Nowadays we all understand that unbridled industrialization, which has been going on for years, has brought about irreversible changes into the world climate and is threatening the life on the planet. The principle “Hold your breath until your death” is frightening.
The biggest fear is global warming and the depletion of the ozone layer. There’s a report that an area of the Amazon rainforest is felled every second of every day, seven days a week. It means that the ecological balance is being upset. The result is that we have strange sudden hurricane force winds that we have never had before, holes in the ozone layer, skin cancer. All people and businessmen have to admit that it’s high time to begin to rectify the mistakes that were made in the past. Of course we should start with ourselves. People should collect the things which are reusable, think about the safe disposal of spray canisters and other wastes. Businesses should run courses on ecological awareness and raise environmental consciousness of their management and employees. We all can put pressure on federal and local governments to make the policies of businesses environmentally friendly.
Agree or disagree with these statements.
Waste has been with us since man began to live in large communities. London in 1684, with its open sewers, horse traffic, and out-the-window garbage disposal, was not more healthful than areas around industrial waste disposal sites in 2002. But the nature of waste has changed as well as people’s knowledge, which has increased dramatically over the past decade. Enhanced sensitivity to the siting of disposal facilities resulted in the reevaluation of waste management approaches. The options are: reuse, reprocess and recycle.
In order to maximize the quantity of reused or recycled waste, waste generators must develop viable processes or find someone willing to use their waste.
It is important to recognize that without the existence of a real economic advantage to do so wastes will not be recycled. To maximize the economic advantage of recycling, businesses first seek a process that can use the waste as it is generated. Next they seek nearby specific users who are willing to substitute garbage for the nice clean raw material. Obviously, the first place to look is within the plant producing the wastes — both try to minimize the amount produced, and to determine whether other operations within the plant could use the waste.
Say which of the statements below are true and which are false.
