As greenhouse gases go, methane is one of the worst. Pound for pound, it is much more damaging to the atmosphere than carbon dioxide. And a good portion of it is emitted by domesticated cattle. Scientists have been working for some time on ways to cut that methane production as a way to help reduce global warming. VOA's Kevin Enochs reports.
The oceans and lakes are full of life, and most of it is not visible to the naked eye. In most bodies of water, every cubic centimeter contains many microorganisms — bacteria, zooplankton as well as single-cell plants called phytoplankton — all of them important links in the natural food chain. Scientists are now using satellites to observe and study these tiny creatures. VOA's George Putic reports.
