Forests provide many important raw materials from which we make various useful items. Many things which were earlier made from forest produce are now being made from synthetic fibers. For example; plastic chairs have replaced wooden chairs in a big way. Similarly, wooden cartons and crates have been replaced by plastic cartons and crates. The way plastic has replaced wood from many items, it is definitely minimizing the need to cut forests. Thus, it can be said that manufacturing synthetic fibers is actually helping conservation of forests.
Raw mateials for natural fibres are mainly derived from plants and this means cutting a lot of trees.this leads to deforestation.But raw materials of synthetic materials are mainly petrochemicals.Hence,manufacturing synthetic fibres really help in conserving forests
