Wheat is a main source of food for people across the planet, accounting for a fifth of the calories consumed globally. But as a result of climate change, scientists believe most parts of the world where the crop is grown will be hit by water shortages by the end of the century. And the US could be among the countries worst affected, the authors of the research published in the journal Science Advances told Newsweek.
If climate change isn't dealt with, by the year 2100, 60 percent of areas that grow wheat will be hit by water scarcity—up from the current level of 15 percent, according to the international team of scientists.
Co-authors Miroslav Trnka and Song Feng told Newsweek that in their previous research, they had shown climate change may cause soil to become less moist (湿润的) across most mainland US states, including those where wheat is grown. As a result, the US could be "one of the top most affected wheat producers" in terms of the increase in areas affected by severe droughts, they said in a joint statement.
Worryingly, existing research has predicted a 4. 0 to 6. 5 percent drop in global wheat production per 1 degree Celsius of warming if climate change isn't eased. And it's unlikely that wheat can be replaced if water becomes scarce, as it's not as thirsty as other crops and can do without water for a relatively long period of time.
"If multiple regions are affected by drought at the same time, it might be difficult to meet the demand even if the trade routes stay open and are not restricted by governmental measures," warned Feng and Trnka. However, he said, "Studies show that if we continuously improve the sustainability and technologies in the coming decades and allow for international trade, we may overcome the negative impacts of climate change."
Many people feel their parents are overprotective. When you want to go to a party, for example, they will try to stop you. It seems as if you are still a kid.
Find out which parent is more easy-going. You can bring him or her over to your point of view first. If you know your mom is more relaxed about it, persuade her first.

A couple in Ohio accidentally dropped off a bag containing almost $100,000 at an Ohio charity shop. Thanks to1employees, they got the money back.
The employees were going through 2 last week when they came across a 3. Inside was $97,004. "It was so much cash, "employee Kelsey Croy said. "I looked in the bag and we 4 it right there on the desk. And it was $97,004. "Thankfully, the owners 5 a receipt for tax purposes when they dropped off 6 that morning. The employees 7 called the couple but there was no 8.
Not wanting to 9 that amount of cash in the store, they called in the Zanesville Police Department. 10 repeated calls, officers finally got a hold of the couple. The couple hadn't realized the money was 11. They told police they withdrew all their money to another bank. On the way, they 12 at the charity shop to donate a bag of clothes. That's 13 the money ended up there. "When we finally 14 them, they just asked if they could get it sometime tomorrow, "the officer said.
The couple has since made contact with the original 15 who found the money to thank them. "I'm just glad that I meet with a bunch of honest and loyal people, "Croy said.
There are several reasons why school uniforms are a good idea. First of all, uniforms help the school look smart. The students feel that they belong to a particular group. When every pupil in the school wears the uniform, nobody (have) to worry about fashion. Everybody wears same style of clothes. Uniforms can be useful in unexpected ways. A school in Ireland has introduced an interesting new uniform. On the edge of the jacket, there is a piece of cloth gives off light in the dark. When the children are walking or (cycle) to school on dark mornings, car drivers can (easy) see them.
But can uniforms help improve school standards? The answer this question is not clear. One study in America found that students' grades (improve) a little after the school introduced uniforms. But some students didn't want (wear) the uniform. Other American studies showed no (connect) between uniforms and school performance.
School uniforms are (tradition) in Britain, but some schools are starting to get rid of them. Some very good schools don't have a uniform policy. However, uniforms are still popular. Pupils at about 90 percent of British secondary schools wear uniforms.
