From a humanitarian and economical point of view, Bitcoin doesn't hurt the poor. It allows the unbanked to finally store wealth, as a counter to a local strongly inflationary currency. Besides storing wealth, also growing wealth, as pretty much the only option they have.
Unless you don't believe the narrative that Bitcoin stores/grows wealth very well, in that case...poor people can simply not use it.
Perhaps you mean to say that the distribution of coins is uneven. That's true, but not a problem Bitcoin aims to solve or can solve. Bitcoin is fair, the same rules apply to everyone. If a billionaire has a 1,000 Bitcoin and I have 0.1 Bitcoin, we both win or lose based on price action equally, relatively speaking. That's as fair as it gets. With Bitcoin, having lots of coins doesn't give you any new free coins, unlike fiat money.
The environmental destruction is overstated and rapidly changing as we speak. Soon the vast majority of mining happens based on renewables with a specific focus on stranded energy. And this isn't a vague promise, some 60/70% of the hashrate from China, which include most coal-based mining, is being wiped out in just a few weeks.
