Planting a Trillion Trees Can Curb Climate Change by 25%; According to Study

by | July 8, 2019

A new study suggests planting trees across the globe, covering an area equivalent to the size of the US, is the most effective solution to mitigate the bane of climate change or global warming. However, critics have touted the study as “too good to be true.”

Planting a Trillion Trees Can Curb Climate Change by 25%; According to Study

A new study published in the journal ‘Science’ has presented a bold claim – it is possible to counter the changes in climate dramatically by planting trees across the globe equivalent to the size of the United States, the Associated Press reports.

According to BBC, earlier estimations of the practical space available for planting trees globally didn’t give a clear cut assessment. Now, the study states as much as 25% Co2 can be reduced from the atmosphere following the suggestion. The authors of the study have claimed this method is “by far — by thousands of times — the cheapest climate change solution” in the world.

There are recommendations on the ideal area of tree cover (IPCC recommends 2.4bn acres); however, the problem of actually estimating how many trees the world can support was hard to come by, BBC reports.

The new study skips the loopholes and suggests specific spaces available for tree plantation, the number of trees to be grown, and their impact on carbon emission. Using sophisticated technology, the study found the world can still support another 0.9bn hectares (2.22bn acres) of tree cover. This area is excluding the already stationary trees, urban areas, farmland and so on. Lead author of the study, Jean-Francois Bastin, estimates another 1 trillion trees can be planted on Earth, Associated Press reports.

“Our study shows clearly that forest restoration is the best climate change solution available today and it provides hard evidence to justify the investment,” senior author of the study, Prof Tom Crowther stated, BBC reports. In the past, Crowther reportedly also suggested avoiding eating meat could be one of the effective ways to fight the menace.

However, critics are of different opinions. One critic from the University of Reading has denoted the study to be “too good to be true.” Another critic, a professor from the University of Oxford, stated restoration of trees may be among the most effective ways; nonetheless, it is “very far indeed from ‘the best climate change solution available,’ and a long way behind reducing fossil fuel emissions to net zero.”
