Can Goats Prevent Forest Fires ?
As wildfires consume parts of California larger than some smaller states, everyone is talking about how we can prevent such disasters from getting going in the first place. One novel approach is to enlist goats. Not as firefighters—although their surefootedness and determination would probably serve them well in such situations—but as grazers to keep the forest underbrush clear of the tinder-like grasses, bushes and small trees that allow flames to jump to the higher forest canopy and get further spread by the wind.
“Goats help prevent forest fires…by eating the dry stuff before the fire season strikes,” says Lani Malmberg, owner of Colorado-based Ewe4ic (pronounced “u-for-ik”) Ecological Services, which uses goats to gradually and naturally remove weeds and return lands to a healthier more natural state.
Recycle Your Old Mattress
A typical mattress is a 23 cubic foot assembly of steel, wood, cotton and polyurethane foam. Given this wide range of materials, mattresses have typically been difficult to recycle—and still most municipal recycling facilities won’t offer to do it for you. But along with increasing public concerns about the environment—and a greater desire to recycle everything we can—has come a handful of private companies and nonprofit groups that want to make sure your old bed doesn’t end up in a landfill.
Filling our Landfills with Bottled Water
The plastic waste spawned by the recent astronomical growth in the bottled water business is significant. Environmentalists especially decry it because the water from our taps is usually as good as if not better quality than what’s inside the bottle (and indeed sometimes bottled water is just tap water). Further, water bottles are not subject to the bottle bill laws that have kept billions of soda containers—made from the exact same petroleum-derived PET plastic packaging—out of our bursting landfills.
Is It Better To Drive An Old Car Or A New One?
Is it better to drive an older, well-maintained car that gets about 25 miles per gallon, or to buy a new car that gets about 35 miles per gallon?
It definitely makes more sense from a green perspective to keep your old car running and well-maintained as long as you can—especially if it’s getting such good mileage. There are significant environmental costs to both manufacturing a new automobile and adding your old car to the ever-growing collective junk heap.
A 2004 analysis by Toyota found that as much as 28 percent of the carbon dioxide emissions generated during the lifecycle of a typical gasoline-powered car can occur during its manufacture and its transportation to the dealer; the remaining emissions occur during driving once its new owner takes possession. An earlier study by Seikei University in Japan put the pre-purchase number at 12 percent.
