Remember you are made of dust and will be dust again.
Gn 3:19

Most of the luxuries, and many of the so-called comforts of life, are not only not indispensable, but positive hindrances to the elevation of mankind.
Henry David Thoreau, Walden

One of history's few iron laws is that luxuries tend to become necessities and to spawn new obligations. Once people get used to a certain luxury, they take it for granted. Then they begin to count on it. Finally they reach a point where they can't live without it.
Yuval Harari, Sapiens: A Brief History Of Humankind

At higher atmospheric concentrations, CO2 stops us from thinking clearly. The crisis of global warming is a crisis of the mind, a crisis of thought, a crisis in our ability to think of another way to be. Soon, we shall not be able to think at all.
James Bridle, New Dark Age
