Today we watched an important video about air pollution. It said on a website that Wellington, New Zealand was the cleanest city in the world, how amazing!!! My wondering was why do they have thousands of factories in one little city and then the manager of the factory just leaves it to make the smoke turn into air pollution? In Ahvaz, Iran their air pollution is 372 micrograms per cubic metre and that is really bad. I think animals are being effected by the air pollution because they are eating litter and breathing in smoke.
