GM FOOD

GENETICALLY MODIFIED FOOD

 
 
1.Context
Genetically modified food remains controversial, especially in Europe, but for some experts it is the best science-based method for a sustainable global food system amidst biodiversity loss and a rising population.
Producing food is terrible for the environment. According to the online scientific publication Our World in Data, agriculture is responsible for a quarter of the carbon emissions in the atmosphere and the vast majority of world’s biodiversity losses.
 
2.What is GM Food?
  • Genetically modified organisms (GMOs) are organisms that have altered DNA to change their properties
  • Genetically modified crops can improve yield, build resistances to pests, frost or drought, or add nutrients
  • Crops can also be modified to reduce carbon emissions and boost the sustainability of food production
  • While widespread, GM crop production uses only about 10% of the land non-GM crop production uses.
  • GM is nothing more than a breeding technique, much like crossing that we’ve been doing for thousands of years. But it’s more sophisticated, so we can make very precise changes, very rapidly
  • GMOs were first introduced in the US in 1994, with modified tomato plants that ripened more slowly to prolong their shelf life
  • Since then, a wide range of crops, such as soybeans, wheat and rice have been approved for agricultural use, along with GM bacteria grown to produce large amounts of protein
  • Scientists in India have also developed strains of Sub-1 rice, which are much more resistant to flooding
  •  Flooding is a major issue in rice-growing regions of northern India and Bangladesh, set to become worse as the climate crises develops, and now 6 million farmers in the region are using Sub-1 rice to safeguard their crops against inundation
  • Golden rice, on the other hand, is a GM strain modified to contain vitamin A, designed to combat the shortage of dietary vitamin A in parts of Asia and Africa
2.1. Disease resistance
Gene editing technology has also helped save crop production from blights 
In the late 20th century, the papaya ringspot virus almost wiped-out papaya crops in Hawaii, but a local scientist developed a modified papaya that was resistant to the virus. Seeds were distributed to farmers, saving papaya production a decade later
Currently there’s no real solution except for massive fungicide applications
No one wants that, so we worked on adding genes or DNA changes from distantly related plants to achieve better resistances to the fungus
3. GM Controversy
  • Many people find the idea of GM foods hard to swallow — a 2020 opinion poll found 50% of people in 20 surveyed countries perceived GM foods as unsafe
  • When GM crops were first developed 30 years ago, uncertainty and concerns about safety were shared by scientists, but things are different now
  • Scientists say that "GM food is completely safe to eat, and 30 years of information showing it’s not dangerous for the environment"
  • There are concerns big corporate interests from companies like Monsanto, which promote more pesticides and monocultures and wrong forms of agriculture and seeds sold to farmers and expensive prices
4. GM Food Industry
  • GM agriculture is moving on from the Monsanto big-dog corporate model
  • GM products are increasingly focused on social and public enterprise and the industry is looking at more local solutions that help smallholder farmers in developing countries
  • Regulation and licensing are a huge part of this. Many, including Replanet, strongly advocate for open-source seeds and GM technologies
  • You can develop GMOs without patents developed by humanitarian public organizations
  • It’s about creating a licensing landscape that empowers local farmers to adapt to the demands of sustainable agriculture, but quickly enough to meet rising populations and climate change
