Renewable - Eg.: RD o TH

Resources are components of the environment with intrinsic value, categorized as renewable, non-renewable, continuous, or extrinsic. Forests are vital resources that provide commercial products and essential ecological services, covering about one-third of the world's land area, with significant concerns regarding their declining cover. They contribute to oxygen production, carbon dioxide reduction, wildlife habitats, hydrological regulation, and soil conservation.

Any component of the environment, which has intrinsic value of its own is called as resource.

Any
component which can be transferred in a way such that it becomes more valuable and useful is termed as
resource.
Renewable - Eg. Clean air, clean water
Considered to be renewable with considerable lifespan -as long as they have the capacity to renew – unless
they are affected by catastrophes or anthropogenic activity
Non renewable - Eg. Groundwater, minerals
Available only infinite quantity their rate of renewal is so slow that they are considered as non-renewable
Continuous – Eg. Solar energy, wind energy
Considered to be available always
Extrinsic – Eg. - Human skills
FOREST RESOURCES:
Forests are one of the most important resources of the world. Apart from having high commercial
importance they provide high environmental services also. They act as a blanket on the surface of the earth.
Around 1/3 rd of world land area was found to be forests. 1/5 th of world forests were found in Brazil
and 6-7% was in Canada and USA. But the matter under high concern is the declination of forest cover year
by year.
USES OF FOREST
Commercial uses: Forests provide timber, fire wood, food material, resin, gum, non edible oils,
drugs, medicine, rubber, fibers, bamboo and many other important items.
Ecological uses:
1. Production of Oxygen: Photosynthesis – earth’s lungs
2. Reducing global warming – sink for carbon dioxide
3. Wild life habitat – 7 million species in tropical forests alone
4. Regulation of hydrological cycle– prevent surface run off – giant sponges – 50-80% moisture
5. Soil conservation – hold solid particles tightly and prevent soil erosion – wind breaks
