No Action Is Without Its Side Effects.

Perhaps One Of The Most Meaningful Ways To Sense The Impact Of The Environmental Crisis Is To Confront The Question Which Is Always Asked About Lake Erie: How Can We Restore It? I Believe The Only Valid Answer Is That No One Knows. For It Should Be Clear That Even If Overnight All Of The Pollutants Now Pouring Into Lake Erie Were Stopped, There Would Still Remain The Problem Of The Accumulated Mass Of Pollutants In The Lake Bottom.

Perhaps The Simplest Example Is A Synthetic Plastic, Which Unlike Natural Materials, Is Not Degraded By Biological Decay. It Therefore Persists As Rubbish Or Is Burned-in Both Cases Causing Pollution. In The Same Way, A Substance Such As Ddt Or Lead, Which Plays No Role In The Chemistry Of Life And Interferes With The Actions Of Substances That Do, Is Bound To Cause Ecological Damage If Sufficiently Concentrated.

Seen That Way, The Wholesale Transformation Of Production Technologies That Is Mandated By Pollution Prevention Creates A New Surge Of Economic Development.

In General, Any Productive Activity Which Introduces Substances Foreign To The Natural Environment Runs A Considerable Risk Of Polluting It.

The Environmental Crisis Is A Sign That The Ecosphere Is Now So Heavily Strained That Its Continued Stability Is Threatened. It Is A Warning That We Must Discover The Source Of This Suicidal Drive And Master It Before It Destroys The Environment-and Ourselves.
