The history of life on earth has been a history of interaction between living things and their surroundings.
The North Face Realization 3 in 1 Jacket Men’s,
to a large extent, the physical form and the habits of the earth’s
vegetation and its animal life has been molded by the environment.
Considering the whole span of earthly time, the opposite effect, in
which life actually modifies its surroundings, has been relatively
slight. Only in the present century has one species–man acquired
significant power to alter the nature of his world.
During the past quarter century this power has not only become increasingly great but it has changed in character.
The North Face Windproof 3 in 1 Jacket Men’s,
the most alarming of all man’s assaults upon the environment is the
contamination of air, earth, rivers, and sea with dangerous and even
lethal materials. This pollution is for the most part irrecoverable. In
this now universal contamination of the environment, chemicals are the
sinister partners of radiation in changing the very nature of the world,
the very nature of its
life.
It took hundreds of millions of years to produce the life that now
inhabits the earth. Given time not in years but in millennia life
adjusts, and a balance has been reached. But in the modern world there
is no time.
It is not my contention that chemical insecticides must never be used.
North Face Women’s Bionic Jacket, I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely
or wholly 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. I contend, furthermore, that
we have allowed these chemicals to be used with little or no advance
investigation of their effect on soil, water, wildlife, and man himself.
Future generations are unlikely to forgive our lack of concern for the
integrity of the natural world that supports all life.
