In
the 1960s, a 'green revolution' produced bumper crops. Scientists
made new types of plants and pesticides to kill pests and insects.
This action is called genetic farming. Crops are designed to have
more chance for survival. These are some improvements to farmers,
but large food companies gain the most. Genetically modified plants
need fewer chemical sprays. Some people say that traditional ways
of growing are better.
One product, called "terminator" seed, is disease-resistant
and can produce bumper crops. Farmers must buy a supply every
year, because they grow only once. They cannot be harvested and
saved for future use.
Genetic
modified crops are big business. Europe buys up to 40% of the
U.S. soya bean crop, which is about 1/3 genetically changed. In
the world, $400 billion is spent on food every year. In 1995,
$450 billion was spent on genetically produced seed. It may grow
fifteen times or more by 2005.
Some people think that these super-plants are going to end old
ways of growing crops. Fruits and vegetables which are genetically
modified are on supermarket shelves. Experts believe that there
may be unknown dangers with them. Countries that do not like genetically
modified organisms include Switzerland, Austria, and Luxembourg.
In 1998, a scientist warned, "It's a risk that even the best
scientist cannot predict."
Genetic engineers plan to produce 'nutraceutical' products. That
means that they are a cross between genetic engineering and medicine.
An example of a product are tomatoes that protect against bowel
problems. Also, other vegetables will contain more vitamins.
PROS |
|
CONS |
|
| Genetically modified
plants have better chances of survival, and can be disease-resistant.
|
|
There might be dangers
to these crops. For example, if people eat disease-resistant
plants, the people might get the disease instead of the
plant.
|
| |
|
|
| These plants are almost
the same size, quality, and weight.

|
| The terminator seed
will make farmers' jobs easier because it is disease-resistant,
and can produce bumper crops.
|
|
These seeds only grow
once a year. Alias, farmers must buy a supply every year.
Also, these crops cannot be harvested and saved for future
use.

|
| Modified plants could
fight deadly diseases like cancer. Also, some of them are
suitable for vegetarians.
