Water facts

  • More than 1 billion people did not have access to safe water in the year 2000.
  • In Mozambique approximately 16% of the inhabitants of the country have safe, clean drinking water.
  • In South Africa an average of 638 ℓ water is used per person per day. Only 2,5% of the total water supply of the world is fresh.

What is safe water? Find out!

  • Is your drinking water safe?
  • How can water be made safe?
  • Is water from a river always safe?
  • Do all the people in your area have access to safe water?
  • What can be done to ensure that everyone has access to safe drinking water?

6. Overpopulation

The population grows much faster in developing countries than in developed countries.

The population in Africa south of the Sahara is growing much too fast! According to one calculation there will be a tenfold growth in the population of Africa in the century between 1950 and 2050!

It is very important to keep in mind that on a continent such as Africa a tenfold growth in population will mean that there could possibly be a tenfold increase in the problems of the continent as well!

Remember that it is not the population alone that will increase – at the same time there is a great increase in the need for food, educational opportunities, housing, energy and job opportunities. Various social, political, economic and ecological problems also increase at the same rate.

7. Poverty

Poverty means being hungry. Poverty means having no shelter. Poverty means being ill and having no doctor or proper medical care. Poverty means having no access to a school, and not being able to read. Poverty means being unemployed; living in fear of the future – one day at a time.

In most of the developing countries there is an enormous disparity (gap) between the rich and the poor.

Activity 3:

To deal with the problem of poverty in my environment

[lo 3.1, 3.3]

Is poverty obvious in your area? How does one notice it? Have group discussions on possible ways in which to tackle the problem of poverty in your immediate environment. Try to generate suggestions that will provide relief in the long term; recommend plans that will bring about meaningful change and do more than merely feed the children for one day.

B. How can developed countries help the developing countries?

  • Health” is described by the World Health Organisation as the level of physical, spiritual and social well-being enjoyed by people. In the poor South the standard of food and sanitation is very low, and there is very limited access to fresh water. The general health of the inhabitants is much poorer than that of people in the developed countries. People who do not have enough good food and fresh water are much more susceptible to disease. The state has to give a great deal of support in preventing and treating disease. When someone is ill, he or she is unable to work, and this is very detrimental to the economy of the country.
  • The wealthy northern countries have already created various organisations that are involved in giving aid to the poor countries. Food and medical supplies are granted on a continual basis. However, because of the inadequate infrastructure of the poor countries, the distribution of such supplies often causes even more crises. Very frequently huge amounts of food and medical supplies never reach the people for whom they are intended. In the USA, Canada and Europe the farmers produce much more food than what is needed by the people of these countries. The surplus food can be bought and distributed in countries that have a chronic lack of food, or where natural disasters have occurred and there is great suffering and misery. Unfortunately, production costs have increased so greatly that it has become extremely expensive to buy wheat, maize and rice for distribution to people in distress.
  • A very important part of the income of many of the developing countries is derived from exporting their natural resources and primary products. Unfortunately the developed countries buy these products and resources at extremely low prices, and resell the processed products to the developing countries at very high prices. In this way the gap between the rich and the poor continues to grow all the time.
  • It is essential that the trade in the opposite direction be stimulated. Developed countries simply have to make their markets more accessible to the developing countries. Poor countries should be encouraged to manufacture their own goods and to export these products to the rich countries.


Learning Outcomes(LOs)

GEOGRAPHICAL ENQUIRY The learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.
Assessment standards(ASe)
We know this when the learner:
  • identifies sources of information, including simple statistics, to help answer the question about a social or environmental issue or problem;
  • selects and records relevant information from sources for specific purposes (including recording and observing in the field);
1.4 uses information to propose solutions to problems;1.5 reports on enquiries, through discussion, debate, structured writing, graphs, tables, maps and diagrams.
LO 2
GEOGRAPHICAL KNOWLEDGE AND UNDERSTANDING The learner will be able to demonstrate an environmental knowledge and understanding.
We know this when the learner:
2.2 identifies how access to different kinds of resources influences development in different places;
LO 3
EXPLORING ISSUESThe learner will be able to make informed decisions about social and environmental issues and problems.
We know this when the learner:
  • identifies inequalities within and between societies;
  • analyses some of the factors that lead toward social and environmental inequality at different geographical scales and in different places;
  • evaluates actions that lead to the sharing of resources and reducing poverty in a particular context.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
