We are one with the biosphere
This is not a nature romantic tree huggers story its just straight up telling how it is. We are dependent of the resources and of the ecosystem services in our finite planet for our survival. This means we must respect the laws of the nature. And the laws of thermodynamics rules them all, and everything, EVERYTHING!
The first thermodynamic law states that energy can not be created nor destroyed and the second that entropy (loss of usable energy) will increase (hot coffee gets cold). How come then can we have complex systems like societies you ask if everything degrades and heading for a possible universal heat death?
Ask Blum and Shrödinger and they will explain to you that all living beings can live far away from equiliburim by sucking energy from the environment and giving useless energy back). They are as nobel laurate Prigogine say dissipative structures. And we are all imperalists and the more complex an organism or social structure becomes the more energy it consumes the more useless energy it leaves behind.
Oh there is another quite important thing that together with the laws of nature have a big impact on our and our fellow species life. The number of planets we have at our disposal are finite. We are living on a finite planet. Earth is a partially closed system as the sun presumably will produce usable energy for us billions of year.
Human societies with its technosphere and other ecosystems are subsystems functioning within a bigger partially closed system, the planet. A long time ago in a planet far far different from what we are now inhabiting the effects of our living were mostly spread and felt locally.
However our human societies have grown in size, complexity and impact and we have especially since the beginning of the industrial revolution started to overwhelm the planet, the biosphere we all depend on, by sucking up more negative entropy and leaving disorder (entropy) in the dust of what some predominately white folks have called development.
Today we can more easily see that we apart of this system called earth and we affect each other whether or not we acknowledge it or not. CO2 emissions is a famous example. On planet spaceship development becomes a zero sum game, and that thing some called development, became others misery. If we all affect each other and the planet we all depend on, tangled up in the web of life, would it be much to ask if all of us took our fair share of responsibility in protecting our delicate spaceship and our survival at the same time?
Together with the thermodynamics laws a finite planet (partially closed) creates limits. Limits that affect everything from the complex process that lets leaves that create oxygen and energy to complex structures like human societies, EVERYTHING! Limits are scary as they reminds us of the biggest limit of them all. Death! Limits however is also what connects us human beings and the rest of the biosphere in what is called LIFE!
