Factors outside individual researchers’ immediate control can have a significant impact on the direction their careers take. One of the things that nudged former director of the Stony Brook Center for Biotechnology Glenn Prestwich in the direction that ultimately turned him into a “biotech guy” was a change in federal funding policy in the 1980s. The part of the National Science Foundation that had been funding his work on insect chemical defense and insect steroid metabolism, the Division of Applied Biology, was eliminated. “That meant that two-third of my grants went from a couple hundred thousand dollars a year to zero. That meant that my research group of almost 30 became a research group of eight. I had to refocus.” And that resulted in a very different research trajectory.

Plants need nitrogen to grow, but a significant portion of the nitrogen in fertilizers is not absorbed by the soil or used by the growing plants. Rather, it washes away into waterways, rivers, and the ocean. This in turn has had devastating effects on marine life. In some areas, excessive nitrogen in the oceans has caused algae blooms that kill wildlife, make it dangerous for people to consume fish or shellfish or in some cases even swim in affected waters. This problem isn’t limited to poorer countries. Nitrogen pollution is a serious problem here on Long Island. In our case, the nitrogen comes primarily from septic tanks and cesspools, although nitrogen from agricultural fertilizers also plays a role. Nitrogen pollution in the waters around Long Island has hampered fishing, made it dangerous to eat seafood from some areas, and caused environmental changes that make coastal areas more prone to flooding.
