Plastics are the ubiquitous workhorse material of the modern economy. Their use has increased 20-fold in the past half century, and production of plastics is expected to double again in the next 20 years.
Estimates are that as much as 40% of produce in America is wasted. We throw out fruits and vegetables for a variety of reasons, but one of the most unfortunate is when produce is tossed simply because it doesn’t look good enough. Misshapen tomatoes, lumpy carrots, double-lobed potatoes, and crooked cucumbers end up in the waste bin instead of on our plates.
We have talked quite a bit about food waste and in particular its impact on world hunger and on the economy. The world wastes more than $750 billion worth of food each year and 1.6 billion tons of food is left in fields, sent to landfills or scattered about the landscape. Another 7 million tons of fishery discards are dumped in the sea.
Paper or plastic? It’s a quandary we have faced in the grocery store for decades. Plastic is non-biodegradable and usually ends up in landfills or worse, in waterways or in the ocean. On the other hand, manufacturing paper is water intensive and produces pollution.
Our national parks are shining examples of the American wilderness whose natural wonders attract millions of visitors from around the world. This popularity has a cost: national park visitors generate more than 100 million pounds of garbage each year, most of which ends up in landfills.
