Plant life on our planet soaks up a fair amount of the carbon dioxide that pours out of our tailpipes and smokestacks. Plants take it up during the summer and return some of it to the air in the winter. And a new study shows that those "breaths" have gotten deeper over the past 50 years.
This isn't just a curiosity. Plant life is helping to reduce the speed at which carbon dioxide is building up in our atmosphere. That's slowing the global warming, at least marginally, so scientists are eager to understand how this process works. The new study provides some clues.
Until two years ago, Myanmar, also known as Burma, was ruled by the longest-running military dictatorship in the world. In 2010, the military began to loosen its grip on the country, increasing civil freedoms and offering some political and economic opportunity for citizens.
But some are wondering whether the country can truly transition to democracy if it fails to reconcile with its brutal past.
