(a) We must conserve our forests for the following reason:
(i) Forests produce a large number of products of commercial use such as timber, raw materials for the manufacture of paper, bidi leaves, sums, resins, essential oils. Thus, forests helps in economic development.
(ii)One of the main aims of conservutions is to try and preserve the biodiversity we have inherited because loss of biodiversity may lead to a loss of ecological stability.
(b) Two causes of deforestation are:
(i) Indiscriminate felling (i.e., cutting) of trees for the purpose of timber, fuel and individual demand of wood.
(ii) Overgrazing by a large livestock population.
