Hemp vs Cotton: The Ultimate Showdown | Collective-Evolution
Some other important facts
-Environmentally, hemp is a safer crop to grow than cotton. Cotton is a soil-damaging crop and needs a great deal of fertilizers, herbicides and pesticides.[xliii]
-Cotton crops in the USA occupy 1% of the country’s farmland but use 50% of all pesticides. [xliv] "The pesticides used on cotton, whether in the U.S. or oversees, are some of the most hazardous available today," says Doug Murray, Ph.D., a professor of sociology at Colorado State University who has studied pesticide use on cotton overseas.
-1 acre of hemp will produce as much as 2-3 acres of cotton.
-Hemp is 4 times warmer than cotton, 4 times more water absorbent, has 3 times the tensile strength of cotton.
It is also many times more durable and is flame ......ant.
-Many high fashion clothing manufacturers have produced clothes and footwear made with hemp. Some of these include: Nike, Converse, Armani, Patagonia, Polo Ralph Lauren, Oscar de la Renta and many more.
-Hemp fabrics were once far more expensive than cotton and other fabrics due to limited supply, but increased demand and availability in recent years have lowered the price considerably.
-Hemp breathes well and wicks moisture away from the body better than cotton.
-HT Naturals (Canada’s largest hemp t-shirt supplier) asserts that selecting their hemp/cotton blended t-shirt over an all-cotton t-shirt saves the environment 744 gallons of water. This company has recently partnered with Canada’s National Research Council to create Crailar an enzyme that will make hemp fibres as soft as cotton.
BTW...the first pair of Levis 1853...you guessed it...Hemp!
