Planting a Trillion Trees is Fastest, Cheapest Way to Reverse Climate Change: Study

Researchers have long warned of the dangers of climate change, which has seen ecological conditions degrade as weather patterns grow more unpredictable. And now, scientists are urging the world to plant billions of trees wherever possible as the cheapest and most effective way to handle the climate crisis.

According to the new study published in the journal Science, planting about a billion trees across the globe could remove two-thirds of all carbon dioxide emissions worldwide—approximately 25 percent of the CO2 in the atmosphere—creating a vast natural means to trap and store the emissions in an affordable and politically non-controversial manner.

 

The researchers say the Earth has room for over 1 trillion additional trees that can be planted in abandoned lots, woodlands and parks across the globe as part of a new worldwide planting initiative that would remove a large portion of heat-trapping emissions from the atmosphere.

Professor Thomas Crowther, a climate change ecologist at the Swiss Federal Institute of Technology in Zurich who led the research, told the Associated Press:

Crowther also stressed the urgency of taking action, given the devastating effects and rapid progress of climate change, noting that tree planting would have a near-immediate impact, since trees remove carbon at an early age.

The ecologist said:

Crowther’s laboratory used Google Earth mapping and data from the Global Forest Biodiversity Initiative to gain an accurate understanding of the current global tree count. The initiative relies on the efforts of ground-level volunteers, 1.2 million monitoring locations across the globe, satellite imagery, as well as tens of thousands of soil samples.

The information, paired with machine learning and artificial intelligence, allowed Crowther’s lab to identify a figure of three trillion trees on Earth—more than seven times the amount estimated by NASA.

It also gave Crowther’s team the ability to predict how many trees could feasibly be planted across the globe.

According to the study, an area of trees roughly the size of the United States could scrub 205 billion metric tons of carbon emissions—out of the roughly 300 billion metric tons of carbon pollution spewed into the atmosphere over the past 25 years.

The countries with the most available room for reforestation include Australia, Brazil, Canada, China, Russia, and the United States. According to the study’s lead author, Jean-Francois Bastin, there is space for at least 1 trillion more trees, and potentially 1.5 trillion on top of the 3 trillion trees on the planet.

Bastin said:

Unfortunately, not all governments appear willing to grow their forests. For example, Christian Poirier, Amazon Watch’s Program Director, told MintPress News that Brazil’s “Bolsonaro has overseen the most significant rollback of, and full-on assault on, human rights and environmental protection in Brazil since the fall of the country’s military dictatorship and the reinstallation of democracy in 1985.” The country has seen a sharp escalation in illegal logging and land theft since Bolsonaro came into power.

Tropical areas could enjoy total tree cover, while others would have sparser coverage—effectively meaning that on average, around half the globe would be under tree canopy.

Crowther told the Guardian:

The professor also stressed that it still remains crucial to halt deforestation and reverse greenhouse gas and carbon emissions to zero, if possible, while we still have the time. Crowther added:

But not all scientists are convinced by Crowther’s study. Martin Lukac, a professor from the University of Reading, remains skeptical, noting:

While Myles Allen, a professor of Geosystem Science at the University of Oxford, said:

Some groups have taken matters into their own hands, with or without supporting research. For example, as the Mind Unleashed previously reported, a Sikh initiative called The Million Tree Project aims to plant one million new trees throughout the world, with tens of thousands already having been planted.
