Are hummingbirds becoming endangered going to affect us?

Yes, hummingbirds have co-evolved with many flowers. These flowers provide the hummingbirds with nectar. When the hummingbirds access the nectar some pollen falls on their head and wings. So when they move to another flower, the pollen is transferred. So many flowers are dependent on the hummingbird for pollination. Hummingbirds also eat a lot of insects for protein. These insects might stand a chance to overpopulate the environment with the hummingbird. The hummingbird has a very important role in our ecology. Let's not forget the beauty they provide for us to watch.
