Air pollution
vendredi 4 novembre 2016 à 01:0090% of the world's children live in places with excess air pollution, which can cause them permanent health problems. 15% live in extreme pollution.
However, an even bigger problem is that there are over 2 billion children. People are making so many that the population is increasing.
We should aim to have only 1.5 billion children, 20 years from now.
