More trees could be solution to climate change
A new report from the ETH Zurich federal polytechnic is causing a stir in environmental circles.
Scientists say planting billions of trees would have a major positive impact on climate change – and it’s the easiest and cheapest method. Trees could remove two thirds of carbon dioxide created by humans.
The research team called the results ‘mind-blowing’.
They’ve identified 1.7bn hectares of currently treeless land that could be used without encroaching on urban or crop growing areas. The size is equivalent to the US and China combined.
But they also warn the findings are not a get out of jail free card. Carbon emissions still need to be cut back and it will take between 50 and 100 years for the new trees to reach their maximum carbon removal potential.
