Research and Focussing Exercise
(2a) Super dams
(b) What happens when we damn the flow of a great river and form an immense body of water where there was none before?
(c) Negative effects on building damns
(d) Negative impact on the ecosystem, people who have to move, economy and health
(3) Negative effects on the ecosystem
-when a big dam is built, it may flood several thousand square miles of land -all living things will be drowned (ex. Plants, insects, etc.) -everything changes (ex. the chemistry of the water, habitat of fish, etc.)
Negative effects on the Baoules because of moving to another settlement due to building dams
-Bauoles lived in homes with no kitchens
-the only well was in adequate and too far away
-there would be no food until the new crops grew
-invited to learn how to fish but did not enjoy it and were afraid of water
-had to raise cattle on poorer soil
-forced to part with their homes
-mortality rates increased a significant amount after having to move
Negative effects on the economy
-costs a lot of money to resettle people because building new homes for them are expensive
-as practice spreads, starts to get more and more expensive
-when thousands of dollars are spent ahead of time on refugees, only a few can be resettled on the kind of good bottomland they lost.
Negative effects on health
-brings an explosion of water-borne diseases
-epidemics of river blindness, sleeping sickness, bilharzia, malaria, and yellow fever infecting 4/5 inhabitants
-when population grows, diseases will become a very serious threat
(4) There are many countries in the world that do not have as many opportunities, or is well developed as Canada. This may be because the nations do not have the resources to help them prosper or because of their government or many other reasons. Numerous less developed countries have been convinced that building superdams will help build their economy and provide what is needed. However they are suffering
