There are a lot of species we need as they participate in the web of life with all the systems inside it. In the case of the bee the system involves plants creating nectar to attract bees that can help them pollinate. In the case of tigers, they keep certain prey species populations in balance so they don’t eat all vegetation which can have negative knock on effects . We can replace tigers in their role relatively easily whereas bees pollinate at such a scale that we currently cannot replicate what bees do, so losing them unlike losing a tiger would break a part of the web of life which can spell disaster.
Others have pointed out how bees, and other life forms, are key in the global ecosystem.
I think it’s worth pointing out that it’s not like if all the bees die then all life on Earth or even all humans on Earth go down with it. It just won’t be pretty to live in that world and many will die, but life will go on, adapt and eventually just carry on as it has for billions of years.
