Genetically modified crops have three main characteristics. First of all, they have an extinction effect on the original wild crops. Once genetically modified crops are planted, wild crops will become extinct. This has been proved by practice and is no longer a theoretical problem. Second, genetically modified products are sterilized products, just like mules. Unlike the original crops, you can use the grain you have laid as seeds for the coming year, but you can only buy new seeds every year. Almost all the patents of genetically modified seeds of major crops in the world belong to Monsanto, Bayer and DuPont, and they have to pay expensive patent fees when purchasing them. Third, there are special requirements for pesticides and fertilizers, and only pesticides and fertilizers designated by genetically modified seed companies can be used. The seeds of farmers in China can no longer be mastered by farmers themselves, because plants such as genetically modified rice cannot be kept. The autonomy of farmers in China and the basic rights of China people are in the hands of the interest groups and multinational companies behind them.
Other supporting costs of genetically modified foods, such as special herbicides and fertilizers, are in the hands of multinational companies.
Transgenic species pollute the original ecological species and the environment, so it is impossible to restore the original ecological species.
