4 1. What is Ecological Footprint? Ecological Footprint is the amount of land and water required to sustain our consumption patterns and absorb our wastes on an annual basis.
5 Sustainabilityutilizing natural resources without destroying the ecological balance of an area.
6 How can you lessen your Ecological Footprint and achieve a sustainable development? Reuse means use materials repeatedly.Move away from disposables!Recycle means using used materials tocreate new products.Sustainable development is developmentthat meets the needs of the presentwithout compromising the ability of future
7 In 2050, we will need almost 2 more Earths to survive. # of EarthIn 2050, we will need almost 2 more Earths to survive.We need another ½ earth in order to survive normally.In 2007, our population has exceeded what our planet can provide.Or survive, if we attain sustainability. Is it possible?Years

9 2.25 football fields =1 hectares 1 football field is 1.1 acres Every American needs 7.19 global hectares (gha) to sustains their needs and wants.Greatest waste produced!That means every American needs3.20 football fields to sustain their needs and wants.2.25 football fields =1 hectares1 football field is 1.1 acres2.25 football field =1 hectares1 football field is 1.1 acres
10 3. What do each of the six types of ecological footprint represent? 4. How can you lessen your ecological footprint?
12 Representations of the different types of Ecological Footprint 1. Cropland footprint – farms, tobacco, wheat 2. Grazing footprint – livestock like cattle 3. Forest footprint- wood for building, paper 4. Fishing footprint- fish for food 5. Built-on land footprint- houses, buildings 6. Carbon footprint- use of fossil fuel, trees needed to absorb CO2
13 By reusing, reducing and recycling. How to lessen our ecological footprint!Carbon footprint – lessen use of fossil fuel,plant trees. Recycle!Cropland footprint- do not waste food.Grazing footprint- do not waste food.Fishing footprint- do not waste food.Built on land footprint- population control,recycle, reduce, reuse.Forest footprint- do not waste papersand other materials from the forest.By reusing, reducing and recycling.
15 If we destroy our environment we will no longer have a 5. Why do we need sustainability?If we destroy our environmentwe will no longer have ahabitat and food source.We need to think about ourfuture food source.
17 6. Why should we be afraid of global warming? Global warming leads to the melting of polar ice caps and the alteration of weather patterns or climate change.
18 Sewer water contains a lot of bacteria that uses a lot of oxygen Sewer water contains a lot of bacteria that uses a lot of oxygen. This makes lakes polluted and anoxic ( NO oxygen).sewerEutrophication
19 7. When a sewer pipe breaks near a stream which would most likely occur? increase in salinitydecrease in dissolved nitrogendecrease in dissolved oxygenincrease in pesticides
20 affect our environment? 8. How does our culture of consumptionaffect our environment?
21 8. How does our culture of consumption affect our environment?Because when we consume too much we also produce too much trash that poisons our water, land and air.
22 9. Why is recycling so important to attain sustainability?
23 Recycling lessens consumption which means less stress to our 9. Why is recycling so important to attainsustainability?Recycling lessens consumptionwhich means less stress to ourenvironment.Recycling lessens waste andpollution in the environment.Recycling lessens the need formore sanitary landfills.
