Today's Topic

Last month, a floating dock from Japan washed ashore in Newport, Oregon, bringing with it over 20 different types of invasive species, including brown algae, mussels, and crabs. Although scientists stopped the intruders from establishing themselves on the West Coast, the introduction of these species could have been disastrous. Invasive species cause an estimated $100 billion in damage each year in the United States, and globally the bill is more than a trillion dollars. In addition to causing economic problems, invasive species such as the brown tree snake in Guam and zebra mussels in the Great Lakes can also devastate ecosystems and drive species extinct. Although many scientists see invasive species a threat, others view them as a naturally occurring phenomenon and argue that the term “invasive” doesn’t make sense.

Join us for a live chat at 3 p.m. EDT on Thursday, 26 July, when we chat with three experts on invasive species: What future threats do they pose? How can they be stopped? Or are they just misunderstood? You can leave your questions in the comment box below before the chat starts. The full text of the chat will be archived on this page.
