Most developed nations such as Australia, Japan and Europe do not approve of GMOs. Most of these countries have bans on the production and sale of genetically modified foods because of the health concerns that have been found after the consumption of GMOs.
With GMOs, farmers are now able to produce plants that are more responsive to plant nutrients and that can be grown at almost any time of the year. Farmers are now able to sell their genetically engineered foods to developed countries, such as the US, that are willing to buy their foods. The US buys genetically engineered foods from farmers and sell it in grocery stores, without labels. For farmers, that means more sales.
