Who Am I

I am David Marinelli. I research human ecology, wilderness as non human social order, sustainability, biodiversity and solutions to stop habitat degradation and extinction of non human species.


Think of the rain and the sea that provide the water you drink
Think of the air you breath provided by the oceans and trees
Think of the food you eat that one way or another comes from the soil and its nutrients
Think of the place you live in that is made from rock and ores from Earth’s crust
Think of the ground you are standing on, that is Earth’s crust
Think of all the species we share this Earth with and the common parents we shared with them hundreds of millions of years ago, and without which your biological body would not be standing here today
Think of this oasis of life, Earth in a solar system, afloat in a galaxy with 11 million suns, one is ours, amongst countless galaxies in the universe, our only home, made friendly and hospitable for us by nature

We owe a debt of gratitude and allegiance to the natural world
