Topic human activity vs environment The problem of development versus environment has now been in the limelight Nowhere is the clash more visible than in China, where the world's largest population faces pollution, deforestation and acid rain on a large scale Under this circumstance, some people argue that the earth is being harmed by human activity whereas others still feel that human activity makes it a better place to live, however as far as I am concerned, they are not conflicting issues How to define human activity? I deem this is the premise of judging the influence it bringing to the earth Yet, human activity includes diverse aspects, good and bad, non can be negated As a matter of fact, in order to possess more plow lands as well as more resources such as wood, petroleum, mine and natural gas, there has been a rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on earth, what is more, as the human population continues to expand, it will negatively affect one after another of earth's ecosystems, and the result is irreversible Now humans are beginning to destroy marine ecosystems through other types of activities, involving disposal and run off of poisonous waste Not to mention the wars that exactly no good to the earth Can you imagine what terrifying result will it lead to if continuing such kind of human activities? In contrast, the list of favorable human activities also seems endless The discovery of electricity is a good case in point Without electricity we will have nothing to except for sleeping during the night; without electricity the factory will not be able to produce enough things to satisfy the society; without electricity we even have no chance to take this TOEFL examination! Similarly, the finding of antibiotics did much to our world, as a result, saved many lives of not only human beings but plenty of animals as well Can you deny these merits that human activities brought to? As I have noted, human activity has both advantages and disadvantages to the earth It is correlated with what kind of activity it is Accordingly, we cannot simply figure out human activity good or harm to the earth
