The price of wheat, rice, corn and other staple grains has been on a downward spiral in recent years, with the world now consuming less than half of what it did in 2000, according to a new study.
In 2016, the United Nations Food and Agriculture Organization estimated that world grain supplies would need to be increased by about 4.3 billion bushels (18.5 million pounds) to meet the world food needs of 2020.
That’s about 4 percent of the global population’s current consumption.
The UNFPA said that the world is now consuming about 7 percent of its current needs for staple grains.
While that may sound like a lot, that’s still a lot of grains, and it’s a huge reduction in consumption.
It also means that global grain consumption has fallen about 40 percent from the 1980s, when grain consumption was about 80 percent of global production.
The report also found that the number of people on the planet living on less than $1.25 per day is about 20 percent of what existed in 1980.
“We need to start to change the way we eat,” said John Vester, who led the study, which was published in the journal PLOS ONE.
“What we need to do is reduce the amount of food we consume, and we need some help in that process.”
The report also analyzed food production in several countries around the world, including the United States, which accounts for nearly 90 percent of world grain production.
That country is currently experiencing a food shortage due to the Ebola virus outbreak.
“It’s important to know how the world eats,” Vester said.
“I think we need more research on how to feed more people.”
Vester and his team also looked at the impact of climate change on crop production.
They said that in many parts of the world crops are not growing as fast as they used to, due to extreme weather conditions.
It’s a problem because of the climate, but also because of land use changes, which may be changing land-use patterns.
The team also said that as food prices increase, it’s likely that people will start to consume less of what they produce.
