look, science keeps learning
let's pretend Al Gore is completly benevolent in his attemps to clean up the earth. good. but the problem rest with industry and therefor heavily on government.
we (americans) will drive higher fuel efficient vehicles when the goddamn government makes them available and when the fucking numbsculls at the auto companies make them look good.
that's about all we can do. average citizens are not the major producers of CO2. industry is.
however, if any or no industrial changes are made, the earth will still change its terestial features do to natural forces. evolution occures biologically and cosmically. humans will have to adapt to survive regardless.
but, if industry cleans up, the environment improves and at least you've done a preimtive part as a involved person. at the very least, smog in the cities would decrease. i'm all for measures to limit polution. not for a political scare tactic, but because i love the earth. it grows so many wonderful plants. and i love the ocean. there's something about the ocean... i would like to see them both as clean as can be.
