Answer 2

Methane is released from the evaporation of gases from rubbish and dead organisms like plants and animals. It is extremely important to avoid making piles of rubbish around the streets to be exposed to the atmosphere and it should be put in containers.

CO2 is released from the burning of fossil fuels in the bushes and vehicles.
It is important to use alternative ways of fueling vehicles such as electricity, hydrogen or biofuel. That way, the emission of CO2 to the atmosphere will lessen.

Conclusively, with the lessening in the amount of both gases released, the global warming effect can also be diminished.
