R2 What Effects The Size Of Eco Footprintsfor Blog

  1. 1. By the year 2050 the earth’s ecological footprint will become so large that we will need two earths to support the human population
  2. 2. Ranking cities by their eco-footprints… <ul><li>This is a WWF report showing the eco-footprint of their average resident </li></ul><ul><li>Salisbury and Winchester, highlighted in green are cities only 80km apart and have similar populations of about 43,000 people </li></ul><ul><li>So why do they have completely different eco-footprints? </li></ul>
  3. 3. Salisbury and Winchester <ul><li>You are going to use the information given to you to compare the eco footprints of these two cities. </li></ul><ul><li>You are then going to write recommendations to the City Council of Winchester to advise them how to reduce their city’s footprint. </li></ul>
  4. 4. What is GHA? <ul><li>The biocapacity is the size (capacity of) the earth that is productive (can be used) e.g. for farming, building etc. </li></ul><ul><li>A global hectare is a measurement of the average biocapacity. Add up the area of the world’s biocapacity and then divide it by the number of hectares on the earth’s surface. </li></ul>
  5. 6. What did winchester city council say? <ul><li>Response to WWF's Ecological Footprint Report </li></ul><ul><li>The WWF report ranks cities by their Ecological Footprint - this is the measure of land that can be attributed to resource consumption. </li></ul><ul><li>It measures the hectares it takes to grow our food and farm the animals we eat; the area that our house stands on and that oil refineries and other energy infrastructure we depend on take up; the hectares of forest that would be needed to absorb the CO2 emitted by our fuels; a share of the area taken up by our roads; and everything else we do that has an impact on the planet's ecology. </li></ul><ul><li>In response, Leader of Winchester City Council George Beckett said: &quot;The WWF report is really a critique of lifestyles in the South East region - or arguably much of the western world - and we are of course concerned that Winchester is having a negative impact on the environment. </li></ul><ul><li>The commitment to change by residents, organisations and businesses is crucial in making a difference - this is not something the Council can do alone. </li></ul><ul><li>We are taking action by creating a climate change plan for the district, improving recycling rates (now 44%), providing park and ride and eco-friendly buses, and improving energy efficiency of council houses but we acknowledge there is always more to be done. </li></ul><ul><li>http://www.winchester.gov.uk/NewsArticle.asp?id=SX9452-A7839C43 </li></ul>
  6. 7. What about Cambridge? <ul><li>In what ways does Cambridge put pressure on the environment? </li></ul>
  7. 8. What can we do to reduce our footprints? <ul><li>What can individuals do to reduce our eco-footprints? </li></ul>
