| The whole industrial process which
makes many of the goods and machines we need and use in our daily lives, is
bound to create a number of waste products which upset the environmental balance
or the ecological(生态的)balance as it is known. Many of these waste products can
be prevented or disposed(处理) of sensibly, but clearly while more and more new
goods are produced and made complex, there will be new, dangerous wastes to be
disposed of, for example, the waste products from nuclear power stations. Many
people therefore see pollution as only part of a larger and more complex
problem, that is, the whole process of industrial production and consumption of
goods. Others see the problem mainly in connection with agriculture, where new
