Sounds like Brazil's problem. Maybe they would be best pursuing policies that make deforestation in their country not worth the effort.
On the other hand, when timber is treated as a renewable cash crop, as it is in America and elsewhere, there's no money in deforestation without replanting.
One motivation for clearing those rain forests is that American Beef has gotten so expensive (because of corn prices) that we cannot compete for export. And places like Brazil are filling the vacuum.. IN FACT --- the fast food industry in the US is IMPORTING more and more "rainforest beef" every year..
Gee THANKS enviro-nuts.... ANOTHER unintended consequence of your "plans"??
Would you care to explain how US environmentalists are responsible for Brazilian clear cutting in favor of raising cattle?
And as far as corn and cattle feed:
Different cattle feeding production systems have separate advantages and disadvantages. Most cows have a diet that is composed of at least some forage (grass, legumes, or silage). In fact most beef cattle are raised on pasture from birth in the spring until autumn (7 to 9 months).[citation needed]Then for pasture-fed animals, grass is the forage that composes all or at least the great majority of their diet. Cattle fattened in feedlots are fed small amounts of hay or straw supplemented with grain, soy and other ingredients in order to increase the energy density of the diet. The debate is whether cattle should be raised on diets primarily composed of pasture (grass) or a concentrated diet of grain, soy, corn and other supplements. The issue is often complicated by the political interests and confusion between labels such as "free range", "organic", or "natural". Cattle raised on a primarily forage diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. However, the term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.

You really don't KNOW that much of the rainforest destruction is to clear land for McDonalds? What kind of environmentalist are you? I can't fill all the gaps in what you know. Go look up rainforest beef Brazil
Our cattle industry AND the rainforests are DIRECT VICTIMS of enviro MADNESS driven by your minions of morons pushing for biofuels..
