Human, who is last consumers on the level prey channel, has played the important role in the ecological system. Human contribute to protect the natural resources such as tree, water and air. However, some people argue that this activity wea conducted after we feel the risk of natual destoy. In the wide veiw point, human activity has given negative effects on the Earth rather than positive them. I firmly agree with this opinion with some reasonable points.
To begin with, utilizing the natural resources, people have enjoyed theur lives for a long time. When people feel cold, they made fire to make their bodies warm by burning trees. Also, after the invent of a car, people has consumed enormous amounts of oil. They might believe that we would be able to use oil ceaselessly. Without gratitude toward the nature, it is undoubtable that human has been dependent on the nature. However, as one of the issues considered seriously, human is facing the lack of the natural resources. Becasuse of annual low precipitation, it is hard for people to use enough water and we need to make a plan how to use it properly. Further, people have to find out alternative resources to keep human life.
Due to unlimited and unplanned uasge of the natue, people have the environmental problems such as air pollution, water pollution and gabarge treatment. Human has invented various stuffs to improve their lives and to enjoy convenient lives. The invents like a tire for a car and a plastic dish are represnetatives. Even though they make human lives more convenient and easy-going, people concern about how to treat them after usage because they never return into the nature. Sometimes people burn them out or bury them under the ground. However, these activities are not solution but temporary treatment. As a result, these activities make the nature damaged and further will threaten the Earth.
In conclusion, when it comes to overusage of the natural resources and environmental problems, I belieive that the Earth have been harmed by human activities and become worse and worse. The most important thing is not the development of technology or invents but the protection of the nature. |
