The Amazon has been facing deforestation efforts for decades. This is mostly due to their attempt to clear the land for farming. The current leader of Brazil has nothing to do with it. If you want to stop it, stop buying food from South America.
On a side note, Bolsonaro was only elected because Brazil has gone so far to the left that people have become sick of SJWs. For example, Feminists convinced politicians into abandoning the University entrance exam, the Enem, because it was somehow "unfair" Despite the fact that the topic was "The persistence of violence against women in Brazilian society", a topic near and dear to the Feminist cause. Most failed it because they failed to answer in a coherent manner, frequently using hashtags, misspelling words and catchphrases that didn't apply or make sense.
