Hemp grows very quickly and can be planted close together. Trees take significantly longer to grow and require much more space than hemp. A plot of land growing hemp therefore absorbs more carbon dioxide than almost any plant. Scientists estimate that for every ton of hemp grown, 1.63 tons of carbon dioxide is removed from the atmosphere. Plus, hemp crops can be grown in nearly any type of soil. They require very little water and don’t need any fertilizers or insecticides to stay healthy. And hemp begins sequestering carbon the moment it is seeded.
Growing more hemp crops would make a substantial positive impact on global warming. The rise in average temperatures on earth is caused by higher concentrations of greenhouse gases; specifically, an increase in carbon dioxide emissions. Carbon dioxide traps heat in the atmosphere and prevents it from being released into space. Warming temperatures cause negative effects including freak weather conditions, droughts and a rise in sea levels due to the melting of glaciers.
Hemp cultivation also encourages biodiversity in the soil, by regenerating farmland that has long been depleted from the use of toxic chemicals. Hemp is a “weed” and grows like one, ubiquitously, beating out other plants without pesticides; and its long tap root holds the soil, channeling moisture deeper into it. Unlike trees, hemp can be grown on existing agricultural land and included in a farm’s crop rotation. It improves the quality of the soil with positive effects on the yields and the profits from other rotated crops.
