I think the birds are disappearing because of the pollution in the air. Maybe birds aren't able to live in the air. Because of this, naturally, I am upset that they are leaving.
If the birds continue to disappear, it will greatly impact our ecosystem. This is because birds control their prey population, which is usually fish, birds, worms, etc. so they will overpopulate and die out because they will not have enough food to prey on. Another reason is that their predators won't have food, so they will die out as well.
Every year the amount of birds going extinct is growing, not only due to climate change, but also diseases and threats to their natural environment. This threats don't come only to changes in the atmosphere but also of some companies invading their space, such as large bodies of water to extract minerals, which could be avoided by stronger regulations.
