We really do need to address it quickly one other things that scientists have discovered is that in a healthy ecosystem a diversity of thing are going on among different species and that leads to production up biomass that’s one measurement the scientist have able to make a healthy ecosystem tends to produce more biomass then I’ll less healthy ecosystem with more biomass you have a more stable foundation to support more organisms with in that ecosystem and you’re also sequestering more carbon that might otherwise add to climate change so higher biomass in an ecosystem is regarded as a good thing at least in term of a simple measure
