At a conference I attended,we had to imagine what would happen if we didn't have enough water.One person said that we take water for granted and need to learn to respect the gift of water.The fact is that we could not live without water and the same could be said for trees.In our interconnected world,what we do to our trees affects our water,other species and us.Trees help humans in more ways than one.They reduce air pollution and global warming through respiration and removing particulate matter.They taken in Carbon dioxide and give out Oxygen that sustains life.Trees play an important role in maintaining a moderate climate by lowering air temperature.They provide shade and conserve energy.They help to reduce noise pollution.Besides,providing shelter and food for generations of birds and wildlife they reduce soil erosion too.Trees have been providing the wood required for various purposes from firewood to building huge structures.Trees attract rain-bearing clouds.In countries where agriculture is the main occupation,these are heavily dependent on the rains for water.Many trees provide us with medicinal products such as quinine and eucalyptus oil.In fact,many medicines that we ultimately use come to us through trees and vegetation.Would we prefer a life that is colorless and boring or one that is vibrant,cool and healthy.I think most of us would choose the second option.Then can we imagine a Life without Trees?
