I think that the main thrust of Michael Crichton's piece is that living systems are inherently complex, and that we (humans) think and try to implement simple solutions; and then are confounded when they don't work, and/or give us unintended consequences.
First off, in his article, remember that he made references that someone perceived a problem, real or otherwise and that the media went to town on it, appealing to the "masses" through fear to motivate them/us. I'm 50 years old. When I graduated highschool, (1976) the new fear (The sky is falling, the sky is falling; oh sh*t we're all gonna die) was global cooling and the comming ice age. Now, of course, it is global warming and coastal innundation... and yes, "oh sh*t, we're all gonna die. Total and utter reversal in 30 or so years. Then there was "Beef fried on a 350 degree griddle causes cancer"... evidently that one died a quiet death. Then there was (oh yes, it's true) "Mother's milk causes cancer" (Who CAN you trust?); coffee causes cancer, followed some years later by "coffee has beneficial effects"... "red wine's deadly effects" followed by "red wine's beneficial antioxident qualities"; I guess one of the ones I'm waiting to be repealed was how wonderful movie theater popcorn tasted 20 years ago before somebody "discovered" that it being popped in whatever the oil du jour was (I think it was coconut oil), was gonna kill us dead, and it was switched to whatever the hell they pop it in now. Look, 40 years ago, sugar in softdrinks was going to rot our damned teeth out, and make us all into blimps. So we got rid of it (what did that do to the sugar industry?) and turned to Cyclamates... oops, carcinogen; somebody, probably Cargil or Archer Daniels/Midland, came up with corn-syrup, and now the incidence of type 2 diabetes is up many-fold; No matter that the human body evolved metabolising cane and other naturally-occurring sugars, now we're ingesting artificial sweeteners, and perhaps not doing it so well. You Southerners may recognise some of these... Kudzu was imported from Japan, and widely planted in the South to control erosion, and has wiped out large areas of native plants. Nutria, simillar to muskrats, were introduced to pelt farms in the South in the South and earlier, but when the market went south for their furs, they got "out" or were released, and have gone on to damage aquatic vegetation and human structures. Oops.
There are dozens of other examples where we change one variable thinking that it will solve some problem, real or immagined, and it does something entirely different.
Crichton may not have been entirely correct, but he should certainly have you thinking that the NEWS you read tomorrow may not be entirely correct either.
