A painless method to reduce the human impact on the environment is to stop mowing grass.
In general, the only reason for mowing is appearance, and often, considering the location of the grass, the appearance can only be appreciated by a small number of people. Moreover, once people get accustomed to seeing uncut lawns, they may consider them preferable.
The mania about cutting grass has reached insanity. Many municipalities in the US have laws forcing people to mow their lawns, and people actually go to jail for not cutting their grass.
But my focus here will be the environmental impact.
The longer the grass, the more leaf area there is per land area. Therefore, uncut grass would be more efficient per unit land area at converting CO2 to oxygen =96 directly reducing the CO2 in the atmosphere.
Lawn mowers have highly polluting small engines. In one estimate, one hour of typical mower engine time is equivalent to an 100 mile trip in an average car
Most mowing is in urban areas, where pollution is the worst and where most people breathe.
The habitat of many animals is disturbed by mowing.
It=92s also worth mentioning that numerous accidents, many serious, are caused directly or indirectly by mowing.
