Living things
Plants and animals that live on land or water- rivers, lakes and sea= marine animals

What does it mean if we abuse R
When we use R in a way of damaging them
Info on WHALES
ABOUT: many species come to our waters to breed/migrate
USE: Blubber - fatty tissue that keeps whale warm >oil >soap >magerine >cooking fat >candles >cosmetics
Ambergris - waxy substance
>fix scent in perfume
Whale Meat - popular in Japan
KILL: large spears - harpoons
Guns
Carcasses taken to whaling stations in CT and Durban
Processed and exported
ABUSE:
1975 - so many whales killed
> not enough to support whaling industry
> resource = overused
1979 - SA banned whaling
> felt whaling was cruel and unnecessary
> products could be made from other things
> lost jobs
NOWADAYS: visit the Cape coast to watch whales at Hermanus - encouraged tourism
- jobs
Info on Air
Air we breathe is a mixture of gases
Oxygen - breathe
- fires to burn
Carbon Dioxide - plants > make food
Some gases harm people and environment
AIR POLLUTION: harms ppl and environment
>Petrol and diesel driven engines
>Burning coal and oil at home, factories and power stations
>Coal fires add soot and ash to the air
Info on Acid Rain
Sulfur Dioxide + Nitrogen Oxide + Rain = Acid Rain
> damages buildings
poisons rivers and soil, killing plants and animals
Info on Global Warming
By burning coal and oil = Carbon Dioxide = Earth’s temperature rising = GLOBAL WARMING
Causes climate patterns change
Polar ice is melting
=
Raising sea levels
=
Flooding land
AFFECTS
Natural Vegetation
Farming
Food Supply
Acid rain
Rain that has acid in it
Global warming
The increase in the temperature of the earth’s atmosphere
Climate change
Change in the weather conditions of a place
Info on Forests
Take Carbon Dioxide out of the air
Help lower global warming
SA’s forests
>wide variety of indigenous trees and other plants
>habitat of many animals that depend for food and shelter
As population grows = trees get cut down
RESULT - only few patches of natural forests left
Deforestation
