When the Europeans first arrived in North America, the average depth of the topsoil was 53.34 cm (1¾ ft) and it was rich in the types of symbiotic organisms necessary for plant roots to absorb minerals from the soil. Today North America averages around 15.24 cm (6 in) of topsoil and most if it is exhausted of nutrients and much is devoid of life.

A species may eat a particular bacterium, phytoplankton, smaller fish, or plant in an area. Lacking a predator, these species/populations will overgrow and alter the area's biology, overwhelming and driving to extinction dozens or hundreds or thousands of other local species.

Many people I've met believe that plants are made up of soil-that the tree outside your house, for example, is mostly made from the soil in which it grew. That's a common mistake.

Ask how you’d live your life differently if you knew you were going to die soon, then ask yourself who those people you admire are and why you admire them, and then ask yourself what was the most fun time in your life.

The most powerful way to change the world is to secretly commit little acts of compassion. You must behave as if your every act, even the smallest, impacted a thousand people for a hundred generations. Because it does.

Because nitrous oxide [released by nitrate-fertilised soil] is 296 times stronger than CO₂ at global warming and methane [cow farts] is about 26 times as potent as CO₂, the combined greenhouse effect of our livestock worldwide is greater than the sum total of all the cars, trains, busses, trucks, ships, airplanes and jets.
