In Internet hemp as a veritable miracle cure hyped, can save the people before the destruction of the environment and food problems. You should give the statements of Faith?
The production of hemp was banned in the United States, in 1937, the “Marihuana Tax Act”.
Including industrial hemp, a subspecies of the Cannabis sativa fell. Since the Plant contains little of the Tetrahydrocannabinol (THC), has no intoxicating effect. This Hanfart be attributed to the Internet instead, a variety of positive properties. You should have the potential to save us from environmental problems.

In the framework of a new agricultural law, the U.S. has allowed the government the production of these Hanfart 2018, so that farmers are allowed to grow the Plant well over a large area. But, this makes everything really revolutionize the textile industry to the construction industry?
Researchers suspect that a part of the hype of the hemp Lobby was triggered, not has it taken in the fight for the legalization of the Plant, with the science as accurate. However, studies also suggest that hemp could replace with the help of targeted investments, less sustainable materials.
Which statements are true and which are not?
Statement 1: hemp is the oldest Crop that was already cultivated 12,000 years ago.
Most of the finds indicate that people have started about 10,000 years ago, with plant breeding, and in Mesopotamia. However, there is little evidence that hemp was cultivated so early.
Hemp is rich in fatty acids, protein, and Omega.
The people and the hemp plant has a long history but actually. Archaeological finds suggest that it was already cultivated more than 4,000 years ago in China, from the fibers in paper, textiles, ropes, and from the seeds Oil.
Statement 2: hemp could find in 25,000 products.
Hemp is a versatile Plant, since different parts of the stem up to the flower – at least theoretically – can be used to “to Live and clothes to Wear,” says Lawrence B. Smart, Professor at the school of Integrative plant science Cornell University in the U.S. state of New York. He explores the potential of the cultivation of hemp has a large, industrial scale.
The Plant was also a valuable gluten – and soy-free source of protein, rich in Omega-3 and Omega-6 fatty acids, which occurs naturally in the otherwise mainly in fish. It is suitable therefore as a dietary Supplement for Vegans and as animal feed, adds Smart.
“I think that the statement of the multiple applicability, for example, the fibers or as a medical product, is right,” he says to DW. The question was whether the “cost is cheaper or better or more sustainable than the existing products that we currently use.”
Statement 3: biofuels from hemp could result in a green transport revolution
Hemp is a plant Energy: it can be used as biomass, because the Stalks are rich in cellulose, or Oil for biofuel. So they could complement other renewable energy sources. But, as with other energy crops, there are also problems in the large-scale cultivation. Although it is claimed that the Plant needs a little fertilizer, but for the large-scale cultivation of hemp monocultures much nitrogen is needed – similar to that of Corn.
The hemp seeds pressed Oil can be used for salad dressings and also as a biofuel.
“I do not believe that we have created the right life cycle assessments to be able to say that hemp biofuels have any advantages over the use of Corn,” says Smart. “Hemp produces a reasonable yield per hectares, but other crops are far more sustainable.”
Smart research group at Cornell University examined plants, a series of potential energy. So far, their research indicates that pasture, a perennial Plant, it could be sustainable as an annual Plant such as hemp. This is because pastures are planted only once, and the wood can then be periodically harvested without the need of the soil in the next 25 to 30 years edit. Each Time a field is planted or ploughed, are releasing carbon into the atmosphere.
Statement 4: hemp does not grow on nutrient-poor soils, pesticides are needed.
A widespread claim is that hemp grows in the reason alone. In fact, there are only few studies provide information about whether this is true, because in the 20th century. Century has not been grown hemp even on a large scale.
First smaller studies in Italy and the USA to promising results, for example, with regard to the ability of hemp to the floor in toxins to escape. Researchers also found that the Plant does not need to be treated, it is cultivated under the right conditions – because of their fast growth with herbicides to control pests to hold.
Hemp contains cannabinoids and terpenes, both of which are components, which can deter insects. But Smart warns that one should beware of claims that, therefore, no pesticides are needed.
Hemp may be less susceptible to pests than other plants. The Plant is cultivated, but large areas of mono-culture, will not remain without negative consequences for the environment.
“We have found a number of pests, the [hemp] damage, and some diseases, including new fungal species, which are currently being investigated,” says Smart. The laboratory for agricultural analytical services Pennsylvania State University have also found that pests, such as aphids, mildew and snails can cause damage to the Plant.

“If you are planting a small approximately 6 x 6 meters large garden, it is very unlikely that you will experience agents the full range of pests and disease, you would expect to approximately 8,000 acres,” adds Smart. Industrial agriculture, regardless of the Plant as a mono-culture, leads to environmental problems. It depends always how a Plant is grown.
Statement 5: hemp could replace plastics made from oil and the people could live in houses made of hemp
Companies such as Zeoform in Australia and Kanesis in Italy make bioplastic made of hemp in small quantities. At present, the production is complicated, energy-intensive and expensive, so that hemp plastic is to be used in the near future, no Alternative to the petroleum-based plastics.
However, hemp is today as a popular Alternative to glass fiber, for example, in highly compressed materials. So the car manufacturer, BMW, hemp for door panels. As a sustainable building material it is used.

The misleading Name “hemp concrete” is not a substitute for concrete, but the insulation for timber-framed houses. He is especially popular in France, although he is more expensive than conventional Alternatives. He had advantages, so Pete Walker, Professor at the faculty of civil engineering and architecture of Bath University in England.
“It is a renewable resource,” said Walker. “You can leave hemp in four months to grow, pulling carbon dioxide from the atmosphere and bind it in the plant material.” The breathable structure to regulate the temperature and humidity of a building and reducing energy consumption, he adds.
Statement 6: water consumption in the production of hemp is 25 to 50 percent lower than in the case of cotton.
Current comparative studies for cotton and hemp are hard to find. The Stockholm environment Institute, published in 2005, one of the most extensive reports and compared the two natural fibers with the synthetic fiber Polyester.
The study found that cotton needed within a growing season about 50% more water than hemp. Unlike hemp, cotton needs to be much watered more, and is often grown in water-poor regions such as Uzbekistan.

Claim 7: The US Constitution was written on hemp
The National Constitution Center in Philadelphia and the fact check website Politifact to disprove this scurrilous allegation that has been circulating on the Internet. The U.S. Constitution, the Declaration of independence and the Bill of Rights were all written on parchment, so, on animal skin.
The Constitution Center acknowledges, however, that the first drafts of these documents could be created on hemp paper, because the Plant was frequently cultivated in North America for the manufacture of ropes and sails. The founding father of USA, Thomas Jefferson, and also the country’s first President, George Washington, grew both hemp.
