Question

how people increase the amount of gases in the atmosphere

Answer 1

Every year the world’s industry pollutes the atmosphere with millions of tons of dust. During many processes poisonous gases are thrown out in the air. These gases not only make the air dirty and unsuitable for breathing but also destroy the ozone layer. The atmosphere pollution also causes the greenhouse effect. If there is much dirt in the air, it does not let out the sunrays. It means that the climate becomes warmer and warmer every year.  The danger is that a warmer climate causes the melting of the Arctic ice and the rise in the level of the World Ocean.
