Nowadays, global warming is the most important issue in every country. A large number of people think that any human activities cause damage to the Earth. However, many people believe that the Earth is better than ever due to human activities. Before identifying my opinion, careful discussion is required.
- don't use Global warming in your hook sentence.it's better to use it as a main idea on your body paragraph. It is not advisable to
use the phrases " a large number" or "a lot" use "many" or stick to your prompt "some" and "others". If you intend to state your opinion
in the conclusion paragraph, you don't need to mention "Before identifying my opinion" in the intro paragraph.
- use Global warming as your main idea in 1st body and support it with ideas on how human activities can contribute to it
- use another phenomenon (opposite to Global warming) which could benefit the world in the 2nd paragraph. Again, state some ideas on
how human activities can countribute to it.
- summarize everything in the conclusion and mention your opinion.
This is how it is done in IELTS, if this is what you intend to do...hope this helps..
