Many countries in Europe, for example, have already destroyed majority of their forests. Not saying that destroying forests is good, quite the opposite, but unfortunately that's how it seems to go if you can't monetize the forests in some way and that's where western (and other) money could help.
They replaced forest that were destroyed. Planting new forest is great,but not as great if we had the old forest were still there. Once you lose biodiversity, it is gone forever.
Canada has (temperate) rain forest on Vancouver Island. It is also under more or less constant threat of being cut down, some of it already has but a lot of it still standing. If you happen to be in the area it is more than worth taking a hike through Carmanah [1] for a real life Lothlorien/Middle Earth experience.
