SKIMMING
Skim the following passage
Every second, one
hectare of the world's rainforest is destroyed. That's equivalent to two
football fields. An area the size of New York City is lost every day. In a
year, that adds up to 31 million hectares -- more than the land area of Poland.
This alarming rate of destruction has serious consequences for the environment;
scientists estimate, for example, that 137 species of plant, insect or animal
become extinct every day due to logging. In British Columbia, where, since
1990, thirteen rainforest valleys have been clearcut, 142 species of salmon
have already become extinct, and the habitats of grizzly bears, wolves and many
other creatures are threatened. Logging, however, provides jobs, profits, taxes
for the government and cheap products of all kinds for consumers, so the
government is reluctant to restrict or control it.
Much of Canada's forestry production goes towards making pulp and paper.
According to the Canadian Pulp and Paper Association, Canada supplies 34% of the
world's wood pulp and 49% of its newsprint paper. If these paper products could
be produced in some other way, Canadian forests could be preserved. Recently, a
possible alternative way of producing paper has been suggested by
agriculturalists and environmentalists: a plant called hemp.
Hemp has been cultivated by many cultures for thousands of years. It produces
fibre which can be made into paper, fuel, oils, textiles, food, and rope. For
centuries, it was essential to the economies of many countries because it was
used to make the ropes and cables used on sailing ships; colonial expansion and
the establishment of a world-wide trading network would not have been feasible
without hemp. Nowadays, ships' cables are usually made from wire or synthetic
fibres, but scientists are now suggesting that the cultivation of hemp should
be revived for the production of paper and pulp. According to its proponents,
four times as much paper can be produced from land using hemp rather than
trees, and many environmentalists believe that the large-scale cultivation of
hemp could reduce the pressure on Canada's forests.
However, there is a problem: hemp is illegal in many countries of the world.
This plant, so useful for fibre, rope, oil, fuel and textiles, is a species of cannabis,
related to the plant from which marijuana is produced. In the late 1930s, a
movement to ban the drug marijuana began to gather force, resulting in the
eventual banning of the cultivation not only of the plant used to produce the
drug, but also of the commercial fibre-producing hemp plant. Although both
George Washington and Thomas Jefferson grew hemp in large quantities on their
own land, any American growing the plant today would soon find himself in
prison -- despite the fact that marijuana cannot be produced from the hemp
plant, since it contains almost no THC (the active ingredient in the drug).
In recent years, two major movements for legalization have been gathering
strength. One group of activists believes that ALL cannabis should be legal --
both the hemp plant and the marijuana plant -- and that the use of the drug
marijuana should not be an offense. They argue that marijuana is not dangerous
or addictive, and that it is used by large numbers of people who are not
criminals but productive members of society. They also point out that marijuana
is less toxic than alcohol or tobacco. The other legalization movement is
concerned only with the hemp plant used to produce fibre; this group wants to
make it legal to cultivate the plant and sell the fibre for paper and pulp
production. This second group has had a major triumph recently: in 1997, Canada
legalized the farming of hemp for fibre. For the first time since 1938,
hundreds of farmers are planting this crop, and soon we can expect to see pulp
and paper produced from this new source.
(NOTE:
This activity was written before 2018, when Canada legalized the sale
of recreational marijuana.)
* Logging is destroying the rainforests.
* Canada is a major supplier of paper and pulp.
* Paper could be made from hemp instead of trees.
* It is illegal to grow hemp.
* Recently, many people have been working to legalize hemp.
