New discoveries and technological breakthroughs are made every year. Yet, as the information industry moves forward, many people in society are looking back to their roots in terms of the way they eat. A "locavore" movement has emerged in the United States. The movement supports eating foods grown locally and sustainably, rather than prepackaged foods shipped from other parts of the world.

Experts hold that eating local has many merits, and is expected to become a trend featuring sustainability. Erin Barnett is the director of Local Harvest, a company that aims to help connect people to farms in their area. By eating local, she argues, people have a better and more personal understanding of the impact their food consumption has on the rest of the world. "There is a way of connecting the point, where eating locally is an act that raises our awareness of sustainable living," Barnett says.

The United States' agricultural output is one of the highest in the world, says Timothy Beach, a professor of geography and geoscience at the University of Texas in Austin, Texas. "There's just no other place on Earth where the amount of input is so productive," Beach says of American agriculture. "Nobody can cut off the food we need."

However, the US food system is not sustainable because of its dependency on fossil (化石) fuels, says Beach. Equipment used on "extremely productive" farms is quickly consuming Earth's natural resources, particularly oil. Additionally, the production of agricultural supplements (补充剂)，such as fertilizer, uses large amounts of energy.

The world has used close to half of the global oil supply, Beach says, and the second half will be consumed at an even faster rate because of the growing population and economic development. Although many businesses are experimenting with wind, solar, and biofuel, Beach says there's nothing that we see on the horizon that can replace it. "There is no way on Earth we are using fossil fuels sustainably. Then we have to reconsider the impact of eating local," he says.

Adults check their phones, on average,360 times a day, and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our emails or social media feeds, and suddenly we've been sucked into endless scrolling.

It's an awful circle. The more useful our phones become, the more we use them. The more we use them, the more we lay neural（神经的） pathways in our brains that lead to pick up our phones for whatever task is at hand-and the more we feel an urge to check our phones even when we don't have to.

What we do know is that the simple distraction of checking a phone or seeing a notification（通知）can have negative consequences. This isn't very surprising; we know that, in general, multitasking does harm to memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It's true for everyday tasks that are less high-risk, too. Simply hearing a notification "ding" made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task.

It isn't just the use of a phone that has consequences-its me re presence can affect the way we think.

In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible（like on a desk）, nearby and out of sight（like in a bag or pocket）, or in another room. They were found to perform far better when their phones were in another room instead of nearby-whether visible, powered on or not.
