What’s the most horrifying thing that has happened in the past 25 years?(r/AskReddit)
This is probably going to be buried, but as a biologist I have to say the alarming loss of biodiversity. Even things like bats, which can live in human structures and eat plentiful insects, are dying off at alarming rates. Bats are worth guano-tons of money to the US and very few people seem to care. It’s almost as bad as the current amphibian die-off.
Edit: I can’t recommend this book, Last Chance To See by Douglas Adams, highly enough. It’s a bit over the 25 year window of this question, but they did a television series starring Stephen Fry a few years ago that is great.
