When I was in Beijing, I often took a walk in the evening with my sister. We often met people on the street. My sister commented, I bet there aren't that many people on the street in America.
I told her, here are the differences between walking outside in two countries. First, in America I never go out alone after dinner, especially in New York City. Safety is my top concern when it's dark. Second, true some places are very empty, too much so that you wish to see a human around, especially in Kansas.
Third, there is something very annoying, even agonizing and damaging in America that you seldom see in Beijing, that is, lawn mowing. Today is Monday, the worst day to go out in our neighborhood. You bump into one of them no matter where you turn. It's ear-deafening and air-toxic.
American lifestyle is definitely extravagant, non-sustainable and environmentally damaging due to the air and noice pollution caused by lawn care activities. The high-maintenance lawns pollute the air as much as the car.
According to Princeton University Climate Action team, America has over 40 million acres of land covered by lawn. The gasoline powered lawn mowing machines and lawn fertilizers contribute significantly to carbon emissions. Americans should consider alternatives for the structure of their lawn. I saw this alternative in many parks in Beijing, where they grow low maintenance tall grass.
It almost seems hopeless to make a change to some entrenched societal norms and consumer behavior like lawn structure in America, especially when it involved colossal profits for businesses. It takes a combination of technology advances, regulatory changes and a collective will to bring about changes in consumer behavior and lawn structure, like using electric lawn mower, or having regulatory enforcement prohibiting gas machines.
As it is now, most Americans are blissfully ignorant about this simple fact. The world has no reason to be optimistic on this.
