Moreover

, over-cultivation is approximately a quarter which is 28%.

On the other hand

, in the table,

Europe

causes

the most damage to the lands which is a total of 23%

in contrast

with that North America has a minimum proportion of damage which is 5%.

Nevertheless

, Oceania does not cause over-cultivation as in

Europe

which is 7.7% but 11.3 % caused over-grazing which is much more than North America and

Europe

. In the end,

Europe

has 9.8% of
