LifeItself

In the last bog , I told you how the law of mass conservation governs the large-scale behavior of Earth's households - ecosystems - that must recycle all mass on average and export only low quality heat into the cold universe.  Now, I will give you a few useful definitions of cyclic processes, sustainability, and ecosystem productivity. Let me start from stating the obvious:  We live in a spaceship we cannot leave, a gorgeous blue, white and green planet Earth that takes us for a spin around her star, the Sun, each year. But this statement is imprecise. We really live on a vanishingly thin skin of the Earth, her ecosphere .   Think of this skin as of a thin delicate membrane, teaming with life and beauty, but incredibly fragile. We trample on this membrane and poison it.  Then we act surprised when it brakes and shrivels. Practically all life on the Earth exists between two concentric spheres defined by the mean Earth surface at the radial distance ...

The essence of my unchanging argument is as follows: An exponential growth of human population can be supported for a while by a similarly exponential increase of production of power as primary energy per unit time and food we must eat each day. After a certain time interval , whose length depends on the rate of population growth and technology, both the population and the means of its survival must stabilize or collapse.  The elapsed time to collapse depends strongly on the rate of deterioration of environmental services of the Earth: abundance of clean air, water, good soil, large healthy forests, and biodiversity in general, as well as on the healthy oceans. Please note the two key phrases: "for a while" and "a certain time interval."  My argument is generally  rejected, because most people focus on the here and now, and forget that a few decades are less than a blink of an eye in history of humanity.  In the more sophisticated circles of "main-stream...
