Investigan cultivos en el Reino Unido
UK crop research
Britain's academy of sciences, The Royal Society, is warning that the world will have to increase food production by 50% by 2050. It has recently published a report calling on the UK government to spend more than $3bn on crop research.

The Royal Society says that by the middle of the century the global population may reach 9 billion. And feeding those extra mouths is a major challenge for the planet, compounded by the spectre of global warming.
Professor David Baulcombe of Cambridge University, who led the research, says a billion people are already malnourished. Professor Baulcombe says the money the government should plough into crop science is needed immediately. If we wait ten years, he says, it may be too late. The genetic manipulation he refers to could produce crop strains resistant to disease, drought and salinity.
But the issue of genetically modified crops is still something of a hot potato, despite the technology being already used by millions of farmers. Environmental groups say the usefulness of GM crops has not been proven, and the threat they pose by letting altered genes spread into other plants is significant.
