Ecological Footprints

From Wikipedia: An ecological footprint is a measurement of anthropogenic impact on Earth. (Definition –the amount of productive land appropriated on average by each person (in the world, a country, etc.) for food, water, transport, housing, waste management, and other purposes).  Two fields of science, geospheric and biospheric, measure it. It accounts for the human share of biocapacity. Human activity is a major cause of climate change. In January 2015, anthropogenic climate change and nuclear proliferation were cited in moving the Doomsday Clock ahead two minutes. Since the 1950s, a new geological epoch called the Anthropocene has been proposed to distinguish the period of major human impact.

China is the world’s largest contributor to annual growth in the demand for ecological resources and services, and has been for the last five years for which data is available, according to Global Footprint Network.
The Ecological Footprint of the world – a measure of people’s demand on nature – has begun climbing again after experiencing a 2.1 percent decline in 2009 during the recession, according to Global Footprint Network’s 2015 Edition of the National Footprint Accounts, released today. The world’s Ecological Footprint increased nearly 4 percent in 2010 and nearly 1.7 percent in 2011 (the latest year data is available).
However, excluding China, the world’s Ecological Footprint increased far less in 2011: 0.9 percent. The Ecological Footprint of China climbed 3.6% in 2010 and 5.2% in 2011.
While the Ecological Footprints of many countries declined during the recession, including the United States and Germany, the Ecological Footprints of China and India, the world’s two most populous countries, continued to rise and now comprise about one quarter of the Ecological Footprint of the entire world.
Still, the Ecological Footprints per person of both China and India remain far lower than those of many high-income countries. For example, the Ecological Footprint per person of the United States is more than seven times higher than that of India and nearly three times that of China.
