Which of the following is a possible cost of using renewable resources? a. loss of animal species b. land degradation c. lower availability of freshwater d. all of the above

There are different kinds of renewable sources of energy available to human kind from nature

a) Sun

b) tidal energy

c) wind energy

d) hydro power

e) wood

So if we use excessive of wood it means we are cutting forests

this will lead to land degradation and loss of animal species (forest is home of wild animals)

similarly for hydropower generation we need to use freshwater which will get exhausted and it may lead to lower availability of fresh water

hence the correct answer is all of the above
