“One of the issues that sometimes get overlooked when it comes to conservation biology, is that nothing in nature lives in a vacuum – each species is inextricably linked to a network of other species through a series of ecological interactions, and usually they cannot exist without them. That is something to keep in mind for people who think that if a species was to go extinct, then we can simply “resurrect” them through cloning (that is if we even have the technology to be able to do that.”
 
This quote is KEY to what my blog site is all about. It comes from a Google+ post on fungi and orchids in old-growth forests. Old-growth forests are great testaments to the need for connectivity in Nature that facilitates Her vital energy flow.

Why Do I Write These Essays?

Nothing in Nature exists in isolation. The movement of life’s energy, which originates in the sun, takes place because everything is interconnected and interdependent. Your consciousness of interdependence in Nature means that, every time you engage Nature, you ask yourself how a creature, a plant, yourself, or a natural object is connected to another and to Nature’s greater scheme of things. With this awareness you are prepared to protect Nature’s environment that sustains you. And, you create your legacy by encouraging others to do likewise.

 

If, after reading my essays, you find yourself embracing these ideas, I am thrilled in knowing that I’ve played some small part in setting this world view in motion in your mind.
