John, I know that this forum is to discuss tin whiskers, but I can't ignore your stated intention to donate to an environmental activist organization. There was a time when such organizations did more good than harm. The result was that they pretty much worked themselves out of a job. Few organizations choose to dissolve themselves, so instead they began having to create issues that would keep the contributions flowing in. It was good for them to promote removal of lead from gasoline and paint. It was not good for them to promote removal of lead and the other prohibited elements from electronic products. In doing so they did not follow their own precautionary principle (requiring proving that a proposed substitute is safer than what is now being used), and they did not conduct any kind of environmental impact analysis. They did no epidemiology to show that their chosen bogeymen were causing any kind of health problem attributable to their use in electronic products. Had they bothered to do so, they would not have found any cases of poisoning due to this cause. Their continued attempt to force removal of brominated flame retardants from electronic products (despite the proven safety of deca-BDE and TBBPA) would, if successful, result in deaths by fire. There is one thing that environmental activist organizations are very good at - publicity. Sadly, they are not good at being honest in their claims. Environmental activist organizations love to talk about corporate social responsibility, but by crying "wolf" where there is no wolf they have behaved quite irresponsibly. They love to talk about the greed of corporations, but by deliberately misrepresentating risk to promote their own cash flow from people who believe them they have behaved very greedily. Don't miss the point - the EU legislators enacted RoHS because they too were misled by these organizations, or because they were frightened of being labeled "anti-environment" by them. Think "demagoguery." It appears that these organizations have misled you into believing that - apart from Pb - the use of the prohibited substances in electronics is not a good idea. Please, in your course, emphasize that what you are teaching is solely a result of legislation and not because following what you teach is going to make the world healthier. Before you make any such claim, investigate for yourself. Please don't just depend on organizations who have a financial stake in what they tell you. Their "pointless exercise" of elemental analysis of a laptop indicates that they just don't get it. And now they want to ban the use of petrolatum, which in the US is sold in drug stores as "Vaseline." The organizations also favor getting governments to force people to pay for regulated recycling of electronic products, despite lack of evidence that such recycling will save even one life, or that it will improve the standard of living enough to offset the reduction in the standard of living caused by having to pay the tribute they demand. Over the years I have published on the IPC Leadfree forum roughly two hundred essays discussing these topics. You might want to go to the archives to review "Misleaders, misled, and victims, and how to deal with them," posted on August 14, 2001. As for decrying third-world unregulated practices in recycling electronic products, their efforts have been and will continue to be ineffectual. Here also they have done no environmental impact analysis. Yes, it's obvious that their practices pollute the immediate environment, but those practices do give a living to some very indigent people. In any case, in spite of all the publicity that has been given to the problem, the solutions offered by environmental activist groups have not been effective. It's unlikely that giving them more money to lobby for more recycling controls will improve things. The third world is a very big place, and resources spent in looking for smugglers and polluters are resources not spent in dealing with other much more pressing problems - like providing safe drinking water. Since you want to improve the health of the planet, why not consider an organization that is trying to eradicate malaria? There are many orders of magnitude more people dying of malaria (due to environmental activist organizations working to prevent the use of DDT) than are having health problems due to unregulated recycling of electronic products. Paul Driessen, author of Green Power - Black Death estimates that fifty million people have died because of rules (put in place as a result of activist efforts) that made DDT unavailable to them. Reading that book will make you quite unlikely to want to donate money to any environmental activist organization. Gordon Davy
