Scientists, companies and government agencies are hard at work on decreasing greenhouse gas emissions that cause climate change. In recent years, biofuels produced from corn have emerged as a fuel source to power motor vehicles and, perhaps, airplanes.
Take a deep breath. A recent scientific study reveals disturbing loss of ocean oxygen. Unnerving climatic events like this justify ringing and clanging of the bells on the Public Square, all hands on deck.
Scientific research published in the past year has revealed some relatively new and potentially harmful effects that may result from the increase in atmospheric carbon dioxide. An article in a recent issue of Science News raises concerns that rising carbon dioxide levels may steal some crop nutrients.
Costa Rica, a ‘green republic’ known worldwide for its efforts to protect forests, had poor track record when it comes to deforestation. Costa Rica was once 99 percent forested, but forest cover had steadily diminished.
