Let us take companies like Cargill and Monsanto as examples. It always goes back to what happened in India. Monsanto was making cotton-based products, but the cotton was infested with pests and half the cotton fields were devastated. When people found that out, they began to be afraid of GMOs. But the seeds must have been approved.
Who approves these products? Is it the company, like Monsanto or Cargill? Is it done in strict secrecy? Perhaps they do not want to reveal their secrets. Is approval done by Health Canada scientists? Who grants the certification, the approval for a product before it can be sold?
