What exactly do you expect from us? Below you’ll find an amended version of your essay. You will please the TOEFL guys. The question is whether or not you will be able to compete with AI. I don’t think so.
A variety of activities can be carried out on a single piece of land. Agriculture and the cultivation of new crops to provide people with a variety of food; huge constructions can be undertaken to provide shelter for people; large industries can be opened to produce everyday things for people. But do we ever consider the animals that are part of our ecosystem? Do we ever consider that the land that is the tool for our prosperity is home to thousands of species? Just knowing the answers is not enough. Not only do we, selfish humans, never consider the enormous losses to the animals, but we don’t really care about the animals. I strongly believe that saving the land for endangered animals is more important than using it to satisfy never-ending human needs.
First, animals form a very important part of our ecosystem. Every single animal is a part of one food chain or another. For example, the pig eats the cat, the cat eats the mouse, and the mouse eats the tiny insects that hide in their burrows. When one of the animal populations is affected for any reason, the entire ecological balance is disrupted. Unfortunately, the losses are not limited to the animal brotherhood, but extend to humans as well. Many of the non-vegetarians eat pork, and when pigs are endangered, the food supply of the people who rely on pigs is disrupted. Thus, those same people are now relying on crops that cannot meet the gigantic needs of the entire human community, and a food shortage crisis is occurring.
Second, we as humans have an essential duty to our Mother Earth, that we must give back to the environment what we have taken from it. Saving the land for endangered animals is one of the first steps on this path. Since time immemorial, humans have had a tendency to take nature for granted and exploit it in every way possible for their own financial gain. This has led to deforestation, rising temperatures, global warming, lack of precipitation, melting of glaciers, and has many devastating consequences. Eventually, all these changes have led to long droughts, floods, disease epidemics, tsunamis, and volcanic eruptions. Only when people start acting on such alarms, only then can we calm the fury of Mother Nature.
So I think people should stop their nature-destroying activities and consider the lives of millions of other species before building new factories or constructing big skyscrapers. The government should conduct more and more educational programs to make people realize the seriousness of the situation and encourage them to adopt nature-friendly ways.
