There're a lot of errors, especially in determiner use throughout the essay. Let's take a look at the introduction:
It is the case that in the latest decades, the environmental issues have been regarded as a topic of concern all over the world, especially in the industrial countries.
The phrase "It is the case that" should be eliminated as there's no need to emphasize.
The environmental issues are not referred to and made known in advance. So you should only write "environmental issues" instead of "the environmental issues". It is the same case with "the industrial countries". You haven't mentioned which particular countries, just "industrial countries" is okay.
You can write: In the latest decades, environmental issues have been regarded as a topic of concern all over the world, especially in industrial countries.
While I hold the belief a desperate shortage of public responsibility for saving the nature springs from numerous underlying causes, I also suppose several effective solutions should be taken into account.
The colloquialism "hold the belief" is inappropriately used. You can say "I believe" instead.
The determiner the in "the nature" is misuse, only "nature" is okay, or you can either say "the environment".
More importantly, the sentence structure "While ...., ......" was wrongly used. For example, this structure can be used in such sentences as "While I believe social networking can be rewarding in terms of socializing, too much exposure to social networks can be detrimental". In this example, while was used as a substitute to although. In this sentence structure, the two clauses must contrast each other.
You can write: I believe a desperate shortage of public responsibility for saving the environment springs from numerous underlying causes. However, this can be dealt with by taking several efficient solutions.
