Despite international efforts, the loss of tropical primary forests persisted over the past decade. In conventional afforestation techniques, 1 meter of growth per year is considered the norm. During years of researching on the ground in rainforests, Houlihan has seen how the building of roads and bridges, pitched as an infrastructure gain to local communities, are usually for the benefit of companies and governments often foreign companies and governments to mine, extract and poach valuable resources.

The leachability of metals is several orders of magnitude below regulatory limits. We are watching our planets rainforests disappear right before our eyes, and acting now is imperative to protecting the rest of our rainforests and the communities of people living within them.
