A hemp field

One hectare of hemp produces 25% more oxygen than one hectare of forest, ensuring an approximately double supply of cellulose. One hectare of hemp grows in 6 months. By manufacturing hemp paper we could save millions of hectares of forest every year. Hemp can be used in textile production, construction and even as biofuel. 😍
