SST. Class 4. Our Natural Resources- Forests

1.Coal and petroleum are non -renewable resources because they are limited and reduce in quantity as they are used.
2.Forests are large areas of land thickly covered with trees. They are useful to us in the following ways:-
a) Trees and plants give us the oxygen we need to breathe.
b) The roots of the trees prevent the soil from being washed away.
c) They provide us with food , fruits,timber, medicines etc.
d) Forests provide shelter to animals and birds.
3.Evergreen forests are green throughout the year. The trees here are tall and do not shed their leaves at the same time. They are found in areas with heavy rainfall such as Western Ghats, North East India and Andaman and Nicobar Islands . Trees found here are :- rosewood, ebony and mahagony.
4.Deforestation leads to soil getting washed away , floods and landslides . There is less rainfall and less oxygen for us to breathe. Many animals , birds and people lose their homes when forests are cut down.
5.Wildlife sanctuaries are set up to protect wildlife . We have a large variety of animals and they are hunted by us for their skin ,fur ,horn and tusks. So the government has set up Sanctuaries to protect animals and forests.
