Hi all, I am intend to take the TOEFL Test in this year and here is my first essay writing
Please give me your feedback :)

Topic:
Learning about the past has no value for those of us living in the present. Do you agree or disagree? Use specific reasons and examples to support your answer

Writing:

Whether learning about the past has any value for those who are living in the present is a provocative topic. Some people hold the idea that this learning is totally worthless because they think that it is better to let the past "rest in peace". However, in my opinion, learning about the past is necessary for the following reasons: it can shorten the time we spend to get knowledge; it helps us to avoid the mistakes in our lives; and it inspire us in our daily lives

Learning about the past can help us to shorten ...

Writing Feedback / TOEFL: Some people believe that the Earth is being harmed (damaged) by human [3]

Hi all,
Here is my second writing in TOEFL, please give me some comment :)

Humans Should Not Live on Earth Because They Destroy It

Writing:
Whether human activity is making the Earth a better place to live or damaging it is a debatable issue. Some people advocate the idea that human activity is advantageously influencing to the Earth. However, I strongly believe that human activity are having a bad effect upon our planet, for human are polluting the Earth's environment, exhausting natural resource and threatening the living of other species.

People are corrupting their ecosphere. In recent decades, concurrently with the increase of human consume, the waste discarded by human also multiplies. These wastes including household waste and industrial waste are so big that a "new" continent is now being formed in the sea from garbage. Furthermore, the industrial exhaust gases are adulterating the air, causing the insalubrious phenomenon such as acid rain, global warming or climate change.

Besides, people are draining the Earth's natural resources. These resources such as oil, coal... are vital for human activity, therefore nowadays, the exploitation activities of these resources are increasing dramatically to adapt to the infinite need of people. Researchers indicated that most of natural resources are un-recyclable and only several decades after, the Earth's natural resources are totally exhausted. At that time, human activity will be seriously affected due to the dependence on these resources.

Also, people are endangering other species' live. Hunting has been a fundamental activity of human for having food. Through million years of hunting, especially in recent centuries with the innovation of rifle and dynamite, people have killed many animals and even have made some kinds of them become extinct. Moreover, people, suffering from the population pressure, are expanding their living area; consequently, the living area of other species narrowed. This narrowing of living region is pushing many creatures to the brink of extinction.

All in all, from discussed reasons, we can conclude that human activity are gradually destroy the Earth since it is polluting the Earth environment, depleting the resource and imperiling other species' lives.
