David Conhye Posted over 1 year ago Why won't the Global Climate Debate end. Deforestation greatly affects atmospheric and hydrological cycles, which are intimately a part of our weather systems, as well as soil and land erosion, and the loss of biodiversity, which induce many unforeseen affects. As easy as it may be to conceive, 46-58,000sq miles of forest are still lost annually to this day. Reports can be very misleading, the number of trees cut down may decrease, yet there are still far more cut down than are planted. Also, whilst trees may be planted, they take decades or even centuries to mature and reach the same volume as the forests that are cut down, therefore even if the same surface area was to be replenished, the actual volume would be no where near equivalent. Recent trends aggravate this issue, yet it's also worth considering the vast forests that rapidly declined as people went to war in wooden boats. A single of these wooden ships may have taken literally thousands of elderly trees each, and in places such as around the Mediterranean these forests have never recovered. This has all occurred in a relatively short amount of time. Within a millennia we have deforested far more land than we could hope to replenish in any short amount of time, for a start it takes a long time just for people to become aware of such issues. Many people plant trees across the world, yet often such efforts only prevent the spread of accumulating desertification which has already cost far more than their efforts. Spreading agriculture also continues to greatly impact such amiable endeavours. Imagine if the Earth were one of your lungs and the alveoli, representing the trees, were hacked down by a parasitic organism. This would cause great disturbances, and even if the alveoli were capable of growing back, such an impact would have a rippling effect that comes to surface in time. An absence of trees or tall plants is a characteristic of mass extinctions, ice ages and great floods. They certainly play a large role in the regulation of the climate.
