In 2018, a report by the Intergovernmental Panel on Climate Change stated: If the world wants to curb global warming, we will have to grow at least 1 billion hectares of forest. It is an area equal to the United States that you see on the map.
Sounds like an impossible task? But no, a new report published in Science shows that the goal is completely achievable. Regardless of the area of agricultural land, the city and the current forest volume, the Earth can still plan 0.9 billion hectares more.
This area allows us to grow 1-1.5 trillion trees. This amount of plants can store up to 205 gigatons of carbon, about two-thirds of the amount of carbon that humans have emitted into the atmosphere since the 1800s until now.
"Planting is the simplest way to deal with climate change. And that is also the most effective solution"Research author Thomas Crowther, an ecologist from the Swiss Federal Institute of Technology, said.
Earth still has room for 1 trillion trees, if planted enough we will prevent climate change
"Forests are one of our largest natural allies in the fight against climate change", Laura Duncanson, a carbon reserve researcher working for the University of Maryland and NASA said.
The special report of the Intergovernmental Panel on Climate Change (IPCC) argues that if one billion hectares of forest can be planted, we will prevent global temperatures from increasing by 1.5 degrees Celsius by 2050.
Crowther and Jean-Francois Bastin, another ecologist from ETH-Zurich University, Switzerland, decided to find out if this goal is feasible. They analyzed about 80,000 satellite images to identify areas on Earth that could support the development of different types of forests.
They then subtracted the existing forests, agricultural areas and urban areas to determine the remaining vacant land. As a result, we have a land fund of up to 3.5 million square miles, equivalent to 9 million square kilometers to grow more forests.
It allows 1-1.5 trillion trees to grow to adulthood. That's a significant number compared to 3 trillion trees still on Earth. More than half of this vacant land is located in 6 countries: Russia, USA, Canada, Australia, Brazil and China.
The results show that IPCC forest restoration objectives are certain "kCompetition in current climate conditions"The authors wrote in the article. However, we must act quickly, because the pace of climate change has not yet stopped.
The Earth is still in a warming orbit. Without planting more forest right now, the land for greenery will reduce 223 million hectares, equivalent to nearly a quarter in 2050.
