Those are just two of many aspects affecting the number of remaining trees in the world. In addition to releasing oxygen and capturing CO2, thus fighting climate change, trees also filter air pollutants, prevent mudslides and erosion, gather and purify water, protect us from extreme weather conditions and cool down urban areas. They are paramount to life and take time to grow, two factors making them a very precious resource.
Replanting trees — a process known as reforestation — is a long and complicated endeavor, as it is mostly done by hand. An important component of land restoration, reforestation helps recover degraded soils, rebuild damaged ecosystems and protect biodiversity. As governments on a global scale look to cut their carbon dioxide emissions and years of monoculture farming leave soils depleted of minerals and nutrients, restoration has become an economic matter as much as an environmental one. In fact, the restoration economy is growing, attracting at least $2 billions in private capital per year. New companies are entering the market, introducing technologies to restore land more quickly and effectively and attracting consistent investments.
