I’m really confused by this new trend of people being super aggressive about things that won’t matter at all. Why not spend the energy somewhere it might make a difference?
Unwillingness to do this arbitrary action you've chosen isn't unwillingness to do anything positive.
As for complaining, you started it. (Unless you're claiming the article itself is useless complaining when they could do something to help the problem, but "plant a tree" is not something that could help this problem.)
I don't understand why people are downvoting advice to plant trees. Are there so many anti-tree people out there? I'll bet they use toilet paper...but maybe not. All that paper and wood has to come from somewhere. Replace and replenish.
As the OP says, the Amazon is a unique ecosystem. It's an old-growth rainforest. Planting trees only creates new-growth forests that, while nice, are ecologically very different.
