Hemp is not demanding to cultivate, requiring little water, no pesticides, and absorbing a significant amount of carbon dioxide while producing oxygen. It grows rapidly and is rich in biomass, making it an excellent carbon sequestration option.
Hemp plastic is a lightweight, strong, and biodegradable renewable resource. It can replace many petrochemical plastics (oil-based plastics) and reduce the greenhouse effect by 'locking in' carbon. As hemp grows, it absorbs carbon dioxide and converts this pollutant into oxygen, which it then releases. When hemp is used for sustainable materials, the carbon dioxide stays locked in, preventing it from being released into the atmosphere and combating global warming.
Traditional plastic takes 450 years to decompose, never fully disintegrating in natural conditions. Hemp plastic, on the other hand, decomposes in about six months under proper conditions. Replacing conventional plastic with hemp plastic would positively impact the lives of wild animals and humans, reducing the threat of plastic pollution in our seas and oceans. Studies have shown that 60% of seabirds have plastic in their digestive systems, causing health disorders and shortening their lives. Microplastics have also been found in human blood, raising significant concerns about the health impacts on humans.

Hemp farming reduces water pollution
Hemp farming has been found to reduce water pollution. Hemp is a sustainable plant that requires less water than other crops, making it ideal for regions facing water scarcity. Its deep root system helps retain soil moisture, reducing the need for frequent irrigation. This not only conserves water resources but also minimises soil erosion where hemp is cultivated.
Hemp is also known to improve soil health. Its deep roots aerate the soil, enhance soil structure and fertility, and break up compacted soil, improving water penetration. Hemp's resilience to weather extremes, including droughts and very wet conditions, is likely due to its extensive root system, which can extend up to 3 feet deep. This enables the plant to access nutrients and water from deeper soil layers, reducing the need for irrigation.
Hemp farming typically involves fewer harmful chemicals compared to conventional agriculture, promoting safer working conditions and reducing chemical runoff into water bodies. Hemp is naturally resistant to insect pests and predators, reducing the need for insecticide applications. It also reduces the need for synthetic pesticides and fertilisers, further decreasing the risk of chemical pollution in water sources.
In addition to reducing water pollution on land, hemp is being explored as a solution for clearing polluted waters. An initiative in Florida, Hemp4Water, aims to use hemp to absorb nitrogen and phosphorus from local rivers and lakes, reducing toxic pollution and harmful algae blooms. The project involves creating 'mats' where hemp can be grown and added to the lakes, with the roots absorbing nitrogen underwater and the above-water parts absorbing carbon from the air.
Overall, hemp farming has been shown to reduce water pollution through its low water requirements, positive impact on soil health, reduced need for chemicals, and potential for water remediation.
