There are several economically viable solutions, but Brazilian government should be interested in pursuing them, rather than only pursuing things that only benefits the current friends of the government (such as deforestation).
US/EU/etc forcing Brazil to get its shit together would be BETTER for the population. We don't need the deforestation to progress. Quite the opposite.
If Brazil were to wage a war on another country, would it be fine just because Europe/US also did it in the past?
