Los efectos naturales se explican en desapariciones de estrellas, en choques de cuerpos siderales y en los cambios intensos en los procesos de combustión del hidrógeno solar que tanto influencian la Tierra. Obviamente estos fenómenos están fuera del alcance de las sociedades humanas.

Por su parte, los cambios antropogénicos son consecuencia de la llamada revolución industrial desarrollada a partir del 1734, donde el motor de combustión interna se convirtió en pieza esencial de la producción y estilo de vida, obteniendo su energía de la quema de carbón, gas natural o destilados del petróleo, fósiles durmientes que desde hace 350 millones de años, estuvieron fuera de la dinámica energética del planeta.

Los cambios ANTROPOGENICOS son precisamente los que debemos racionalizar a fin de reducir los efectos nocivos que ya causan sobre nuestra atmósfera en forma que si tardamos pudiera tornarse irreversibles, alterando el equilibrio ecológico vital para nuestras propias vidas.

Hay que sustituir las fuentes de energía por otras inocuas a la naturaleza, como sol las solares, eólicas, destilados de la biomasa, hidráulicos, gradientes térmicos marinos y otros.

Es imposible que el mundo siga consumiendo diariamente: 85 millones de barriles de petróleo, 6000 millones de toneladas métricas de carbón mineral, 3000 mil millones de metros cúbicos de gas natural. Talando 3,000,000 de hectáreas de bosques al año, derrochando trillones de metros cúbicos de agua, agrediendo el aire, produciendo ruidos innecesarios y aniquilando la biodiversidad, teniendo hoy al borde del exterminio, a miles de especies de fauna-flora, tan necesarias como la especie humana, para la paz natural del planeta.
