Our Concern
The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Only in the present century has one species of man acquired significant power to alter the nature of his world.
The rapidity of change follows the pace of man rather than the pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are creations of man’s inventive mind, having no counterparts in nature.
We have put poisonous and biological potent chemicals into hands of persons largely ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. We have allowed these chemicals to be used with little or no advance investigation of their effect. Future generations are unlikely to forgive our lack of concern.作者: jiaoyuzhu 时间: 2009-5-30 13:22

Gardening in the America
Believe or not, 43 million Americans are gardening, that is about one in six. Gardeners, of course count in many verities. Not surprisingly, most of them are people who live in the suburbs and enjoy planting flowers, or maybe a small vegetable garden. The average age of the gardeners in the America is about 45 years old. They are usually for somewhere in the middle class. But the fastest growing groups are city drillers. Urban resident are finding ways of gardening even in the crowd areas. Many go to large public gardens as please desiring by the city for garden, and you can actually range on you own plot. Still, other people use their bell balconies or rooftops where they can find space to plant small pages of green.作者: yoyo530521 时间: 2009-6-19 17:24
