CefTon A pre-cautionary tale & 8 By Jeff Hammersmark fter some feedback from the Other Press staff, as well as some personal reflection, I will this week begin to guide this column in a new direction. As I said last week, I am not a scientist. Since I do not (yet) have the credentials, authority or reputation to make any science-related claims without referencing, I will be writing hereafter on the assumption that readers of my column will take it upon themselves to access the massive amounts of available information on the topic at hand, and form their own opinions. That brings us to today’s topic, something called the “precautionary principle”. Wikipedia describes it as stating “if an action or policy has a suspected risk or causes harm to the public or the environment, in the absence of scientific consensus that the action or policy is harmful, the burden of proof that it is not harmful falls on those taking the action.” A good example of this is Canada’s action on Bisphenol-A, or BPA. This is the substance found in many plastic products, as well as in the lining of many canned foods, that Canada recently declared toxic and banned in baby bottles. 12 Some studies argue that BPA in products are Causing us harm, and others say that the levels we are exposed to are safe. Canada, whether it is conscious of it or not, has used the precautionary principle to declare BPA toxic, and has started to ban it from certain products. What Canada has basically said is even though there is no scientific consensus that BPA is harmful, since those that produce and utilize BPA cannot prove that it is not, we cannot allow it to be an ingredient in baby bottles. When it comes to the environment, specifically climate change, the heart of this principle is easy to apply in that we should not be using a lack of scientific consensus as an excuse not to take steps to prevent it. 1 would argue that there is absolutely a scientific consensus on climate change, and that it is primarily interest groups and industries that want you to believe otherwise. For argument’s sake though, let’s say there is no consensus. On one side, we have people saying if we do not change our ways, the Earth will warm at geologically lightning fast speeds, global sea levels will rise, desertification will become rampant, and so on. On the other side, we have people either saying that this will not happen, or that it will happen, but humans are not causing it. The precautionary principle tells us that it makes more sense to take action against even the chance of climate change panning out as predicted, rather than to claim there is no consensus and therefore do nothing. If we do nothing, there is a chance we could run into serious trouble and have done nothing to stop it. If we take action, we could prevent something very bad from happening, and even if we were wrong and the action was not required to stop climate change, at least Manhattan is not underwater. If someone wanted to play devil’s advocate, they could claim that the precautionary principle can be used to argue against action to stop climate change. Some proposed methods of action would make major changes to the economy, which some argue could potentially cause dramatic negative effects on society. That is a fair use of the principle, but there is only so much that we can do as individuals that would allow us to stay true to the principle, while effecting real change. The sum of individual actions can be substantial, and that is independent of any major changes to the economy. Who is it going to hurt if you recycle, buy locally grown produce, walk to the store instead of drive, or eat a little less meat? When it comes to industry, simply working to become more efficient in the workplace or using fewer natural resources where possible can have a huge impact. Reducing office paper consumption, and using the money saved to buy partly or fully recycled paper won’t bring the economy to a crashing halt, but it will save a lot of trees, and keep demand for recycled products up (a good example of how individual actions can trickle up and effect change at higher levels). Right here at the college, we’ve surely saved a huge number of trees since we implemented our double-sided printing policy. Many people are saying that immediate and dramatic action is needed to stop climate change, but until society at its highest levels comes to an uncontested consensus on climate change, what harm will it do for you to do everything you comfortably can to reduce your personal environmental footprint? The worst that can happen is that you’ll tread a little lighter on the planet, possibly even save some money, and in some cases, improve your health and well being. Not a bad deal for being precautionary.
