Environmental conservation has become a trending topic in recent years. Pessimists claim that there is nothing that can be done to save the Earth, while others argue that human beings still have a chance to modify the situation. In my view, I agree with the latter and I will provide an explanation with examples.
First
of all, it is undeniable that human activities have brought a number of serious problems to the Earth due to the increase in human demands based on populations. Linking Words
For instance
, the average temperature has increased one Celsius since the 1800s, which mainly caused by deforestation, farming and burning fossil fuels. Linking Words
This

On the other hand
, others including me believe there is still hope because the awareness of environmental protection and sustainable development has raised in recent decades. To be more precise, many countries have started to tackle the negative effects brought by human beings, like reducing overexploitation of natural resources. Linking Words
Instead
, professionals are researching and finding other renewable and Eco-friendly resources to limit the demands on fuels. Linking Words
Besides
, afforestation is encouraged to offset the damage by deforestation. China is one of the best examples, which the overall forest coverage rate has risen from twelve per cent in the early 1980s to twenty-three per cent currently. Linking Words
As a result
, the air quality in China has improved dramatically compared with thirty years ago.
In conclusion, even if human activities have caused grave consequences and even some permanent damage to our plants and wildlife, it is not completely irretrievable as long as human beings can learn from previous mistakes and insist on sustainable development.Linking Words
