Here is a link to an article by "The Verge". Basically, it is "NFTs 101". Near the very end of the article is the question, "Will trading my Logan Paul NFTs contribute to global warming and melt Greenland?" The answer is why "people are being upset with Neopets".

However, to quickly summarize, non-fungible tokens (NFTs) are, basically, digital "art" or "property". Blockchain is used to track ownership (digital ledger, so to speak). Blockchain is also what cryptocurrencies (Bitcoin, Dogecoin, Ethereum, etc) are based on. Mining cryptocurrencies, and/or making NFTs uses a lot of electricity. Fossil fuels are still used to create electricity, and use (of) can lead to global warming/climate change. People are upset at Neopets for wanting to create NFTs, which consumes electricity, which can lead to global warming/climate change.
At least, is what I believe the "whole NFT thing" is, on Neopets.
@jellysundaeYou know, the names could be used as adjectives, in a way. Only we on TDN/Neopets may understand, but I could say I was having a "Rico S" kind of day, and hoping tomorrow will be more like an "Alice W" one...
