The most powerful energy source affecting this planet is the sun. Energy from the sun arrives on earth in the form of heat and light. Ultimately the plants and animals that populate this planet absorb this energy in some form or another. Since the first creatures crawled out of the primordial soup they have been consuming the suns energy, some more efficiently than others, which is why they evolved at different rates and into countless forms.
In prehistoric times the planet was sparsely populated. The majority of the plants and animals had evolved into giants in comparison to the creatures that populate or world today. It stands to reason that such huge creatures had huge appetites in order to consume enough resources to provide the energy they needed to function and continue to evolve.
It is generally accepted that these magnificent beasts died out during the ice-age, which may have been caused by an asteroid strike, volcanic eruptions or normal climatic change. Whatever the cause, the result was the same. Energy from the sun was unable to penetrate the atmosphere and the giants it supported were unable to survive without it. The only creatures that did were the tiny ones with meagre resource requirements.
Fast forward to modern times and we find our planet heavily populated, not with giants but millions of smaller species, which have all evolved from the small creatures that survived the ice-age. One of these is known as “Mankind”. Like the giant dinosaurs before us, we still consume energy to maintain our relatively tiny bodies, we just take smaller bites.
With the onset of global warming the earth is absorbing more and more energy from the sun. This energy has to go somewhere and without the giants of prehistoric time the small creatures that remain are the only things that can absorb this extra energy the sun is providing. This process of absorption is manifesting among mankind as an obesity crisis.
If energy absorption by the planet was increasing you would expect all creatures, including mankind, to expand proportionately. However, we don’t all absorb energy at the same rate, just like the dinosaurs, some of use naturally evolve faster than others and fuel this evolution by storing more additional energy as and when it’s available.
I’m not fat, I’m evolving. If you’re not, you’re a dinosaur.
