What are the downsides to GMOs?
Cons of GMO Crop Farming
- Cross-Pollination. The out crossing of GM crops to non-GM crops or related wild type species and the adventitious mixing of GM and non-GM crops has led to a variety of issues.
- Pest Resistance.
- Human Health.
- The Economy.
How do GMOs help farmers?
GMO crops that are tolerant to herbicides help farmers control weeds without damaging the crops. When farmers use these herbicide-tolerant crops they do not need to till the soil, which they normally do to get rid of weeds. This no-till planting helps to maintain soil health and lower fuel and labor use.
Are GMOs expensive for farmers?
GMO seeds are expensive and farmers must buy them each year or else be liable for patent infringement. And while contamination can happen through no fault of their own, farmers have been sued for “seed piracy” when unauthorized GMO crops show up in their fields. Patents make independent research on GMOs difficult.
Should GMOs be used?
Proponents of genetically modified organisms, or GMOs, say that farmers who grow these crops are able to use fewer environmentally damaging pesticides. And proponents say that numerous studies have shown that genetically modified foods are safe to eat. Critics, however, say the claims of those benefits are overblown.
Why do we need GMOs?
In summary, GMO crops can have remarkable environmental benefits. They allow farmers to produce more food with fewer inputs. They help us spare land, reduce deforestation, and promote and reduce chemical use.
What are three areas in society that GMOs are used?
In fact, there are over 4,200 uses of GMO field corn, including fuel for our cars, oil for sunscreen and water bottles, starch for magazine printing and sidewalk chalk.
What areas are GMOs used in?
GM crops made up 29% of the world’s maize produce, and almost a quarter of the world’s oilseed rape that year. Among the countries growing GM crops, the USA (70.9 Mha), Brazil (44.2 Mha), Argentina (24.5 Mha) India (11.6 Mha) and Canada (11 Mha) are the largest users.
