Do you care about the environment?

Nowadays environmental issues are talked more and more in media and among scientists, scholars, etc. However, do public care about the environment that much? Do you notice that when you drive a car there's carbon dioxide emission to the environment? Do you notice when you fly between cities, countries, or continents there's carbon dioxide emission too? Do you notice any other environmental effect that you do very frequently or daily?

Yes. I care very much about the environment.

Hmm, that sounds nice, would you like to tell something more? Like how to you behave concerning the environment? I guess it's not easy not to drive the car just to protect the environment. In winter it might be possible though, public bus is convenient and warm than private cars, isn't it?
