Fruit bats are incredibly important to their local ecosystems. They help pollinate indigenous plants, control insect populations, do various bat things.
They are also threatened by habitat loss and human activity.
Batzilla is a Youtube channel of an Australian who rescues fruit bats which have been found in precarious situations. In short and sweet videos, often of the recently rescued bats eating, they explain how they are important to the local ecosystem and how to help mitigate and eliminate the man-made risks they face. They also have a Facebook page which goes into a bit more detail.
