The given graph shows the data in periods from 1990 to 2015 with the percentage of different countries with lands, covered by trees. There are four columns, the first of them represents countries, and the others represent the years with the lands, covered by trees in percentage. Overall, it seems like the biggest changes have only affected Brazil with it noticeable decrease from 1990 to 2015, while others didn’t experience a significant change.
The first year, 1990, demonstrates the difference between countries in the beginning. While Chile and Australia had a similar amount of covered land 20.4% for the former and 21.9% for the latter, Brazil was at its peak with 62.2%, and this is also a record for all countries for the last 25 years. In fact, only New Zealand didn’t show anything remarkable at 26.8%.
In the next 15 years, some moderate changes happened, especially in Brazil. Brazil had experienced a moderate fall with 10% to 52.5%. From that moment, Brazil followed its downward trend all the way to 2015. Chile and Australia no longer share the same percentage, because while Australia experienced a slight decrease to 20,3%, Chile, conversely, had a markable rise to 23.7%. Also, like in 1990, New Zealand didn’t show any enormous changes, only continued its tedious growth to 31.0%.
The last year, 2015, demonstrates how Brazil’s downward trend is not ending, it experienced a significant decrease of 12.4%. But instead of dramatic Brazil’s trend, Chile and New Zealand both rose remarkably, with moderate growth for Chile at 7,9% and a slight New Zealand increase at 1.3%. Brazil wasn’t the only country, that also encountered with downward trend – it’s Australia, which dropped from 21.9% in 1990 to 16% in 2015.
