Description: The Subjection Of Nature To Human Needs
"For the first time nature becomes purely an object for humankind, purely a matter of utility; ceases to be recognized as a power for itself; and the theoretical discovery of its autonomous laws appears merely as a ruse so as to subject it under human needs, whether as an object of consumption or as a means of production."

Description: examples for why sustainability and balance with nature are imperative
"How Nature Helps Us Nature provides us direct benefits and without it we will not be able to survive. Majority of medicines presently in use and all our foods are derived from plants and animals. The cost of over-the-counter drugs from plants alone has been estimated to be about US$ 84 billion worldwide 1. Yet a tiny fraction of biodiversity has been utilized in the allopathic medicines. Similarly in 1997 an international team of economists and environmental scientists came out with a figure of US$ 33 trillion for all ecosystem services provided by natural systems to humanity free of charge. This amount was more than twice the total GDP of the world
2. Ecosystem services include regulation of the atmosphere and climate; purification and retention of fresh water; formation and enrichment of soil; nutrient cycling; detoxification and recirculation of waste; pollination of crops and the production of lumber, fodder and biomass fuel. Even if by magic we get the necessary technology and this much money to provide these services, the physical task will be nearly impossible to accomplish it thereby proving the superiority of natural systems over manmade ones. Besides providing ecosystem utilities, nature also provides us knowledge for our future science and technology. Nature had billions of years of head start and hence it has evolved through infinite permutations and combinations of designs. Since our brains are a product of natural evolution and earth time, it can be conjectured that we cannot think more than what already exists in nature. Thus the fastest way for us to progress is to copy nature. For if we destroy nature we will be robbed of the design template for our further development."

Description: Freely falling objects (i.e. particles moving purely under the force of gravity will "feel" no "pressure", they will not be squeezed, etc. Likewise, a free falling spce shuttle will not "feel" gravity until igniting its thrusts ... If it follows "nature" it will feel nothing. It will only start expriencing resistance once it departures/deviate from the "natural" motion, i.e. the force of gravitation. This was a key insight that led Einstein to discover the general theory of relativity (GR)
"Einstein's theory suggests that it actually is valid to consider that objects in inertial motion (such as falling in elevator, or in a parabola in an airplane, or orbiting planet) can indeed be considered to experience a local loss of the gravitational field responsible for their general motion."

Field of reference: Science
Description: humanity benefits from science and scientific innovations
"... And that knowledge is useful for all sorts of things: from designing bridges, to slowing climate change, to prompting frequent hand washing during flu season. Scientific knowledge allows us to develop new technologies, solve practical problems, and make informed decisions - both individually and collectively. ..."
