Overall, i think GM food is beneficial but consumers should have the right to know whether they are buying/consuming GM food just like organic products. Hence, i think the government should make it compulsory for food companies to label GM food. In the mean time, there may be no serious complication such as serious illness due to GM food consumption but it will be to late to wait till an outbreak really did happen. Hopefully, more research will be done asap and GM food will be proven safe in terms of health issue.
As for environmental issue, i think it is not as serious as there may be solutions to solve the problem. According to a source: Another possible solution is to create buffer zones around fields of GM crops. For example, non-GM corn would be planted to surround a field of B.t. GM corn, and the non-GM corn would not be harvested. Beneficial or harmless insects would have a refuge in the non-GM corn, and insect pests could be allowed to destroy the non-GM corn and would not develop resistance to B.t. pesticides. Gene transfer to weeds and other crops would not occur because the wind-blown pollen would not travel beyond the buffer zone. http://www.csa.com/discoveryguides/gmfood/overview.php
