we need to have sequestered 7-9 billion tons of carbon a year for every year until the warming levels off
An acre of hemp captures between 10-15 tons of CO2 a year, put in hectares, 0.4 ha captures 10-15 tons of CO2 a year
So, 2 billion acres or, 810 million ha, is needed to keep carbon at current levels
1.5 billion hectares of the world’s desertified land [is to] be restored by 2030. This is the area the UN says could be rehabilitated
In acres thats 3.7 billion. That is 1 billion more than is needed for hemp to merely stabilize the warming. Only half of the 1.5 billion would even need to be hemp, to keep things “habitable”
