Oh yes not that im going to help but i got sum support asking me from other classes so i mite as well bring it out to the whole class again...

Remember Mr Chin telling us about greenhouse gases, main 1 being carbon dioxide? Yar true...it only disintegrate after at least 100 years so the main fraction of heat was trapped by carbon dioxide...whereas the problem with ozone depletion(erm related so i did some research on it as well...) is chlorine...i found the formula for CFC...Cl2F2C... and due to heat it breaks down into chlorine, carbon n fluorine on the ozone layer... n from there, the carbon was mixed with the oxygen(again) to form carbon dioxide... oh yes scientist have not found a way to solve this problem...

Think about it. Whats the point of finding a solution if the rate of destruction is bigger than the rate of solution? U see, the Americans r arldy giving so much problems to the society by using so much oil...much less us. If we found a solution will the water level of the sea deplete to the original height? I doubt so. The ice in the two poles r melting even wen the conditions can still go under 0 degrees...so even if we found a solution the temperature will still remain n even continue to rise...we r still receiving the same amt of sunlight as b4 industrialization. The heat which r trapped will reduce but the heat loss due to the ice on the two pole will hav been arldy reduced. how much ice can we recover?
...

Think about it. What is the real problem?

And i welcome all feedbacks n I"m not showing off k?
