The worldwide decline in the population of bees and other pollinators has impelled farmers to do what they can to encourage and nurture bees on their land. Protecting bees is important because pollinators are essential for growing many foods including coffee, cacao, almonds and many other fruits and vegetables.
There has been lots of discussion about the decline in bee populations and its dire consequences for agriculture. We have also talked about the efforts to save the monarch butterfly, whose numbers have been dropping dramatically over the years. But the rest of the insect world does not get much attention. For the most part, we think of insects as a nuisance or as potential pests.
One of the most notable success stories in recycling is that of structural plastic lumber. The material is mostly polyethylene reinforced with stiff plastics or recycled composites. Made from milk containers, coffee cups, and other recycled plastics, structural plastic lumber is lighter than steel, longer-lasting than natural lumber and strong enough to support 120-ton locomotives.
