Ultimately, says Houlihan, ecological tipping points beyond which ecosystems like rainforests will collapse have been predicted for decades; it is a matter of global security and resilience that we save them. Particularly as rainforests contain scientific insights that are being lost before they can even be revealed. 2022-07-19 Symposium: Tropical Restoration-Reforestation Pros and Cons The goal of this symposium is to present some of the topics and debates connected to tropical restoration and reforestation, to help sharpen our thinking about what works under what conditions, and why. 80%, 87%, 64% and 48% of Cu, Cd, Pb and Cr were removed by 0.8% rhamnolipid after 12 h at pH 7.0.
