Ludwig acquired the project in 1967; it has been under way as a mining project for some 50 years prior to that. The Jarí project under Ludwig ultimately failed because of public outcry. The story doesn't tell us what kind of trees were planted (I would suspect eucalyptus, non-native to the area and not easily adaptable to a rainforest setting, though it is grown commercially with great success in more temperate zones of Brazil), but the main problem was the vast amounts of rainforest that had to be destroyed in order to build the cellulose pulp plants, the waste treatment operations, the railroads (which is what Dr Bill's link is really about) and all the other infrastructure necessary to maintain such an enterprise. In 1982 Ludwig finally sold out under pressure and the area is now used by a consortium of businesses. They're still growing trees (coals to Newcastle?), but in a less invasive way and to a much lesser extent. The project continues to be highly controversial.

Here's the link Dr Bill provided, if anyone is interested. The pictures tell the story of devastation, even if the text doesn't:

Now, then, back to words in English.
