To celebrate the 50th anniversary of Rachel Carson’s “Silent Spring,” local environmentalist Peggy McGrath is offering monthly essays on Carson’s legacy — and what remains to be done.

In the last essay, I discussed the toxic environment we live in, and the path that got us there. According to the 2006 book, Naturally Clean, “In the United States, we have based most of our decision-making on a system that says an activity is innocent until proven guilty. In this school of regulatory thought, most activities, whether cutting down a tree or selling a certain chemical, are considered OK to do until someone can prove that they’re actually not.

“This legal theory has proven to be quite dangerous from a public health perspective. Instead of protecting our families from harm, the current shoot-first-ask-questions-later regulatory policies of both federal and local governmental agencies and lawmakers tend to favor commercial interests.”

An example of this is the recent decision by our legal system favoring Monsanto’s rights over farmers’ rights. Monsanto sued farmers when Monsanto’s GMO seed was blown by the wind onto independent farmers’ lands. These farmers didn’t want Monsanto’s seed, especially if they were organic farmers. (Monsanto also sued farmers who collected natural seed. Monsanto won this case, thanks to their deep pockets.) So the farmers united to sue Monsanto. But the court, shockingly, upheld the decision that Monsanto was not to blame.

There is another way, different from the one we experience living in the U.S. It is called the “Precautionary Principle.” (Rachel Carson’s writing includes this cautionary principle, although she didn’t use those words.) The precautionary principle was first declared in Stockholm in 1972, reiterated in 1992 at the Rio Earth Summit, reinforced and formally created at the 1998 Wingspread Conference in Racine, Wis. The European Union and Canada follow this principle.

“When an activity raises threats of harm to health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically.”

Simply stated, it is much wiser to be safe than to be sorry.

An example of this principle in action occurred in Huron, Ontario. The community’s governing body decided to ban chemical use on private property lawns. Chemlawn, now TruGreen, sued Huron. The case went all the way to the Canadian Supreme Court. Huron won, based on the precautionary principle. That was in 2001.

An unanswered question is: Why do most of us not even know that this principle exists? Please consider contacting your representatives with this question.

Earth Day celebrations

There were others sounding the alarm, but because of Carson’s poetic, articulate and courageous voice, we have an EPA, Clean Air and Water acts, Earth Day and the environmental movement.

To take advantage of opportunities to celebrate our beautiful and one and only Earth, please take advantage of the wonderful events occurring in Oak Park and River Forest.

Here are two of many:

April 21: Kaiulana Lee’s portrays Rachel Carson in a fundraising event for PlanIt Green, the Oak Park/River Forest sustainability program, sponsored by Seven Generations Ahead. Bill Moyers and others across the world have raved about Lee’s embodiment of Carson’s spirit. Visit for more information and ticket purchase.

April 27-29: One Earth Film Festival. For more information, contact
