How to learn tree plantation

 Tree Plantation

Answer:

Tree plantation means planting trees at a large scale in a planned way.Trees are our friends .They give us shade and soothe our eyes with their green colour. They give us various kinds of frutis.They give us firewood as fuel for cooking.They give us timber for furniture,doors and windows,boats,electric poles,railway slippers,etc.

They give us rubber,too.Trees take in carbondioxide and produce oxygen.Sufficient trees cause sufficient rainfall and prevent draught. Trees along the roadside and coastal areas prevent erosion and tidal bore.But many inconsiderate people are cutting down trees at random for their selg-interest.So we are losing trees.Hence tree plantation must be taken as a project.

The more we plant tree,the more our environment will be balanced and greener.In Bangladesh ,tree plantation is compulsory because we have not so much forest as we require to maintain the ecological balance.Making the people conscious of it by holding various seminars and meetings,tree plantation campaign may be successful.

The mass media like TV and redio can play great roles to inspire people for tree plantation.To make life safe and sound ,there is no alternative to tree plantation.
