CBD is derived from the hemp plant. Hemp is a very sustainable plant because it does not require big amounts of water and pesticides to grow. Hemp has been used for thousands of years, and can be refined into a variety of commercial items, including textiles, biodegradable plastics, biofuel, and food. Hemp can also be derived in food, as a vegan source of protein. For example, hemp seeds or hemp milk are a great alternative to dairy and animal protein, which have a huge carbon footprint.
