Nowadays, people have to suffer from seriously environmental degradation due to recent the boom in economic economic boom and innovatively technological development advanced technology. Some people contend that the sole and perfect (be aware when using extreme words such as perfect/sole) approach to handle this headache (unnecessary) problem should come from the universal cooperation.
It can be firstly noticed that the impact of environment tends to be on global ratio, requiring the transnational unity to sort out this issue. A river or a rice paddy can be obviously adversely affected by chemicals, toxic toxic chemicals or even harmful pesticides released by nearby countries. and pollutants emitted thousands of miles away. Likewise, destruction of others indigenous resources such as deforestation or extremely polluted beaches in a country (repetition of "country") is more likely to impose a severe danger on the environment and economic improvement. Undoubtedly, such outcomes are negative for every country in the globe. Therefore, individuals should join hand to retrieve the disgrace of environment which they maybe incidentally cause for improving living standard. (maybe try to rephrase this sentence?)
Equally important though, the exchange of goods, technology, knowledge and human and financial resources (too many nouns, try to shortlist them) can be easily obtained. Due to the prompt deterioration of the environment, the quick and best method (what method are you refering to? its not very clear) to the problem has played an essential role. Environmental impact in developing nations is more serious than it is in the prosperous ones. Less wealthy nations are incapable of addressing the downgrading of environment fruitfully because of the shortage of finance and lack of up-to-date technology. In simpler terms, international alliance can tackle with great efficiency and at lower expense.
In conclusion, cooperating with each other, countries can preserve the environment with the least use of resources. Worldwide union often not only makes optimal use of human and natural resources but also recovers the damage of the environment.
1/ Beware when using synonyms, they might not fit in with the context
2/ I can see that you try to write more complex and longer sentences but some of them do not flow well (coherence)
3/ Overuse of adjectives and adv + adj + noun, they can sound awkward. eg innovatively technological development
Hope this helps. Please let me know if any of my comments are incorrect.
