The video below is well worth 28 minutes of your time.
Dr. James Lovelock is as correct and as prescient as ever. Gaia has been unquestionably proven (thus it's a theory and no longer a hypothesis...) and, as he mentions, is just called another name by modern bio/eco/geological science ("Earth Systems Science", specifically)... Pay attention and hopefully you'll learn a few things that are independent of Climate Politics (even if you disagree with an environmentalist who supports nuclear energy and questions the impact of some currently popular alternative energy resources - or if you disagree with "Climate Change"...).
Open your mind. Listen.
The Earth is a system of systems and to ensure our species will continue as an inhabitant for as long as possible, we'll need to work on solutions to counter and prevent positive feedback loops - amplification of processes that negatively impact the overall stability and resiliency of the Earth System, Gaia, effectively "injecting" negative feedback versus positive.
We are the chaos monkeys of planet Earth. This is true. Yet we are also the conscious of the Earth - its eyes and ears - as Dr. Lovelock so clearly states. Through our intelligence, itself the result of billions of years of evolution, the Earth has for the first time achieved a level of self-awareness that it can recognize itself for what it is - a self-sustaining planet, where biological systems benefit from the planet's conditions which support life and effectively maintain these conditions over time via the actions associated with living (algae producing clouds over the oceans, the oxygen and carbon cycles, etc...)....
We are not a plague or a virus or a cancer..., but more so we are a biological system that tends to add chaos to an already highly resilient system of systems (in part because of our level of awareness and intelligence - an incredible irony indeed...), in which we are inextricably tied (after all, we aren't only "made of stars". We sprung from this planet like everything else that lives here...).
We can do the right thing for our future, but we will need to work out some critical mental flaws in addition to inventing technologies and promoting/regulating behaviors that will limit the global affect of the chaos we tend to create.
