Arthur T Knackerbracket has found the following story:
Large ecosystems, such as the Amazon rainforest, will collapse and disappear alarmingly quickly, once a crucial tipping point is reached, according to calculations based on real-world data.
Writing in Nature Communications, researchers from Bangor University, Southampton University and The School of Oriental & African Studies, University of London, reveal the speed at which ecosystems of different sizes will disappear, once they have reached a point beyond which they collapse -- transforming into an alternative ecosystem.
For example, once the 'point of no return' is reached, the iconic Amazon rainforest could shift to a savannah-type ecosystem with a mix of trees and grass within 50 years, according to the work.
Some scientists argue that many ecosystems are currently teetering on the edge of this precipice, with the fires and destruction both in the Amazon and in Australia.
"Unfortunately, what our paper reveals is that humanity needs to prepare for changes far sooner than expected," says joint lead author Dr Simon Willcock of Bangor University's School of Natural Sciences.
"These rapid changes to the world's largest and most iconic ecosystems would impact the benefits which they provide us with, including everything from food and materials, to the oxygen and water we need for life."

Are you not capable of not buying any of the products exported from the Amazon?

Do you have any idea how hard it is to avoid buying products that aren't problematic in some way? Normal people do not have 40 hours a week to research the impact of what they're doing is. It's a large part of why it's so important that governments set some sort of minimum standards on things like that. The labels themselves don't always differentiate between the way things were produced in a given country.

are you capable of understanding that a single person's purchasing habits, even if spotless, are not enough?
some of us actually don't buy palm oil or non-local meat because of exactly this issue (also in NZ for sheep, S.Am for several products, all sources of nonessential products which are costly in petroleum to make, and it'd be great if another Coltran source were found, etc)
and it's pretty clear to us that the world isn't magically following suit and acting sanely.

Speaking of understanding and acting sanely, go on boycotting palm oil to save the Amazon forest if you want to act insane or ignorant.
Because the facts are for the Amazon forest it's more like soybean oil instead of palm oil [1].
Somehow we hear fewer calls to boycott soybean oil to save the Amazon and its cute critters for some reason... Like maybe the US needs to sell soybean oil and it can't sell it as easily due to the trade war with China?
