Over the preceding half - century , a few staple foods like rice and soybeans have come to command hoi polloi ’s diet all over the Earth . And this could spell out disaster .
A new inquiry paper published inProceedings of the National Academy of Sciencesexplores how local staple crops like cereal and roots have been supersede by “ energy - dense foods ” like laurel wreath crude . “ Wheat is a major staple in 97.4 percentage of nation and Sir Tim Rice in 90.8 percent ; soybean has become significant to 74.3 percent of countries , ” the research worker say in a release about the survey . Not only does this mean our diet are less diverse , and less level-headed , but it could mean famine are on the horizons .
The problem is that when the creation depends on a few staple crops for nourishment , the wellness of those crops are synonymous with world food security system . And if there is a drouth , or pests , we ’re more vulnerable to famines if we ’re only arise one or two kinds of staple crops . It would essentially be like the Irish potato famine writ large . One plant life disease could take out the world ’s soybean provision , just the way a tater disease rob Ireland of its export crops and food supply in the mid - nineteenth one C .
Luigi Guarino , a study co - author and aged scientist at the Global Crop Diversity Trust , said in a release :
Another danger of a more homogenous planetary food for thought basket is that it wee factory farm more vulnerable to major threat like drought , insect pest and diseases , which are likely to become high-risk in many parts of the humans as a result of clime change . As the global universe rise up and the pressure increase on our global food system , so does our dependence on the global harvest and production system that give us . The price of failure of any of these crops will become very high .
