Pastured vs. Free-Range vs. Cage-Free vs. Organic Eggs—What's The Difference? —
Dee McCaffrey says the problems with conventional eggs range from low-quality feed to inhumane growing conditions. Organic eggs use better feed and have better growing conditions, but access to outdoors is sometimes more theory than practice in large organic operations. She rightly promotes eggs from backyard chickens as the best choice, with eggs from pastured chickens another good way to go.

Lakes Turning to Jelly —
The problem of acid rain is often touted as one of the few success stories in controlling pollution, as the industrial emissions that cause it have been cut substantially. But the environmental damage and disruption caused by acid rain still echo in the wilderness. One example discovered is the "jellification" of temperate lakes, where acid rain has reduced calcium content, an essential element for most lake organisms. This has caused some crustaceans at the base of the aquatic food chain—the ones that make their exoskeletons from calcium—to be at a disadvantage, and they're now being displaced by species that have a jelly-like coating. These jelly organisms are inedible to many predators and thus are disruptive to the lakes' ecological balance.
