9 Questions on Ecological footprint Eric Angat Teacher Humanity needs what nature provides, but how do we know how much we’re using and how much we have to use? EEn
How do we affect nature? Ecological footprints measure humanities demand on nature. Everything that we do has consequences…
Ecological Footprint is the amount of land and water required to sustain our consumption patterns and absorb our wastes on an annual basis. 1. What is Ecological Footprint?
Sustainability utilizing natural resources without destroying the ecological balance of an area.
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 to create new products. Sustainable development is development that meets the needs of the present without compromising the ability of future
In 2007, our population has exceeded what our planet can provide. We need another ½ earth in order to survive normally. In 2050, we will need almost 2 more Earths to survive. Or survive, if we attain sustainability. Is it possible? # of Earth Years
2. What are the six types of ecological footprint? 1. Carbon footprint 3. Cropland footprint 2.Grazing footprint 4. Forest footprint 6. Built-up footprint 5. Fishing footprint
Greatest waste produced! Every American needs 7.19 global hectares (gha) to sustains their needs and wants. That means every American needs 3.20 football fields to sustain their needs and wants football fields =1 hectares 1 football field is 1.1 acres
3. What do each of the six types of ecological footprint represent? 4. How can you lessen your 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 CO 2 Representations of the different types of 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 papers and other materials from the forest. How to lessen our ecological footprint! By reusing, reducing and recycling.
5. Why do we need sustainability?
If we destroy our environment we will no longer have a habitat and food source. We need to think about our future food source.
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.
sewer Sewer water contains a lot of bacteria that uses a lot of oxygen. This makes lakes polluted and anoxic ( NO oxygen). Eutrophication
7. When a sewer pipe breaks near a stream which would most likely occur? A.increase in salinity B.decrease in dissolved nitrogen C.decrease in dissolved oxygen D.increase in pesticides
8. How does our culture of consumption affect our environment?
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.
9. Why is recycling so important to attain sustainability?
9. Why is recycling so important to attain sustainability? Recycling lessens consumption which means less stress to our environment. Recycling lessens waste and pollution in the environment. Recycling lessens the need for more sanitary landfills.
Reminders 1. Write the title of the project. The title of the project is Ecological footprint. 2. Write your names on your project and your class period.
