Eighty-eight per cent of scientists from the American Association for the Advancement of Science say genetically modified organisms (GMOs) are safe to eat. But a fear of GMOs, as well as strong opposition to them still exist. When it comes to human consumption, some scientists believe that more testing needs to be done, while environmental critics are concerned about the impact of GMOs on the ecosystem. Others worry that only major biotech industry players will benefit from GMOs - not small-scale farmers who need the most help. Still, proponents argue that the benefits of genetic engineering for society are huge. They say production and profit will be lifted, helping tackle poverty and feeding the world’s growing population, projected to reach 9.6 billion by 2050. We talk to activists and experts on both sides of the debate at 19:30 GMT.
