Then please consider your own logic. Delete your account and make place for someone with manners.Why should I care about some obscure species? They die off and make place for others. Its called natural selection
It never hurts to check your local conservation departments and see if they need aid. It's always nice to help your local community. However if there is a certain animal you love that is endangered you can always spread awareness and help them.
There are so many causes I don't know where to begin honestly. Do some exploring and find an ecosystem, animal, or charity you like and go from there.
There is a few, non-profit bird hospitals around where i live, sustaining itself on small donations and voluntary work. People donated money, and got reservation rights for one of the hospitals, and now after years, it's visible that they are succeding. Since i was little, i can see a lot more birds, what was barely if ever visible around here. Mostly birds around water, since i live beside a river. If people give a little care, things can easily be achieved.
Around my home, there was an awareness rising about Fork tail Swallows. They dropped in numbers greatly, when i was little. So i personally have several Swallow nests around my house. Even if it "ruins" the look of the house itself it doesn't bother me much. Swallows leave stains, and dirt around, but meh... i can clean it up. I have my outside cable lines adjusted in a way, that Swallows can rest under my roof during hot summer days. Beside that i leave mud pools around, so they can repair/build nests. I can see a lot coming back every year, and they are growing in numbers. And since Swallows are natural predators of flies and mosquitos, and since i live beside a river, where mosquito infestation is common, even i gain from keeping them around.
Every little matters in the whole. Even if you can only effect few, it matters. Species can be saved if people give a damn about problems.
Here is a picture of them during the beginning of Fall.
