Funding is available for this: governments are increasingly investing in ecosystem restoration both within their countries and abroad (e.g. the Bonn Challenge commitments), but we will not get near to what is needed without the financial firepower of companies. I believe companies should be encouraged to purchase carbon offsets to assist with forest protection and…This article was originally published on Mongabay Läs mer
