The coverage of forests in the countries of the world is very important because nature is what makes human and animal life possible. Globalization and the accelerated growth of technology have affected forests in most countries of the world.
One of the reasons why forest cover has been lost in the countries, is the high contamination and the second is the accelerated felling of trees to obtain wood, for example Australia in the year 1990 had 21.9% and in 2015 it decreased to 20%; Brazil went from 62.2% to 53.5%. On the contrary, Chile and New Zealand increased their percentage of coverage, the first went from 20.4% in 1990 to an approximate of 22.0% in 2015, and the second from 28.8% to 32.3% in the same years.
