Science vs. emotion in NJ's river dolphins debate

Here is an interesting story that I came across today, the cold temperatures in the New Jersey area have lead to a dangerous climate for some of the local bottlenose dolphins. There are two main arguments about what to do in this situation. The first argument (emotion) is that we should step in and save the dolphins from these conditions and move them to an area where they can survive the winter. The second argument (science) is that we should let nature take its course and if the conditions of the winter kill the dolphins then it was meant to be.
In this case I see myself siding on the science option in this debate. I feel this way because these cold conditions are only going to come back next winter and we will be faced with the same problem all over again. If we do not step in to help these animals some may unfortunately die this winter but, over time these animals will learn how to better adapt to the conditions so that they can continually survive in their natural habitat.
Humans went through the same exact process over a long period of time, we were faced with challenges and so over time we created natural defenses and mechanisms to deal with the problems that we were facing at a certain point in time. Even in the year 2009 we continue to evolve with new inventions and things along those lines to help us survive with more ease in the world.
A part of me feels that it would be even more cruel to help the dolphins than to leave them on their own to adapt to the area in which they live. If humans jump in to help the dolphins then the animals are at the mercy of the humans for the continuation of their existance. By this statement I mean that the dolphins will rely on human assistance for the rest of eternity if we continuously help them whenever they are facing a new issue. If we leave the dolphins to their own devices there is a good chance that they will adapt on their own and survive.
