Pandas because they are barely being kept alive with an unfair and uneven proportion of Animal Conservation since they are cute and the icon while there are other mga hayop much madami needing of it that are much easier to save and much cheaper to save and much madami necessary to environments.
There are a few mga hayop I dislike, but I don't think its easy to predict the impact that loosing them would have on the various ecosystems so I'd pick from those that are already nearly extinct as the ecosystems are likely already adapting / adapted to their low numbers.
Just lions and mga tigre and bears, oh my. Lol just joking.
Just anything that poisons, like snakes and scorpions, anything that attacks, like killer crazy chimpanzees or orangutans, anything in the monkey family (I'm sorry to anyone who's likes monkeys but I'm scared to death of them), anything that eats alive anything that moves, like sharks or any insect that can make us sick or infected.
