> I want poor people to stop losing their money to scammers Then your ire should be directed at scammers, not a specific implementation detail of their scams.

Not all cryptocurrencies are proof of work; proof of stake, for example, is increasingly common (Cardano is the biggest current example, and Ethereum is moving toward it) and uses negligible energy (and therefore releases negligible carbon into the atmosphere).
