save our earth!

I really think its time to worry about our earth's environment.
just a small point out of the various kinds of pollutants.
CFC is emited everyday from aircons and refridgerators(which everyone uses!!)
this causes a serious greenhouse effect. One CFC molecule can trap as mush as 10000molecules of carbon dioxide causing the earth going to be veryhot. And to make things worst, it can remain in the atmostphere from 1century to 20000years!!!So it basically builds up year by year you know!!!
and seriously, the only good human is a dead one, can act as a fertilliser for plants.

Nuclear weapons will destroy us long before that happens.

wah today i had geog on this u noe u r repeating my lesson...
cfc, halons , trichlorothane,tetrachloride are some harmful gas...cfc can be found in aerosol cans, air cons and refrigerators. cfc contains chlorine...it causes harm when it reaches the earth's upper atmosphere... thus ozone depletion is caused. ozone depletion can cause eye cataracts, skin cancers, kill planktons which r the basic food for sea creatures and even slow down plant growth thus delaying our crop yield. -
wad age r u?? wad textbook r u using?? lol!!
-
but wad i learn one chlorine molecules can trap 100 000 oxygen atoms... aiya forgot lol
-
sec 2 lol! erm geog interactiveOriginally posted by davidche:wad age r u?? wad textbook r u using?? lol!! -
oh no!! im also sec 2!!!!!!!!!!!!!!!!!!!!!!!!!
-
Oh no.
So is it 10,000 or 100,000? Can our darling Sec 2s make up their minds?
-
Knn, sec 2 worry so much for fcuk?
Don't you all have more important things to worry about like whether your Singapore Idol contestant will last the next round or not? -
carbon + oxygen2 = carbon dioxide
so it square root 100000 = 10,000 -
*tml check tb again* lol btw i dun watch singapore idol
-
actually we have finished the whole tb... lol just revising
-
Mebbe we shood all try to fart less lor

you have a point. Methane is also one of the increasing greenhouse gases.
The increasing number of cows leads to increasing numbers of belch and methane -
Unless you want to work in Green Peace next time when you grow up, knowing all this CFC shit is worthless.
-
Got a problem with that?Originally posted by davidche:you have a point. Methane is also one of the increasing greenhouse gases.

it is actually a pollution problems for a certain country in Oceania -
People are dying all over the world in wars and shortage of food and we are here trying to spend even more money on environment.
Sure protecting the environment will do good for human's future survival. But do you know that for every dollar ppl invest on recycling cans you could actually feed an entire family in Africa for a day?
Irony again as dogs are talking spa here while people else where dun even have water to drink. Course animals do have rights, but so do human.
