The human activity is likely the most responsible for the changes observed in the world’s rainforests.
Human activities like deforestation- for construction of buildings, factories, schools, etc. has led to the decrease in rainforests. It has also affected the climatic conditions.
Option (B)- Human activity is the correct answer for your question.
Here, I have presented the devastating effects of Human activities over the rain-forests of the world.
It has been estimated that every single year a forest area that in the size of New Jersy (22,591 Km2) is destroyed by human activates.
Some of the main reasons for deforesting world’s rain-forests are
- For extracting minerals and energy
- For timber and fire
- For small and large agricultural farms
- For making grazing lands for cattle
- For the making of paper
Apart from humans, climate changes which a part of it is induced by humans are also found contributing itself in the destruction of rain-forests by inducing droughts and floods in frequent manner.
