What are the disadvantages of the GM crops?

Perceived disadvantages of genetically modified crops may be grouped into five categories: 1) potential impact on non-target species; 2) potential for increased weediness; 3) increase in toxin levels in the soil; 4) exchange of genetic material between the transgenic crop and related plant species; and 5) selection for …

How has GM affected Africa?

Many African countries have banned GM crops, arguing that they will cross contaminate other plants, pollute the environment and could have long-term health effects for humans. Zimbabwe, for instance, says although GM crops may initially be resistant to pests, the resistance could breakdown over time.

What are some problems with GM crops?

Issues of concern include: the capability of the GMO to escape and potentially introduce the engineered genes into wild populations; the persistence of the gene after the GMO has been harvested; the susceptibility of non-target organisms (e.g. insects which are not pests) to the gene product; the stability of the gene; …

What are the dangers of genetically modified crops?

GM crops also manufacture their own pesticides, which puts further poisons into humans and soil and may cause unforeseen changes in the environment. Another concern is that toxins contained in the GMO plants may harm other organisms, such as monarch caterpillars, bees and birds.

Why do people support GMOs?

Five Good Reasons to Support GMOs GMOs are tested for safety and allergen potential before they go to market. In fact, GM food products are among the most tested products in history. Biotechnology can be used to make foods more nutritious. GMOs can actually reduce pesticide use. GMOs may be our best bet to adapt to changing global conditions.

Why should we use GMOs?

According to the GMO industry, there are many good reasons to use GMOs: Reduced need for herbicides. Reduced need of pesticides. Reduced greenhouse emissions as GMOs require less tillage or plowing, thus less use of fossil fuels.
