To be sure,  the subject of illegal immigration is a hot topic in the world of politics.  But did you also know it is a hot topic in the world of ecology?  Well for years, scientists and biologists have been trying to figure out how to stop the spread of invasive foreign species – species which have contributed to the decimation of 70 percent of native aquatic plants over the past 100 years.  Now it appears there’s a new technology, called deoxygenation, that may help solve this problem.  By simply pumping nitrogen gas in the ballast tanks of ships, studies reveal this process can kill most invasive species in just a few days of ocean travel.  Since the process also helps curb corrosion, this is one new technology that’s clearly worthy of a green card.
