"The more we pour the big machines, the fuel, the pesticides, the herbicides, the fertilizer and chemicals into farming, the more we knock out the mechanism that made it all work in the first place"

This quote by David R. Brower is an alerting about the consequences of modern-day farming practices. He is suggesting that by relying too greatly on devices, fuel, pesticides, herbicides, fertilizer, and chemicals, we are damaging the natural systems that make farming possible. He is cautioning us that if we continue to utilize these methods, we will ultimately destroy the very thing that enables us to produce food. This quote serves as a suggestion that we must bear in mind our farming practices and aim to discover a balance between contemporary technology and traditional methods. We need to take care not to overuse these tools and instead focus on sustainable farming practices that will make sure the health of our environment and the future of our food supply.
