McDonald’s And Antibiotics


McDonald’s – the world’s largest chain of hamburger fast food restaurants – recently announced plans to source chicken that is free of human antibiotics. The corporation, which is one of the country’s biggest buyers of chicken, is trying to shake its image of offering unhealthy and unnatural foods. The transition to this cleaner meat will take two years.



Designer Wetlands

Drinking water supplies around the world often contain trace amounts of pharmaceuticals, agricultural and industrial chemicals, and other synthetic compounds that can harm reproduction in fish and may be linked to adverse health effects in humans. Many of these chemicals enter the water supply by passing through our bodies, entering the sewage system, and finding their way into rivers and other bodies of water. There are currently no US regulations for medical drugs under the Safe Drinking Water Act, so it is important to attack this problem proactively.



Animals And Earthquakes


There has long been the notion that animals can somehow sense that an earthquake is imminent. The observation is that animals suddenly withdraw and go silent before a quake. While there is plenty of anecdotal evidence for this phenomenon, there has been little solid proof; that is, until recently.



Perennial Rice


Rice is the most economically important crop in the world. It supplies humanity with about a quarter of its calories. Domesticated rice is a short-lived plant that generally dies off after it produces seeds. Rice paddies have to be cleared of vegetation and plowed each year and are highly vulnerable to soil and nutrient loss through erosion, soil compaction and decline in organic matter.



Tough Times For Amphibians


It’s a tough time to be an amphibian. Around the world, millions of frogs, toads, and salamanders are dying from two emerging diseases. The first plague appeared in the 1990s, and is so deadly to amphibians that it is causing what has been described as the most spectacular loss of vertebrate biodiversity due to disease in recorded history.
