Blockchain is an increasingly popular technology with quite a few applications and iterations, such as Bitcoin, Ethereum, and Non-fungible tokens (NFTs), but can they aid conservation? The answer is complicated. Some conservation groups are trying to use them for fundraising. Other conservationists are exploring the technology for the ability to track and trace payments for ecosystem services. However, downsides abound and depending on which form of the technology you use, they can be impractical, environmentally damaging, or both. Author, Brett Scott, joins the Mongabay Newscast to discuss these complicating factors, some of which he writes about in his new book Cloudmoney: Cash, Cards, Crypto and the War for our Wallets. Also joining the Newscast is journalist Judith Lewis Mernit, who reported on the Bitcoin mining surge in the US state of Texas and the rising energy prices pushed on to consumers.
