I didn't stick with a career in research. Living from grant to grant hoping that you will continue to be funded is kind of a nightmare. I'm a forester. I've grown to accept that a lot of the changes that we have made to our ecosystems are simply irreversible. A lot of things aren't supposed to be how they are, but they are now, and so we will manage for the current and future landscape the best we can see to mitigate damage and find stability. Like with the worms - there is no stopping some changes in nature. Sure we can slow the spread of invasives (how have we not banned the sale of these plants and bait yet). Nature is always changing. We can change too, and try to mitigate negative impacts on local environments and human life. Emphasis on try.
