QUESTION 8: CASE STUDY
Read the case study below, carefully, and answer the questions.
RECYCLING OF METALS
South Africa is suffocating under the tons of waste generated by
households and enterprises each year.
South Africa’s yearly waste could make a mound of rubbish that would
fill a rugby stadium and stretch 3,25 km into the air. It would weigh 560
million tons. Old food, cans, bottles, plastic, paper and organic materials
are thrown away by people daily and there are at least 37 000 ragmen
that try to make a living out of waste.
Recycling would be a very good solution for South Africa’s rubbish
problem, but few people can be bothered with recycling.
9
At least 80% of everything that lands up in the country’s refuse sites can
be recycled. We can begin by making our own compost for organic
waste. Paper, plastic and glass can be separated from other waste for
recycling.
QUESTIONS:
1. How many tons of waste is generated annually by
South Africans?
2. What does waste mostly consist of? Name any two.
(1)
(2)
3. How can South Africans relieve this problem?
(1)
4. Name one area where this problem holds serious implications for
us and explain in your own words.
(1)
5. Name one other problem that South Africa is experiencing
currently, and explain how this problem affects all of us, on a daily
basis.
Clue: It occurs in stages 1, 2 and 3.
