Can I Make a Difference?
What is the controversy all about?
Tackling some of the myths
Using energy is bad. Year 10 student 2012
When are we going to see the effects of it so people can see there is a problem?
Year 10 student 2011
Carbon dioxide is bad Professor of Mining Geology, Uni of Adelaide Ian
Plimer, scientist and Climate change sceptic
“Carbon dioxide cannot be measured”. Tony Abbott,
Our Current Global Concerns? Hotter temperatures
Water Shortage & Droughts
Cyclones & Floods
Forests being cut down
Rising Sea levels
Our Current Global Concerns?
Climate ChangeThe controversy
A long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature
All animals breathe out carbon dioxide (small amount)
Plants remove carbon dioxide during the day and release oxygen
The problem is we are removing too may forests on Earth?
Current rate of deforestation is about 10 times the rate of reforestation
Plants take up Carbon Dioxide by Photosynthesis
Planting more trees would slow down the increase in carbon dioxide
The problem is we produce too much Carbon Dioxide because of fossil fuels (coal, crude oil and gas)?
Electricity (we use mainly brown coal in Australia)
Burn Fossil Fuels
Coal & GasProducesElectricity
Makes Carbon Dioxide
Transport (crude oil)
Energy for cars, trucks,
planes to move
Industry Production of materials

Global Carbon Project 2010; Data: Gregg Marland, Thomas Boden-CDIAC 2010; Population World Bank 2010
Australia Is 17th in producing carbon dioxide
emissions But per person we are third
Can I Make a Difference to My World?
Governments need to reduce emission of fossil fuels
More efficient use of our fuels
Governments need to make the move to renewable energy sources.
Renewable energy sources (solar, wind, hydro, wave, geothermal energy)
Securing a clean energy future
A carbon price alone is not enough!
This is more about a future energy strategy
We can make try and leave more sustainable lives?
Sustainability is the capacity to endure. For humans, sustainability is the long-term maintenance of responsibility, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use.
Use the car less, walk, ride a bike, carpool, public transport
Avoid products with lots of packaging
Move the thermostat down 2 degrees in winter
Move the thermostat up 2 degrees in summer
Use less hot water
Turn off electrical devices at the power point when you are not using them
Replace regular light bulbs with compact fluorescent ones
Plant a tree
We can solve problems
We reduced the Ozone Layer problem why not try and reduce the Enhanced Greenhouse Effect?
Ozone Layer The Ozone Layer is a layer of
molecules about 30 km above the Earth’s surface which protect us from the sun’s ultra violet rays.
Ultraviolet rays can burn us easily. (sunburn)
What causes the Ozone Layer to break down?
Certain chemicals (CFC’s) used in industry, in refrigerators and aerosols were reacting with the Ozone Layer and causing a hole to form in the protective layer over Antarctica.
What would happen to all the plants, animals and humans on earth if the hole in the Ozone Layer got bigger?
We would all be exposed to very high levels of ultraviolet light.
We would burn more easily.
Reduction in plant growth on the land and in the sea.
Similarities Both the Greenhouse & Ozone Layer
are environmental problems we have caused & are related to the sun.
Enhanced Greenhouse Effect is linked to the Earth’s infrared (heat) rays, while the Ozone Layer damage is related to the sun’s ultraviolet (burning) rays.
Differences The Enhanced Greenhouse Effect is
The hole in the Ozone Layer is slowly being reduced due to International collaboration. People have found alternatives to the chemicals that we used to use.
The Future The hole in the Ozone Layer is being
reduced. We have found a solution to this problem.
The Greenhouse Effect is the major environmental concern of this century. We need to find a solution to this problem.
