While I was watching Sir David Attenboroughs documentary "7 worlds, 1 planet" one scene really hit me.
It showed the Albatross, a bird I had heard of, but never really looked into. They are great, beautiful birds that live on the tall ledges of rocky mountains that sit over the sea. The episode was mainly about how they are affected by climate change, especially their chicks.
You see, Albatross can't detect which chick is theirs by smell, sight, or calls. The only way they can tell which chick is theirs is if it's in their nest. If it's to the side of it, and not on the nest, then the parents don't realize it's theirs.
Climate change is rising the sea levels, and wind levels, this means while both of the chicks parents are gone to fetch food for a good few days, the weak chick has to stay in it's nest while the wind rages. Obviously almost all chicks blow out and don't survive, and even if they do, they have to climb back up onto the nest or they while starve or freeze.
