Question

III Read thefollowing passage and answer the questions below. 5 X 1 =5
Government aid is needed to help cities build all kinds of waste-treating facilities. Above all, man should strive to contain natural decay by ‘recycling’ or ‘re-using’ as much waste as possible. Magnetic extractors in incinerators could do an excellent service by using materials that disappear fast.
To cut air pollution, a Japanese process can be used to convert ash into cinder blocks. Recovering waste at the source is almost always cheaper than clearing later. Take sulphur for example, which is in short supply round the world. Wasted sulphur dioxide belched from smokestacks could be trapped in the stack and converted to sulphuric acid or even fertiliser.
We can be sure that just as technology has polluted the land, it can also depollute it. The real question is whether enough people want to take action. The trouble with modern man is that he tends to be bored by the news that pesticides are threatening remote penguins and pelicans. The false assumption that nature exists only to serve man is the root of an ecological crisis,a crisis that ranges from the lowly litter-bug to the madness of nuclear proliferation. At this hour man’s only choice is to live in harmony with nature, not conquer it.

1. What is meant by pollution?
2. What are the two effective ways by which natural decay can be controlled?
3. Name any two modern equipment to dispose solid waste.
4. Mention at least one method to contain air pollution.
5. What will bring immediate change in the environment?​
