Scientists warn: shrinking vegetable diversity is a global crisis
An international team of experts, writing in the Proceedings of the National Academy of Sciences, warns that simply producing enough vegetables will not solve global nutrition problems. The key is restoring biodiversity: Poland once had at least 600 apple varieties, and South America had 4,000 potato varieties, but globalisation has narrowed diets to just a few dozen widely cultivated species. Losing traditional varieties strips communities of natural vitamin sources and crops best adapted to local conditions.
