The Conservation Angler’s recent newsletter has some really good stuff in it, I suggest you check it out. One slightly off-topic comment: for my day job I have spent a fair amount of time pouring over research on Bitcoin and Blockchain. There is a link in TCA’s newsletter to an article that does a reasonable job of discussing Bitcoin’s environmental impact at a high level, but leaves out something that continues to stun me. Given the enormous computing power required to run the Blockchain and mine new coins, the preponderance of server farms dedicated to this task are located in China due to their cheap, coal-based electricity. The result is that Bitcoin is responsible for about 60 million tons of CO2 emissions annually, an amount that is increasing. It is projected that Bitcoin will soon emit more CO2 than Japan, currently the 5th largest emitter in the world.
