Why amazon forest is being cut and cleared ?

Both B and C.

a-For cultivation of 'Abelmoschus esculentus'.

b-For conversion to grasslands for raising beef cattle.

c-For cultivation of soyabeans.

d-Both B and C is the correct option.

The Amazon rain forest (it is so huge that it is called the ‘lungs of the planet’) harbouring probably millions of species is being cut and cleared for cultivating soya beans or for conversion to grasslands for raising beef cattle. Besides total loss, the degradation of many habitats by pollution also threatens the survival of many species. When large habitats are broken up into small fragments due to various human activities, mammals and birds requiring large territories and certain animals with migratory habits are badly affected, leading to population declines.
