comment: why we should protect the environment ?

The temperature of the world is decreasing more and more.
Scientists have found out that global warming is caused by Methane and CO2. If we do not do anything, we will face many problems. The polarcaps will melt and polarbears will lose their habitat. Coral reefs would die. If colar reefs die, fish will no longer have food.
We should find a solution. For example riding by bike instead of driving cars.

Please correct my comment :) Done! :) Very good

Here is my correction:

The temperature of the world has been increasing year by year. Scientists found out that global warming is caused by the amount of Methane and Carbon Dioxide gas in the atmosphere. If we do not do anything, problems will arise. The polar caps will melt and polar bears will lose their habitat. Coral reefs will also die. When coral reefs die, fishes will no longer have food.

We should find solutions, such as riding bicycles instead of driving cars.

Hope that helps!

All I have to add is:
