In this article we will discuss several hemp benefits, everyone is aware of the climate crisis facing our planet. Many of us make decisions in our everyday lives to try and minimise our impact on the world whether that be through eating less meat, recycling or walking instead of driving. Bits very nature, when you choose to take CBD as part of your everyday life you are creating the pathway for more hemp to be grown across the world.  This is great news as hemp has a number of climate benefits.

What is hemp?

Hemp is from the same species of plant as cannabis. Unlike cannabis, it doesn’t get you high because it contains very low levels of the cannabinoid THC; less than 0.3% in the USA and 0.2% in the UK.  It is grown for industrial and medicinal use. Hemp fibre can be used for textiles, biomass fuel and paper. CBD products is often  derived from hemp plants because of their naturally low THC content. Hemp has been used for millennia around the world.

Hemp absorbs CO2

Of course, all plants absorb CO2 but hemp is special because of the amount of CO2 it absorbs compared to other plants. Some estimates reckon that hemp can absorb up to 15 tonnes of CO2 per hectare. For every tonne of hemp produced, 1.63 tonnes of carbon are removed from the air[1]. These CO2 absorbing powers are great news for the planet. As hemp takes in CO2 it releases oxygen.

Hemp Benefits the Soil

Hemp benefits the soil in three main ways: it cleans it, regenerates it and prevents soil erosion.

Hemp has an unparalleled ability to clean soil by absorbing pollutants. It does this through a process called phytoremediation. Other plants absorb pollutants from the soil and release them back into the air through their leaves. Hemp traps pollutants in its leaves until it dies. This explains why you want to make sure you take organic CBD because the soil it’s grown in won’t contain any toxins.

The phytoremediation of hemp makes it brilliant at regenerating soil. It can absorb heavy metals and toxins from the soil leaving it clean for other crops. Hemp is so good at this that after the Chernobyl nuclear disaster in 1986 it was planted in the soil to remove the radiation pollution. Hemp increases the microbial content of the soil where it grows and the stem and leaves can be left in the fields to fertilise the soil. Any crops grown next benefit from the clean,  nutrient-rich soil.

Soil erosion is a significant problem for farmers all over the world and as we have to feed the planet’s growing population we need to have as much fertile land for crops as possible. Hemp grows very deep roots that can reach up to nine feet below the surface. These roots break up soil compaction and increase nutrient absorption. They help to prevent soil erosion and this makes hemp a great rotation crop that can be used between growing other things.

Hemp doesn’t need much water                  

Hemp is often used for the same purposes as cotton. Things like clothing and rope can be made from both crops. However, it is estimated that hemp requires 50% less water than cotton. One study by the Stockholm Environment Institute found that cotton requires 9,758 kg of water per kg, while hemp requires between 2,401 and 3,401 of water per kg[2]. they also found that it is possible to make three times the amount of hemp fibre as cotton from the same amount of land. Hemp is very versatile and can grow in lots of different climates, this means it grows in places that naturally experience rainfall and doesn’t require watering from precious water supplies.

Hemp uses few pesticides

According to the Canadian Hemp Trade Alliance, hemp can be grown without any pesticides[3]. Hemp is naturally resistant to most insects and predators. This is great news for other plants and wildlife. Pesticides are used to kill insects and weeds that could potentially harm crops. However, they also kill very important insects like bees that are essential for the survival of plants. Pesticides can also wash off the soil into water sources and cause contamination. It’s important that hemp grown for CBD products is not exposed to pesticides. This is because hemp plants would store this in their leaves and it could end up in the CBD products themselves.

Summary: Hemp’s Climate Benefits

CBD is a natural product often made from hemp. Hemp is a plant that is not significantly damaging to the environment. It promotes healthy soil and can be grown with minimal use of pesticides. It absorbs CO2 at a greater rate than some other plants and it doesn’t need as much water as cotton. Hemp fibre is likely to become more popular for making clothes and it’s even being considered as a potential biofuel because of its climate benefits.
