3 Ecological Footprint A measure of human demand on the Earth s ecosystems. Measures how much land and water area humans use. Also takes into consideration the resources used from those areas. Finally, looks at the waste left behind from using those resources. All compared to how fast nature can replace the used resources and clean up the waste that was left behind.

12 Facts (WWF 2013) 1) In the next 40 years, we have to produce as much food as we have in the past 8,000. On a finite planet with dwindling land available on which to farm, scaling up food production at this rate requires doing more with less.

13 Facts (WWF 2013) 2) Americans waste enough food each year to fill 91 Empire State Buildings. Globally, we waste a third of all food produced. Eliminating waste would effectively halve the amount of new food needed by 2050.

14 Facts (WWF 2013) 3) It took China just 12 years to double its per capita gross domestic product; it took India 17 years. Compare this to the United Kingdom (155 years) and the United States (53 years) and you start to grasp the unprecedented pace with which developing markets are growing.

16 Facts (WWF 2013) 4) By 2050 about 70% of the world s population will live in cities, nearly as many people as are alive today. The typical urbanite uses more water and consumes more meat-laden diets than their rural counterpart. At the same time, a third of the world s population is already affected by water scarcity for at least one month each year, and this figure is increasing.

17 Facts (WWF 2013) 5) Four crops corn, soybeans, wheat and rice comprise about 75% of the caloric content of food production worldwide. With the ever-present threat of weather variability due to climate change, a single drought or extreme weather event can have drastic impacts on global food supplies, and consequently, the prices we pay. It s time to consider gleaning more calories from crops traditionally neglected by food producers like cassava, sweet potatoes and amaranth.

18 Facts (WWF 2013) 6) Farmed shrimp is the most valuable food commodity in the world. Aquaculture is the fastest growing food producing sector. More than half of the world s shrimp now comes from a farm. Considering the average annual per capita consumption of shrimp in the U.S. is around four pounds, and that 85 percent of the world s marine stocks are either fully exploited or overfished, responsible shrimp aquaculture can help save the world s oceans.

19 Facts (WWF 2013) 7) Globally, forests are lost at a rate of 36 football fields per minute. Growing demand for forest and agricultural products coupled with unsustainable practices and poor legal enforcement is at the root of this troubling trend. Forests are the lifeblood of our planet and nearly half of Earth s original forest cover has been lost.

20 Facts (WWF 2013) Over the past few decades, humanity has consumed 50 percent more resources than Earth can provide. If we keep spending like this, by 2030, even two planets will not be enough.

21 Comparative Values Can measure your ecological footprint, impact on the Earth and its resources, or measure a community, city, province, country, or on a global scale. Compare and see resource uses around the world.
