there is a group of scientists that believe in GW. another group disproves this. there are two sides of a coin.

AFAIMC, i saw the pasig river in the '60s. kulay brown na ang tubig pero pwede pang paliguan, at walang amoy pusali. ngayon, halos di mo na malapitan ang ilog dahil iba na ang 'halimuyak'. this is because human activities in the city had polluted the river.

GW or not, we should strive to keep the city clean. hindi ba maganda kung makita natin ang ilog na maraming isda; na hindi nakakalason ang tubig?
the clean air act helped in reducing the smog along edsa. sana maibalik ang dating ganda ng metro manila. let the scientist decide among themselves if GW is an issue or not. Manilans deserve a clean environment.
