To understand the current state of Web3—that future version of the internet that proponents promise will be decentralized and better—it helps to take a look at Adam Neumann and the “Goddess Nature Token.”

Mr. Neumann is, of course, the former head of WeWork who in 2019 was ousted from the company he co-founded after an epic run of oddball leadership and financial adventurism. The Goddess Nature Token is an effort to marry Web3 technology with environmentalism and is the core product from Mr. Neumann’s newest venture, Flowcarbon. That startup late last month raised $70 million from a long list of investors led by venture-capital giant Andreessen Horowitz.
