main reason why agricultural land becomes less productive

There are wast variety reasons behind worldwide degradation, but the utmost reason according to the pie chart is over-grazing if I want to clarify it more, although grazing tends to require to worldwide, nowadays we are witnessing that the benefit of over-grazing does not outweigh its downsides and that is why humans should eat less meat and having a tendency toward being vegetarian. On the other hand, deforestation comes up as the second reason that I can mention. The population is increasing over the world and building homes has been rated as a priority for governments, so despite the fact that urbanization gives us home, it is actually ruing our ordinal home which is called “earth”. There is a positive correlation between population-focused and measured deforestation, Europe has selected as the top candidate in this caption, despite that we are calling it as green land, it is deforesting our plane more than USA and Oceania Devoting attention too much to cultivation is another our fault, Europe is on the top of the list again but apparently, Oceania approximately has not any remarkable role in this case.
