      Five million people visit Grand Canyon in the US every year. For the purpose of helping protect Grand

Canyon for your fellow visitors and future generations, please follow the guidelines below.

Camping 

To protect the park, camping is allowed only within permitted campgrounds. Permits (许可证) are required

for overnight camping at the North Rim. Advance booking can be received by mail. Please write: Information

Center, P.O. Box 129, Grand Canyon, AZ 86023

Fires

Because of the fire danger, campfires are not allowed except at Mather and Desert View campgrounds.

Collection of firewood is not allowed either.

Hiking

Please stay on permitted paths. Otherwise you may destroy desert plants. Pack out what you pack in, so you

leave no signs of your visit. It is important to keep in mind that you are in a national park where wildlife exists.

Weather

The weather at Grand Canyon can change very quickly. With so much rock, lightning causes a particular

danger during sudden summer storms. These storms also frequently bring floods inside valleys, a danger to

hikers. Watch the skies and check daily weather reports.

Wildlife

Do not feed park wildlife. There have been a few cases at Grand Canyon National Park where deer were

purposely shot because they ate plastic bags that left them sick and weak. Hungry deer can be dangerous and

they have kicked and bitten visitors at Grand Canyon. Some other animals will also beg and bite. For your own

safety and the well-being of the animals, please do not feed wildlife, no matter how gentle they may appear.

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”

A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.

Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.

Farmers aren't the only ones who benefit. Consumers(消费者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.

D．the output of corn in the same field is increased.
