural resources. Now people only can see some animals in the zoo because they have disappeared in nature. In addition, intensive and indiscriminate fishing in freshwater systems, such
