7 Questions on Ecological footprint EEn. 2.8.4 7 Questions on Ecological footprint Humanity needs what nature provides, but how do we know how much we’re using and how much we have to use? Eric Angat Teacher

Ecological footprints measure humanities demand on nature. How do we affect nature? Ecological footprints measure humanities demand on nature. Everything that we do has consequences… http://www.myfootprint.org/

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.

Lower ecological footprint means less strain to the environment, that means less pollution and destruction. http://www.footprintnetwork.org/en/index.php/GFN/page/footprint_basics_overview/http://www.footprintnetwork.org/en/index.php/GFN/page/footprint_basics_overview/

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 2050, we will need almost 2 more Earths to survive. # of Earth In 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

1. What are the six types of ecological footprint? 1. Carbon footprint 2.Grazing footprint 3. Cropland footprint http://cantorsbiologyblog.blogspot.com/2013_10_01_archive.html?p=ecological+footprint 4. Forest footprint 5. Fishing footprint 6. Built-up footprint

2.25 football fields =1 hectare 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 needs 3.20 football fields to sustain their needs and wants. 2.25 football fields =1 hectare 1 football field is 1.1 acres http://www.grafika24.com/countries-with-biggest-ecological-footprint/ 2.25 football field =1 hectares 1 football field is 1.1 acres http://wiki.answers.com/Q/How_many_hectares_are_there_in_a_football_field#slide=2&article=How_many_hectares_are_there_in_a_football_field

2. How can you lessen your ecological footprint?

2. How can you lessen your ecological footprint?

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 papers and other materials from the forest. By reusing, reducing and recycling.

3. Why do we need sustainability?

3. Why do we need sustainability? If we destroy our environment we will no longer have habitat and food sources in the future.

4. Why should we be afraid of global warming?

4. Why should we be afraid of global warming? Global warming leads to the melting of polar ice caps, climate change, flooding, drought, etc.

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). Toxic pollutants from household cleanser. sewer Eutrophication http://www.savrbay.com/cgl/whatis http://poopy.org/water-pollution/500000-gallon-sewage-spill-in-san-francisco-bay/

5. When a sewer pipe breaks near a stream which would most likely occur? increase in salinity decrease in dissolved nitrogen decrease in dissolved oxygen increase in pesticides

affect our environment? 6. How does our culture of consumption affect our environment?

6. How does our culture of consumption affect our environment? When we consume too much we also produce too much trash that poisons our water, land and air.  

7. Why is recycling so important in attaining sustainability?

Recycling lessens consumption which means less stress to our 7. 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.

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
