I have a basic understanding of what an ecosystem is. In a stable ecosystem, everything balances and keeps something else in check. If herbivores reproduce too much, the size of their population means they eat up all the edible plants in the region and all die out as a result. As such, there are predators, who hunt and eat the herbivores. A similar principle applies here for keeping THEIR population in check.
With oxygen and carbon dioxide, we humans convert one to the other by breathing and the plants and trees convert it back with photosynthesis. We do something for each other.
All this and more is part of a balanced ecosystem the stability of which everything depends on.
Every living thing (and many nonliving things) is part of an ecosystem, and most of the things I can think of, from microscopic organisms to the tallest giraffes and the heaviest whales, ultimately do something productive for it.
Except pigeons.
What the fuck do pigeons do for anything?
They eat the things we throw away, and they shit on the things we don't.
If you love something, and you keep it outdoors for long enough, it will inevitably be shat on by a pigeon.
That pigeon was likely just eating some breadcrumbs or something that you dropped the other week, too.
I seriously have no idea what pigeons actually do to benefit anyone or anything.
They are nature's most ungrateful freeloaders.
Fuck pigeons.
