Q4: Give reasons:
(i) The rain forests are depleting.
(ii) Paddy is grown in the Ganga-Brahmaputra plains.
View Answer
Ans:
(i) It is true that rain forests are depleting. The various reasons for their depletion are –
- Developmental activities have started in a big way, resulting in the cutting of rain- forests for various purposes.
- Indigenous populations of rain-forests have been driven out who practiced conservation activities of forests and wild life.
- Industries are being set up after clearing the forests.
- Lumbering activities have also caused depletion of forests.
- Top soil is washed away during rains and lush green forests turn into barren lands.
(ii) The reasons are –
- Deep loamy soil is found in these plains due to the deposition of silt by the rivers for thousands of years.
- Rivers during floods spread new layer of alluvial soil every year. Hence, it does not require adding manure and paddy can be grown easily.
- Canals from rivers supply ample water for irrigation of paddy fields during dry season. So, there is no scarcity of water.
- The lower portion of the plains receives adequate rainfall which is very helpful for the cultivation of paddy.
- Cheap labour is available from the densely populated plains.
- Adequate means of transportation are there to raise and movement of paddy to the nearby markets.
- New technologies are being adopted by the farmers because they can afford it due to their sound financial position.
