Don't pollute the air with black smoke exhaust from your car that needs smog. You need to take your car to a smog shop or else you suffer the consequence of being a law breaker. Always throw your trash in a trash bin or any convenient trash can. Do not dump your trash and garbage on freeways, Pacific and Atlantic ocean! I know, I've seen people doing these and had reported them to the authorities.

be concerned to yourself in the first place.... if you have done this, you would end up caring for the environment.... I guess all of the above may define 'how', 'what' & 'who' will take care the environment... It's better to ask.... "When are we going to be concerned with our environment?"

To my mind,,everyone should protect environment! Not to polute area around us,,grow trees near our houses and so on. Evevrything in our hands...:)

The question has many answers and we all know in some way how to help our environment. The real question should be, does anyone REALLY care enough to help? Or is it just in style and that's what everyone is tallking about yet are doing nothing?

the environment is the thing most important at all to keep healty as long as we live ,so everyone of us should have the sense of responsibility and acting like one ,by pushing everything that may cause the pollution away,by keeping our streets clean.to sum up ,we all have to show and do our part of responsibility over the environment but in the right way.
