What can we do to prevent deforestation? Hearing all these devastating affects of deforestation certainly makes me shiver and hope we never have to meet such ends...but it's coming. In fifty years or so, when the Amazon's gone, we'll be introduced to the beginning. The Amazon rainforest is currently the host of half the world's species and is a ‘natural sink' for ozone. If complete and rapid destruction of the Amazon occurred, it would be irreversible. The key plant/animal interactions in its tropical forests can't be re-established, and there'd be significant reductions in precipitation, evapotranspiration, and cloudiness. The effects on species diversity and atmospheric chemistry would be cataclysmic. Such conclusions leave people to wonder what we can do about it...
