If lawns are so dangerous, why do so many people believe they are safe? One reason is that advertisers have spent decades telling us that lawns are safe.
In the post-war period, lawns actually were marketed to women. Advertisements persistently positioned lawns as a kind of outdoor extension of the living room. (This is why lawns are so often compared to carpets.) Lawns were depicted as safe, clean places for children to play, and women were told that not having a nicely-mowed lawn was akin to letting garbage pile up inside their homes or failing to cook dinner for their families. So, wives nagged their husbands to mow their lawns, and lawns continued to serve as a visual symbol, without regard to what they actually did to people and the environment.
As described before, people tend to perceive familiar things as safe. At one time, lawns were not common, and most people didn’t know why they would want one – lawns took a lot of work to maintain, and didn’t seem to provide anything in exchange. But as lawns became more common – driven by social pressure, which in turn was driven by images and meanings created by advertising – lawns and their accompanying equipment became normal parts of the suburban scene. People forgot that these things were dangerous, and stopped following safety precautions. More recent generations, who grew up with lawns, may have never been aware of the hazards just outside their home.
But industries haven’t forgotten. Pesticide manufacturers know that their products are dangerous. Lawnmower manufacturers know that their products are dangerous. These industries quietly lobby against bans and regulations on their products, while investing heavily in advertising to tell us that it is insects and tall grass that are the real dangers. In fact, there is very little evidence to support those claims.
Our brains have evolved shortcuts for assessing risk – shortcuts that don’t always work in the modern world, and that can be manipulated by what special interest groups tell us. By paying attention to where information is coming from, and by looking at the real facts regarding risk, we can make intelligent decisions about how to keep ourselves and our families safe.
