A Grassroots Remedy 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 leisure 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 instinctively heads to the park or the river. It is my profound 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 on Streatham Common, South London. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and odd new perceptions about what is best for children, that is to say, things that can be bought, rather than things that can be found

A major cause of the disease is not (21) known; there is no (22) evidence that screening is much help; and treatment (23) in about 90 percent of all cases, at present, therefore, the main strategy must be (24) . This may not always be true, of course, as for some other types of cancer, research (25) the past few decades, has suggested some importance in prevention, screening or treatment. (26) , however, we consider not what research may one day offer but what today’s knowledge could already deliver that is not being delivered, then the most practicable and cost-effective opportunities for (27) premature death from cancer, especially lung cancer, probably involve neither screening nor improved treatment, (28) prevention.
