Air Pollution

Today we watched a important video about air pollution. It showed the top 10 most polluted cities in the world and had some effecting music to go with it. Number 1 was Ahvaz in Iran. They showed you some photos to go with it and you couldn't even see buildings in the back. The air was yellow and when people drive around they have to have their car lights on in day time!! The problem is that people are putting factories in poorer countries and cities. Then they just leave them and don't look after them and then the smoke makes air pollution. Then we visited a website that said the cleanest city's in the world and Wellington New Zealand was number 1!!! Go the Kiwis!!!!!!
