Rav Aryeh Carmell ZT”L wrote at length about how “ecofriendliness” is part of the Torah and we cannot disrespect our environment. I suggest we all read his essays on the matter before proceeding further.
Though I do admit that modern “green” movements are mostly about making people feel better about themselves. Even if everyone in the US would use reusable shopping bags, the impact on the environment would be minimal. The main things we need to worry about are big governments and companies that account for 90% of the world’s pollution.
