Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular free time activity in Britain is going for a walk. And when joggers (慢跑者) jog, they don’t run the streets. Every one of them automatical
ly heads to the park or the river. It is my firm belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not.
But despite this, our children are growing up nature-deprived (丧失). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD (多动症). Those whose housing had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
A study in Sweden indicated that kindergarten children who could play in a natural environment had less illness and greater physical ability than children used only to a normal playground. A US study suggested that when a school gave children access to a natural environment, the entire school would do better in studies.
Another study found that children play differently in a natural environment. In playgrounds, children create a hierarchy (等级) based on physical abilities, with the tough ones taking the lead. But when a grassy area was planted with bushes, the children got much more into fantasy play, and the social hierarc
hy was now based on imagination and creativity.
Most bullying (恃强凌弱) is found in schools w
here there is a tarmac (柏油碎石) playground; the least bullying is in a natural area that the children are encouraged to explore. This reminds me unpleasantly of Sunnyhill School, with its hard tarmac, where I used to hang about in corners dreaming about wildlife.
But children are frequently discouraged from involvement with natural spaces, for health and safety reasons, for fear that they might get dirty or that they might cause damage. So, instead, the damage is done to the children themselves: not to their bodies but to their souls.
One of the great problems of modern childhood is ADHD, now increasingly and expensively treated with drugs. Yet one study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is much better when they have access to nature. The most important for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality.
In wider and more difficult areas of life, there is evidence to indicate that natural surroundings improve all kinds of things. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
Dr William Bird, researcher from the Royal Society for the Protection of Birds, states in his study, “A natural environment can reduce violent behaviour because its process helps reduce anger and behavior that people might regret later.” Wild places need encouraging for this reason
, no matter how small their contribution.
We tend to think human beings are doing nature some kind of favor when we are protecting nature. The error here is far too deep: not only do humans need nature for themselves, but the very idea that humanity and the natural world are separable things is damaging.
Human beings are a species of animals. For seven million years we lived on the planet as part of nature. So we miss the natural world and long for contact with non-human life. Anyone who has patted a dog, stroked a cat, sat under a tree with a glass of beer, given or received a bunch of flowers or chosen to walk through the park on a nice day, understands that.
We need the wild world.
It is necessary to our well-being, our health, our happiness. Without other living things around us we are less than human.

Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.

CONCORD， N.H.—Torrential rain forced hundreds of people from their homes in parts of New England on Sunday， as water flowed over dams and washed out roads.
The governors of New Hampshire and Massachusetts declared states of emergency. Maine’s governor also declared a state of emergency for one county. “It’s a very serious situation，” said New Hampshire Governor John Lynch， adding that forecasters were predicting 12 to 15 inches of rain by the end of the storm in parts of southern New Hampshire. “It continues to change and the situation continues to worsen.”
In some towns， police and fire crews used boats to get people out of their homes and stranded cars after hundreds of roads were damaged. Others got around in kayaks(皮船). Some towns shut down， not letting anyone pass except emergency vehicles. “The town is cut right in half，” said Glenn Laramie， police chief in Andover， N.H.
A dam in Milton， N.H.， was in danger of failing， which could send a 10-foot wall of water downstream， the National Weather Service said in a bulletin. People downstream were being evacuated from the town.
In Massachusetts， cars were pulled from flooded streets in downtown Peabody， about 20 miles north of Boston， and about 300 people were evacuated from an apartment complex for seniors. Businesses stacked sandbags at their doors， trying to prevent damage from water that at one point rose to waist-deep.
Some parts of New Hampshire had seen 7 inches of rain by midday Sunday and forecasters said up to 5 more inches might come during the day. About 100 residents were evacuated from their homes in Wakefield， N.H.， because of concerns about two dams in the area.
Flooding in New Hampshire in October killed seven people， carried off homes and washed away miles of roads down to bedrock.
In Maine， flooding was reported on 60 roads in the southern part of the state， said governor’s spokeswoman Crystal Canney. More than 50 homes in Sanford and several in Kennebunk also were evacuated， state officials said.

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.
