  2. 1st Law: Everything is connected to everything else Humans and other species are connected (dependent) on a number of other species.

  4. 1st Law: Everything is connected to everything else Making connections: What is the connection between the rise of McDonalds outlets in China and the massive deforestation in the Amazon forest in Brazil. Farming the Amazon http://environment.nationalgeographic.com/environment/habitats/last-of-amazon/#page=4

  5. World’s second largest • producer of beef • 3rd largest exporter • 2nd largest producer and • exporter of soy bean

  6. 2nd Law: Everything must go somewhere No matter what you do, and no matter what you use, it has to go somewhere. For example, when you burn wood, it doesn't disappear, it turns into smoke which rises into the air, and ash, which falls back down to the earth.

  9. 3rd Law: Nature knows best Like it says, nature knows best. Mothers milk vs. milk formula http://www.youtube.com/watch?v=1pW93kKZYMM

  10. Nature knows best: How the natural world is inspiring new innovations • When we look at the world around us, we see what has survived the test of time. In other words, nature doesn't just show us results - it shows us the most optimal ideas available. • As a result, scientists are creating more products that are inspired by nature. The BlackBerry phone was inspired by a butterfly's wing.

  11. Nature-inspired designs Solar Leaf Bio-inspiration, also known as biomimicry, is a discipline that studies and learns from nature's best ideas to generate breakthrough products and technologies.

  12. Nature knows best: How the natural world is inspiring new innovations • Go to the Following Website for Examples: http://www.biotrue.com/world.html http://brainz.org/15-coolest-cases-biomimicry/ A new car design inspired by a boxfish A Speedo swimsuit line inspired by shark's skin

  13. 3rd Law: Nature knows best Artificial Foods anyone? http://www.theonion.com/video/taco-bells-new-green-menu-takes-no-ingredients-fro,14348/ The Store Wars - Organic food vs. chemicals and GMOs http://www.youtube.com/watch?v=MfTQergr29M

  14. 4th Law: “There is no such thing as a free lunch” Everything you do, must have a reason behind it. This law basically means you have to do something in order to get something in return. OR Everything has consequences. For example, a “free” pizza party. In order to win the party, you have to fill out a survey. Survey info gets sold off… you get annoying texts from companies ….

  15. “There is no such thing as a free lunch” This ecological law embodies the previous 3 laws. Because the global ecosystem is a connected whole, in which nothing can be gained or lost, • anything extracted from it by human effort • must be replaced. • Payment of this price cannot be avoided; it can only be delayed.

  16. Hidden Costs Things may seem free, but have hidden “costs”. • Free phones with a 3 year plan.  • Free samples at grocery stores.

  17. “A shocking 45 percent of all land on Earth is today used for raising livestock and growing crops to feed them. But most land used for livestock and crops can grow trees instead. - Robert Goodland, World Bank Group environmental adviser 4th Law: “There is no such thing as a free lunch” Livestock’s carbon footprint ‘catastrophic,’ say climate expertsRead full article… World Watch magazine reported that 18 percent of worldwide greenhouse gas emissions attributable to livestock -cattle, buffalo, sheep, goats, camels, pigs and poultry (chicken) and their byproducts actually account for at least 32.6 billion tons of carbon dioxide (CO2) per year, or 51 percent of annual worldwide GHG emissions It takes about 12,000 liters of water to produce one kg of beef, compared with just 850 liters to produce the same weight of wheat.

  18. PLANETIN PERIL

  19. Why does DEFORESTATION have such a huge impact on the ecosystem? Why is it so important to save our TREES? 1st and 2nd Law Why should we limit the use of FOSSIL FUELS(carbon-based)? 4th Law How is CARBON cycled in your E-column? 1st and 2nd law

  20. LIMITING FACTORS factor that controls a process, such as organism growth or species population, size, or distribution. CARRYING CAPACITY is the population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment.
