Over the past hundred years our food supply has greatly improved through traditional . Now we are beginning to the first fruits of the harvests. is moving fast and many people find it hard to decide whether plants are .
In some tests thousands of are analyzed and compared based on their and composition. Other tests make use of rather than comparisons between GM and non GM food. This way it is possible to see to what extent foods vary in their composition. -resistant and spray tolerant crops, for example, have been approved this way to make food for us to eat.
Environmentalists have three main concerns. The GM crops will create and or reduce , but above all, they worry about the of GM crop releases.
In the open pollen from crops could pollinate another related plant. If they with their relatives, there could be the danger of creating . And if they with non GM crops on farms for examples, the farmers could not .
The first commercial products of genetic engineering were . It’s mainly the that the benefits. Now in Europe and many other parts of the world are developing new products designed to be of direct benefit to the . Many of these research advances will be used in where there are potentially large enough markets for the new products.
For priorities depend on and are often a question of rather than . Areas and active research include plants that are resistant to high content in the soil or to . Great efforts are going into creating foods designed to be positively good for you. For example, tests are under way on a GM designed to increase levels of in the human body.
