Question

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

Answer 1

Answer: All of the above.

Explanation: The possible cost of using renewable resources are as follows.

Loss of animals species: The cutting down of trees for wood and other materials that is a renewable source of energy leads to habitat loss of animals residing in that forest.

Land Degradation: The loss of biophysical property of soil can be said as land degradation. It is induced due to human activities and some environmental factors.

Lower availability of freshwater: The consumption of water for agriculture and other purposes are increasing so there is a lower availability of fresh water for consumption.

Answer 2

Answer: d. all of the above

Renewable resources are those which can be replenished or reproduced at a faster rate. But heavily decrease in the volume of these resources sometimes cannot be compensated.

a. Loss of animal species: Hunting and poaching of animal species has limited the population of endangered species to derive valuables like horns, skins from these animals for human use.

b. Land degradation: Landmass occupied by natural forests and other natural biomes are cleared for human use like agriculture, mining, urban development. These lands are loosing their natural potential and are treated as waste lands.

c. Lower availability of fresh water: Water from water bodies like lakes, rivers, groundwater, ponds are polluted by industrial, agricultural wastes making water unfit for human use. Groundwater are pumped out to maximum amount but the same level cannot be maintained by natural sources of water such as rain, agricultural field irrigation, river or any other means therefore, limiting the level of water in grounds.
