1. GLOBAL WARMING AND SUSTAINABILITY “ Because we don’t think about future generations, they will never forget us” Henrik Tikkanen Marta Aparício

3. Global Warming “ For the past 150 years, Earth’s global temperature has been rising.” GLOBAL WARMING AND SUSTAINABILITY Marta Aparício

4. EVIDENCES OF GLOBAL WARMING GLOBAL WARMING AND SUSTAINABILITY Marta Aparício CO 2 levels Global Temperature years ago

5. The Greenhouse Effect Global Warming GLOBAL WARMING AND SUSTAINABILITY “ For the past 150 years, Earth’s global temperature has been rising.” The Sun’s energy enters the atmosphere in the form of light waves Most of the energy is sent back into space The Earth is heaten up by the Sun and radiates the infrared waves back into space The greenhouse gases traps a lot of the infrared radiation Marta Aparício

6. GLOBAL WARMING AND SUSTAINABILITY Marta Aparício Greenhouse gases Methane - 18% Nitrous Oxide - 6% Other Gases - 13% CFC - 14% Carbon Dioxide - 49%

7. Why do the levels of CO 2 diminish once a year? GLOBAL WARMING AND SUSTAINABILITY Marta Aparício CO 2 levels CO 2 levels The leaves fall and disgorge CO 2 The leaves come out and breath in CO 2

12. “ According to the main relation between Mankind and Envyronment, we need to guarantee to a minimum wellfare of the society, as to a maximum utilization of the resources our planet has.” SUSTAINABILITY “ Sustainable development applies to present needs without compromising the needs of future generations” GLOBAL WARMING AND SUSTAINABILITY Marta Aparício

18. THE THREE “R’s” CYCLE FOR THE CONSUMER R educe, R euse and R ecycle GLOBAL WARMING AND SUSTAINABILITY Recycling takes far less energy than does sending recyclables to landfills and creating new paper. Marta Aparício Product Reduce No Don’t buy Do you really need to buy it? Yes Buy Is it possible to recycle? Is it possible to reuse it? Waste Reuse Recycle Is it a big material? (like forniture or home machines) Use it racionally No Yes No Yes No Yes Choose recycled, biodegradable or reloadable products Put it in the garbage Contact your autarchy Collect your waste and put it in the right collector Deteriorated product that is useless (not including agricultural pesticides)

19. Sources of energy GLOBAL WARMING AND SUSTAINABILITY Coal Oil Natural gas Biomass Wind Waves Solar Geothermal Electricity Heat Transportation Industry Our home Services Geothermal power station Petrol/Fuel Oil refinery Hydro Marta Aparício

20. GLOBAL WARMING AND SUSTAINABILITY Marta Aparício Renewable sources of energy are being produced (naturaly or by human intervention) at a very fast speed so that our waste won’t lead to its extintion. Ex: Wind power, solar power, biomass Nonrenewable sources of energy are wasted more rapidly than they are produced naturaly. Ex: Coal, oil, natural gas (fossil-fuels)
