#Marijuana/Hemp, Climate, CO2 and Airial RE-forestation.

Hemp can be used as a short term solution to the climate change challenge, simultaneously increasing soil carbon, locking carbon into raw materials and replacing unsustainable raw materials across several industries. It is an adaptable, hardy, multi-purpose crop that can play an important role in reducing and repairing human environmental damage.

Since accurate records began in 1850, atmospheric CO2 had increased from pre-industrial levels of 280 parts per million (ppm) to 360 ppm, by 2000. Emitted in a historically short period, this represents an enormous 42% increase of carbon dioxide in the atmosphere. An analysis of future global trends in greenhouse gas emissions has shown that if we continue at the present rate, by 2100 this figure will rise to 540-970 ppm. It is clear that the situation is serious and needs immediate attention Fossil fuel consumption and unsustainable land use conversions can be considered the most responsible for climate change. Around 80% of the CO2 being added to the atmosphere each year currently comes directly from the burning of natural gas, and coal and oil deposits. Combustion of fossil fuel releases their carbon content into the atmosphere as carbon dioxide gas (CO2), increasing the total quantity of CO2 in the atmosphere. Carbon dioxide has the capacity to trap energy from sunlight, the so-called 'Greenhouse Effect'

Hemp is far less vulnerable to changes in climate compared to slow to medium growth forests and still has the most useful biochemical characteristics of hardwood. In addition, hemp is a very versatile crop, not just in terms of use value, but also in terms of how it can be managed by farmers. Growing hemp on deforested hillsides prevent landslides, run-off and also prepares land for future crops or reforestation. Large scale tree planting is not feasible without providing an immediate and sustainable alternative to forest resources used by the majority of the worlds population for cooking heating and raw materials. Hemp produces several metric tons of versatile biomass per hectare annually or bi-annually in hotter climates, potentially protecting old growth forests.

Marijuana/Hemp grows virtually annywhere and actually improves the quality of the ground and prepares it for other plants to catch on... While protecting the ground from direct sunlight with its leaves that let thru enough light for young sprouts of any other seeds to develop over their 1st season...

Combine this with the idea of aerial reforestation as was recently shown on Discovery Channel and turn deforested areas of tropic rainforest into a source of food fibre and oils...
