Topic: Do you agree or disagree with the following statement? Human activities have enhanced and improved the Earth. Use specific reasons and examples to support your answer.
For approximately ten thousand years, humans have dominated the earth. They have developed societies, civilizations, and eventually developed countries. During these processes, human beings also developed a method of efficient survival. For example, they realized that rocks and logs are great sources for constructing buildings. Also, people found out that wood, coal, and oil can be used to produce a powerful energy. However, excessive use of resources has led to a devastating result. Problems including global warming are occurring at an increasing pace.
Usage of oil and coal as a source of power for machines has made this world a fine and convenient place to live. However, the harmful gases that machines emit are leading this earth towards a serious environmental problem. These harmful gases are trapped inside the atmosphere, and are building up, making the Earth hotter and hotter day by day. This is global warming, and it will be more severe every year. The problem is that the glaciers in Antarctica and the Arctic ice sheet are melting fast, thus causing the sea level to rise. As a result, frequent strikes of giant waves could occur. Thus, as human beings started to burn up the fossil fuels for their survival and convenience, the Earth’s condition slowly started to degrade.
Also, cutting down the trees has done nothing but decrease the amount of oxygen in the Earth’s atmosphere. Obviously, trees emit fresh oxygen, and absorb carbon dioxide. The biggest place where this phenomenon happens is the Amazon rainforest. However, nowadays, people cut down the trees of the rainforest and make farmland. Not only in the Amazon but throughout the entire world, forests are disappearing fast. As a result, the decreasing levels of oxygen are going to get worse and worse.
In conclusion, human activities have done little but worsen the Earth’s condition. The excessive use of fossil fuels has induced global warming. Logging the forests has resulted in lack of oxygen. In this situation, we should promote an alternative source as a substitute for the normal fuels that we use, which pollutes the air. Also, planting trees could help producing more oxygen. The Earth is not merely a planet. It is our home, and we should cherish it with great care and help.
