I think any jew who has an inclination towards environmentalism should consider the following:
Rav hirsch writes that it’s not possible for a species to be extinct; this is based on a lot of sources. (Manu argue with this). Rav Hirsch also writes that אותו ואת בנו, the mitzvah of not shechting a father animal and its son on the same day, is because it looks like extermination.
How does this fit? If we are incapable of extermination, why would we be cautioned against this?
The answer is that Hashem runs the world and nothing we do will affect it physically. We can have as many kids as we are able to, and there will never be a shortage of food or space. We can bathe as much as we want, drive whatever car we want, and fly in as many airplanes as we want, and the world will be just as functional and physically healthy as ever.
Mitzidainu, if we engage in behaviors which look like extermination or destruction of the world (insert italics) to our senses, or in the cases of the torah (as above), then we are guilty lf that aveirah, but as seen by our inability to actually cause extermination, this mitzvah is for our own middos. Similar to having hakaras hatov to inanimate objects, i.e. Moshe not hitting the dirt or the water – it will affect HIM, not the object.
What does affect the world? Our aveiros. The more aveiros the world (and especially klal yisroel) does, Hashem’s brochos are stifled. That our material succcess depends on our fulfillment of the Torah is axiomatic in tanach and chazal – it’s one of the most discuss topics in neviim. Devorim 28, for instance. Ki savo. “Al azvu es Hashem”, “tachas asher lo avadta”, the list goes on and on.
Environmentalism that is taken to mean that we are stewards of ths physical health of the world, and that it is out carbon footprint as opposed to our aveiros that harm the world, are included in the rambams famous piece that says that when bad things happen, and we attribute them to mikroh, to chance…it is not only heresy, but it is cruelty, because in doing so the denier of hashgocha causes others not to repent and continues the cycle of sin and punishment.
Environmentalism from a torah perspective is therefore repugnant, a denial of Hashem’s running the world, a scapegoat for introspection and teshuva should there actually be natural catastrophe, and of course…an import from the goyishe world without a shred of source in Torah.
