A new study shows that rising levels of planet-warming gases may reduce important
nutrients in food crops.
Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers
grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are
predicting for our planet by the end of the century. They found that the resulting rice crops had
lower than normal levels of vitamins, minerals and protein. The researchers said the effects of
planet-warming gases would be most severe for the poorest citizens in some of the least
developed countries. These people generally eat the most rice and have the least complex diets,
they noted.
In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They
pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future.
Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels
of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5
percent less zinc（锌）an rice grown under normal r,vitamin E levels increased
by about 13 percent on average.
The results are bad news, “especially for the nutrition of the poorer population in
less-developed countries,” said the University of Tokyo’s Kazuhiko Kobayashi, who helped to
write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar,
Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.
One of the scientists is Sam Myers of Harvard University in the American state of
Massachusetts. He said that findings like this are an example of the surprises climate change
create. “My concern is there are many more surprises to come,” he said.
Myers noted that pollution, loss of some species, destruction of forests, and other human
activities are likely to produce unexpected problems. He said that you cannot completely change
all the natural systems that living organisms have grown to depend on over millions of years
without having effects come back to affect our own health.
The new study suggests a way to lower the nutritional harm of climate change. One way,
Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher
carbon dioxide levels.
