TERRE HAUTE —
Moving toward sustainability
As we read about last Sunday’s Earth Day observance, I make note of a study published recently in Environmental Research Letters which warns that animal manure and fertilizers used in growing animal feed emit large amounts of nitrous oxide, a powerful greenhouse gas. An op-ed piece in last week’s New York Times warns that the devastating environmental impacts of a meat-based diet are actually magnified when raising animals on the range, because this involves much more land and more greenhouse gas emissions.
These conclusions are in keeping with an extensive United Nations Environment Program’s report which drew on dozens of smaller studies. The highly respected report concluded that agricultural production accounts for 70 percent of global freshwater use, 38 percent of land use and 19 percent of greenhouse gas emissions.
In an environmentally sustainable world, meat and dairy products must be replaced by vegetables, fruits, and grains, just as fossil fuels must be replaced by wind, solar, and other pollution-free energy sources. As the world’s most conspicuous consumers, we have a special obligation to lead in pursuing an environmentally sustainable lifestyle. Our next trip to the supermarket is a great starting point.
