Renewable source of energy is a type of resource which can be replenished back easily. Coal, petroleum, kerosene will take millions of years to replenish back so, they are non-renewable source of energy.

Inexhaustible resources are also called as renewable resources. These are present win abundance in the nature. They cannot be depleted or exhausted by human activity. Examples include water, sand and solar energy. Human energy is the greatest inexhaustible resource.

A non-renewable resource (also called as finite resource) is a resource, that does not renew itself at a sufficient rate for sustainable economic extraction. Non-renewable resources are resources, that are not easily replenished by the environment. Earth minerals and metal ores, fossil fuels (such as coal, petroleum, and natural gas), nuclear fuels, and groundwater in certain aquifers are all non-renewable resources.

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. Water is considered as the renewable form of energy. The water reserves can be replenished by the rainfall. The water resource is degradable form of resource. The contaminants and pollutants from the industries can degrade the quality of the water in the water bodies. 

Reforestation is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation. Reforestation can be used to rectify or improve the quality of human life by soaking up pollution and dust from the air, rebuild natural habitats and ecosystems, mitigate global warming since forests facilitate biosequestration of atmospheric carbon dioxide, and harvest for resources, particularly timber, but also non-timber forest products. Reforestation usually involves replanting areas of forest which have previously been damaged or destroyed, using native tree species. Sometimes forests are able to regenerate naturally if sufficient trees remain nearby and seeds can be dispersed into the deforested areas via animals or wind. However, areas of forest which have been severely degraded are unlikely to be able to regenerate naturally and need to be replanted by hand using native tree species.

According to global forest resource assessments, approximately 31% of the Earth's land area is covered by forests.

Plants remove carbon in the form of carbon dioxide from the atmosphere during the process of photosynthesis.

Deforestation removes the protective canopy and root systems that hold soil in place. This leads to increased soil erosion and can eventually turn fertile land into desert, a process known as desertification.

Deforestation is removal or deterioration of forest cover of an area. It results in shirking fuelwood, reduced timber, change in climate, soil erosion, flash floods, siltation, drought, loss of biodiversity, less rainfall, global warming etc.
