Forests occupy more than 30 percent of Earth's land surface and account for 50 percent of plant productivity. Therefore 45% of the carbon stored on land is tied up in forests. Further, these being the dominant terrestrial ecosystem, the forest account for 75% of the gross primary productivity of the Earth's biosphere and 80% of the plant biomass. Removing half the forest cover, will not only bring in an increase in the population of human beings and other living organisms but will also bring about increased pollution and a great ecological imbalance.

Floods are common in north India because of excessive deforestation in the catchment areas. Roots of the trees keep the soil together and drain the extra water into the underground water reservoir. Due to deforestation (cutting down of the trees), the soil is no longer able to hold or drain the excess water thus leading to floods. 

Deforestation is the cutting of trees which disturbs the equilibrium of a healthy environment. It increases the carbon dioxide content in the atmosphere and contributes to global warming. They produce oxygen and regulates the water cycle by releasing water vapour into the atmosphere. Without trees, forest lands can quickly become barren land. It also causes loss of wildlife, due to the loss of its habitat. Deforestation leads to famine (scarcity of food), flood, and drought as well as loosened soil causes soil erosion. Thus, the correct answer is option D.

Fossil fuels are non renewable conventional energy resources found inside earth's crust, where they have been formed through heat and compression on forests and other organic matter buried underneath due to earthquakes, landslides etc.

The popular 'Chipko Andolan' was started in 1973 in Gopeshwar, U.P. when forest trees were not allowed to be cut by village folk by hugging them first near village Mandal, then Rampur Phata and in 1974 near village Reni (led by Gaura Devi). The movement had two leaders, Chandi Prasad Bhatt of Gopeshwar and Sunder Lal Bahugana of Silyara in Tehri region.  A similar movement was undertaken by Paudurang Hegde in the south. It was known as Appiko movement. It's aim were uliso (conservation), belesu (growth-plantation) and balasu (rational use).

Solar energy is inexhaustible non-conventional resource. Its use is yet to pick up because of requirement of back up system to store and generate electricity during night and during cloudy days. There are three methods of harnessing solar energy- direct heating (e.g., solar cookers), thermoelectric conversion or solar thermal power plants, e.g., steam generation and photovoltaic conversion.

Renewable source of energy include biomass energy and some forms of inexhaustible energy like solar energy, hydropower, wind power, tidal energy, wave energy, geothermal energy etc.

Coal and oil are fossil fuels been derived from dead bodies of plants and animals, which existed in past. Hence, they are carbon compounds and emit carbon dioxide on combustion. Organic compounds are obviously compounds of carbon and will evolve carbon dioxide on combustion. Nuclear energy is non conventional, non renewable resource. Nuclear fission (now fusion also) of selected radioactive materials yields large amount of heat energy. For example one amu of Uranium - 235 yields energy equal to burning of 15 metric tonnes of coal. The energy released in nuclear fission and fusion is not due to combustion process and hence, does not evolves carbon dioxide.

Chipko Movement, started in 1970's, was a non violent movement, aimed at protection and conservation of trees and forests from being destroyed. The name of the Chipko moment originated from the word 'embrace' as the villagers used to hug the trees and protect them from wood cutters from cutting them.
