It would continue even if we disappeared today. We have spread invasive species all over the place. Many of them haven't even been noticed yet. This includes stuff like soil fungus. Even when we do notice, we do nothing. Cats are a huge problem, but obsessed cat lovers are well-organized politically. They show up in force at every town council and country commissioner meeting where a cat issue comes up, defending stuff like giant feral cat colonies right next to the beach where endangered beach mice should be reseeding the grass that holds the beach in place. [edit: getting my cat lover downmods... but this is an actual problem causing beach erosion in Florida, and there is indeed a giant cat colony in my area that isn't more than 500 feet from the beach] If we disappeared today, the extinctions would just continue.
