Remarkable Ways Hemp Can Save the Planet

Not only can hemp help preserve our planet and improve our manufacturing, it can help fuel us forward and decrease our dependence on fossil fuels.
With the capability to produce vital resources such as rope, clothing, and paper, the hemp plant has played a crucial role throughout our history. Archeological evidence suggests that we’ve been using hemp since as early as 8,000 B.C., making it the first plant ever cultivated.

Alternative to Plastic

Every piece of plastic that has ever been made still exists in the world today. Plastic typically takes between 500 and 1,000 years to decompose in a landfill – water bottles take 450 years, fishing nets 600 years, and bags about 20 years. All of these products could end up in the ocean, harming marine life, and even our lives. Sahera Kaplan once stated that by 2050 there would be more plastic in the ocean than fish.


But, there is hope. Instead of using these plastic products that are destroying our planet, we could use hemp plastic products. Hemp is the greatest cellulose producer on earth, and it’s biodegradable. Hemp can form part of a biocomposite plastic whereby it’s either part of a totally organic mix or is mixed with a synthetic polymer. Studies have found hemp-based plastics to be 2.5 times stronger and five times stiffer than traditional plastic that is made from polypropylene.


It’s no surprise then that close to 100 years after Henry Ford made his first hemp car, many companies in the automobile industry are making use of hemp plastic. This car, made of hemp, was lighter than steel but could withstand ten times the impact without denting – impressive, right? Other products being made of hemp plastic include sunglasses, dog toys, and plastic bags.

Prevent Deforestation​

Hemp could potentially replace pretty much anything that is made from timber. Hemp is an incredibly valuable natural resource that is very underutilized. As one of the strongest fibres on the planet, using hemp for construction purposes will result in lighter and stronger wood products. Hemp is also able to hold nails better, and particle boards that are made of hemp are typically twice as strong as wood. Furthermore, just 1 acre of hemp will produce cellulose fibre pulp that is equal to 4 acres of trees, which means that hemp could quite easily and efficiently replace the majority of items that are made of wood.

Historically speaking, hemp was used to create many different products. In fact, the word “canvas” was derived from a Dutch word that means cannabis, which effectively means that real canvas was derived from hemp. Thousands of years ago, this magic plant was used to make all different kinds of commercial products such as textiles, rope, canvas, and paper.
There is a lot of potential for using hemp to prevent deforestation, promote sustainability, and save the lives of animals, and humans. The use of hemp gives us the opportunity to save natural resources, ensuring that we leave something behind for future generations. While it takes only around four months for hemp to be ready for commercial harvest, it takes trees between 20 to 50 years. Deforestation is increasing globally at a frightening rate. Researchers believe that the rate of deforestation is equal to the loss of 48 football fields every minute. It’s estimated that within a hundred years there will be no rainforests. This is one of the reasons that hemp is so valuable – it can replace trees as a source of raw material for paper and wood.

Hemp Can Feed the World

There are around 795 million people globally that are undernourished. In developing countries, 30 out of every 100 children will experience stunted growth because of lack of nutrition. But hemp could change all of this. Not only is it inexpensive, but it can be grown just about anywhere. Believe it or not, hemp seeds are thought to be the most nutritionally dense food source on the planet. Hemp seeds are a complete protein and provide the body with vitamins, amino acids, and much more.

Furthermore, hemp seeds could produce two of our most vital food products – flour and oil. They can also be eaten raw and added to routine meals, such as granola or cereals. Hemp seeds are very high in the natural oils that are required for good brain function and development, and they are safer than alternative choices such as fish, which could contain mercury and radiation. It is about time we return to our roots and realize the nutritional value of hemp.

Hemp Building Materials

Although it seems unlikely that entire houses can be built from hemp, it has become a reality thanks to hempcrete, which is a more sustainable alternative to concrete. Made from water, lime, and – of course – hemp, hempcrete has a negative carbon footprint, which means that more CO2 is absorbed by the hemp plant during cultivation that would be emitted during construction. Even more impressive, walls that are made of hempcrete will continue to absorb carbon dioxide throughout their lifetime. Essentially, this is a building material that just keeps giving back to the environment.

The same fibres that can be used to produce plastic can also produce a variety of eco-friendly alternatives that will help preserve the world’s natural resources:

Prevents Pesticide Pollution

Unlike flax or cotton – which have been estimated to consume 50% of all pesticides – hemp is naturally resistant to pests. This means that growing hemp doesn’t require any herbicides or pesticides.


When pesticides are sprayed onto the land, they can easily make their way into water sources such as oceans, rivers, or ponds. If pesticides contaminate the water, they could easily harm the living creatures in that water or anyone who ingests it. Even scarier, pesticides have been linked to birth defects, ADHD, and Alzheimer’s, to name a few diseases. So pesticides aren’t only dangerous to the environment, but are also hazardous to our health.

Soil Decontamination

One of the most impressive qualities of hemp is that it clean up pollution. So while our modern industries pollute, hemp has the opposite effect. Hemp has the potential to remove radioactive toxins and heavy metals from polluted soil. This is done through a process known as phytoremediation, whereby contaminants are absorbed through the fast-growing roots of the hemp plant that stores or sometimes even transforms toxins into other harmless substances.

An Italian study that was published in Plant and Soil in 2003 found that hemp had the ability to absorb nickel, chromium, and cadmium from soil, and also that high concentrations of the heavy metals had a very little effect on plant morphology. Hemp can grow in a variety of soil types and terrains. It forms deep roots which help to hold the soil together, which also helps to prevent soil erosion.

Hemp also increases the microbial contents of the soil, and its leaves and stems are rich in nutrients. After harvesting has taken place, these can be returned to the soil which will rejuvenate it for a richer yield the following year.

It’s time that hemp regained its place as of the most sustainable and versatile crops on the planet. As Jack Herer is famously quoted, “I’m not sure that hemp will save the planet… but I know it’s the only thing that can.” It’s time we let the hemp revolution take place if we really want to change the world that we currently live in.

The many usages of hemp

Hemp Can Save the Earth from Pollution

More and more farmers are now turning to hemp in their efforts reclaim their soil. For instance, in Taranto, Italy, a region known for their fine cheeses, has experimented with growing hemp to reclaim their contaminated soil. In 2016, the livestock in the region has been contaminated with dangerous toxins as a result of eating the grasses that were grown from the soil that’s been contaminated with lead and nickel. Their experiment of growing hemp has been successful. In only five years, 100 farmers have decided to plant hemp in a 300-hectare land area. And although they can only sell the hemp fibers for now because the edible parts are toxic, each crop has made their soil cleaner and toxic-free.

Hemp Soil Remediation and the Chernobyl Disaster

One of the most significant demonstrations on the use of industrial hemp was during the Chernobyl disaster. This nuclear disaster took place in 1986 and spewed radioactive wastes across the eastern part of Europe. During the late 1990s, a company decided to experiment with industrial hemp by growing the plant in some of the affected regions. The results are truly promising. According to the scientists, hemp is no doubt one of the best phytoremediation plants that they have discovered. Phytoremediation has also helped remove the radioactive elements present in water and soil, especially at the weapon-producing facilities in the area.

Eco-Friendly & Sutainable-Fuel

Not only can hemp help preserve our planet and improve our manufacturing, it can help fuel us forward and decrease our dependence on fossil fuels.

Although the hemp plants that were grown near the Chernobyl area cannot be made into medicine or food, these plants can be safely distilled to become ethanol and used as biofuel.

For instance, Belarus has conducted several experiments in growing hemp at contaminated soil to be used as fuel later on. By using hemp in creating biofuels such as ethanol, scientists believe that they will be able to take advantage of the hemp’s ability to remove contaminants from the soil. When growing hemp, the contaminants are removed from the soil and are trapped in the plants. Once the crop cycle is completed, the contaminants are entirely removed from the soil.

According to the National Hemp Association, hemp can be used to produce two types of fuels:

  • Biodiesel — produced from the oil of the pressed hemp seed
  • Ethanol/Methanol — produced from the fermented hemp stalk.

With the increasing problems surrounding traditional fossil fuels and oils, the need for a natural alternative is stronger than ever.
Hemp is the only alternative fuel that can run in any unmodified diesel engine, and provides a solution that is more efficient, more affordable, and most importantly, more sustainable than traditional fuel.
