Researchers have listed a set of ‘tipping points’ we are in danger of passing in a near future. Even small human induced climate changes could push these vital parts of the planet over the edge. These tipping points have been described as Earth’s ”Achilles heels” as they represent areas whose condition decisively affects the entire planet. Further environmental impact on these “vital organs” of the planet could have large-scale and irreversible effects on the global environment.
