What if there were 1 trillion more trees? - Jean-François Bastin

Summary by Krater

This video explores how trees sequester carbon and whether planting a trillion trees could meaningfully combat climate change, concluding that while forests store significant carbon, ecosystem complexity and restoration challenges make it an incomplete solution.

From the video

Answers: Can planting trees solve climate change?

• tree carbon sequestration
• photosynthesis and respiration
• global tree restoration potential
• ecosystem complexity in reforestation

What it concludes

• Earth could support nearly 1 billion hectares of additional forest, totaling about 1.2 trillion new trees.
• Restored ecosystems could capture between 100 and 200 billion tons of carbon, accounting for over 1/6th of humanity's carbon emissions.
• More than half of the potential forest canopy for new restoration efforts can be found in just 6 countries.
• Ecosystem complexity and the risk of unintended consequences make large-scale reforestation a complex and challenging solution to climate change.
