Beautiful writing. I teach Environmental Science to high schoolers. As an introduction each student receives a ruler showing centimeters and millimeters. I have a circle drawn on the white board that is a meter across. I explain life at least in the form of bacteria is found a mile down in the crust and around 10 miles up ( around the height of storm clouds and weather that affects us). Then I say this zone on an earth the size of the drawn circle is 4 mm. Where humans live is less than 2 mm. I make the point that the activities of life including humans is powerful enough to have huge influences on that narrow band. I also use examples of keystone species whose actions make a positive effect through an ecosystem saying we are the earth’s keystone species and with wisdom , close observation and love we can create the same positive effect giving examples from past human practices, that the biosphere can be more beautiful and alive because of the presence of humanity.
