One of the problems we Frum Yidden have – or should have – with environmentalism is their logical conclusion against population growth. If one believes carbon dioxide is bad for the environment, there’s no way to escape this conflict. We can’t simultaneously believe that we need to reduce our carbon footprint yet actively increase our numbers.
Yet Hashem in his infinite wisdom commanded us to be fruitful and multiply. He did not ch”v indirectly command that we destroy our world. So for many of us, the logical conclusion is that the whole notion of global warming is hogwash and Hashem will take care of his world, while we continue to populate and “pollute” it.
