Written and Illustrated by Uma Nagendra Uma Nagendra is a PhD Candidate at the University of Georgia and became interested in studying natural disasters since Hurricane Katrina hit her hometown of New Orleans. She enjoys finding creative ways to demonstrate complicated ecological concepts—preferably if it involves running around outside or drawing pictures. When not crawling over downed
Everyone has seen it: a panning video showing thousands of miles of Arctic ice. This is usually followed by that same area now enveloped in water with the obligatory polar bear floating on a miniscule ice float. As polar bears rely heavily on sea ice as protective cover to hunt seals, their main food source,
Plastic is probably the most important material in our lives today. We see it all around us and use it all the time. So much so that we throw away enough plastic waste each year to circle the planet four times. Why do we consume so much plastic? Sure, it makes our lives more comfortable,
If you read the first installment of our ScienceCafé invasive species series, you may have already guessed the name of this topic: Pueraria lobata, or… kudzu! Before kudzu arrived in the states and poison ivy was the only three-leaved vine, times were simpler. No one worried about kudzu invading their yard and killing their plants
Is it right to allocate a portion of our food crops for producing fuel? What the problem really boils down to is energy. In the past decade or so, worldwide biodiesel and bioethanol production have increased fivefold. Worryingly the vast majority of that biofuel originated from ethanol was obtained from corn in the US. This
If you drive longer than five miles in the South, you'll undoubtedly see an abandoned lot covered in kudzu. Up until the 1950s, farmers transplanted the fast-growing vine from Asia to the U.S. to stop soil erosion along roads. Individual kudzu vines can grow more than 100 feet per growing season, easily spreading over the
I will attempt to graze over a topic ubiquitous in the southeast: invasive plants. With over 5,000 nonnative plant species in the U.S., you could say that this is no small problem, whether it is in our hands or not. You may ask yourself: Why should I care about the spread of some obnoxious, ugly
Around mid-summer each year, stories about wildfires, especially in the Western United States begin to dominate the news. Since 2000, there have been between 40,000 to 100,000 wildfires in the U.S. each year that are responsible for an average of 19 fatalities and 7 million burned acres (about the size of Massachusetts). When humans live
