A Carbon Sink Larger Than New York State Found in Central Africa

New scientific mapping has revealed the world's largest carbon sink in a peat swamp in the Congo Basin in central Africa. The swamp, measuring larger than New York State, is estimated to contain the equivalent of 20 years worth of U.S. greenhouse gas emissions in carbon—roughly 30 billion tons or 30 percent of the world's peatland carbon reserves.

Scientists emphasize the need to keep this peat forest intact and protected from agricultural developments in order to keep the massive amount of carbon in the ground.

"It's astonishing to me that in 2017 we can be making these kinds of discoveries," said Simon Lewis, a professor at the University of Leeds in England and author of a the study on the peatlands published Wednesday in the journal Nature.

High up in the mountains of Montana's Glacier National Park, there are two species of insect that only a fly fishermen or entomologist would probably recognize. Known as stoneflies, these aquatic bugs are similar to dragonflies and mayflies in that they spend part of their lives underwater before emerging onto the land, where they transform into winged adults less than a half inch long. However, unlike those other species, stoneflies do their thing only where cold, clean waters flow.

The year is less than four weeks old, but scientists already know that carbon dioxide emissions will continue to head upwards — as they have every year since measurements began leading to a continuation of the Earth's rising heat.

Each year, an estimated 600 million people worldwide experience a foodborne illness.

While there are many causes, a major and preventable one is cross-contamination.
