The effect of the genetically engineered organism on the environment is unknown. The effect of eating genetically engineered foods is unknown. There is no basis for meaningful risk assessment. There is no recovery plan in case of disaster. Scientists do not yet understand living systems completely enough to perform DNA surgery without creating mutations which could be harmful to the environment and our health.
Genetic engineers intend to profit by patenting genetically engineered seeds.
This means that, when a farmer plants genetically engineered seeds, all the seeds have identical genetic structure. Pollen from transgenic plants can cross-pollinate with genetically natural crops and wild relatives. Genetic engineering will help developing countries. To protect their investment, the farmers that use the seed sign a contract which prohibits saving, reselling, or exchanging seed. The family farms of the poorer nations depend on saved seed for survival.
