Carbon dioxide traps heat in the atmosphere and prevents it from being released into space. The resultant global warming causes enormous adverse effects, including anomalous weather conditions, droughts and rises in sea levels due to the melting of glaciers. Today, we have industries that give us process and products that have led to this unprecedented ecological crisis and worldwide destruction of the biological heritage that we should bequeath to our children, grandchildren, and future generations.Hemp is a plant grown for its straw, its seeds and for the oil produced by pressing the seeds. Hemp fibre is the strongest known natural fibre, which has been used extensively over the centuries for ropes, canvas and clothing, paper, plastic goods and string. It is an excellent material for insulation and its seeds and the oil they produce have extensive

uses in food and medicine, reputed to be the best-balanced source of essential fatty acids. During the last century the popularity of hemp receded, partly due to industrial developments in petroleum-based synthetic fibres, partly because of bans on production linked for example to it being grown for its recreational use as marijuana. The many uses of industrial hemp are increasingly recognised, but although there are still many restrictions, the opportunities are great.
