I am not opposed to man's using nature to man's benefit, within the bounds of rational self interest (not violating property rights; and thinking and acting for long term goals, not just short term goals at the expense of the future). For example, I have no problem with the building of a dam, if the land it will affect belongs to the dam builder (and hopefully that person will take into account that the environment might be negatively affected by his damn and might negatively impact his future plans, but that is the problem of that person only).
But
this article tells how the government messed up the environment (i.e., long term goals were not properly planned for, if at all) by building a dam, and now the government wants to interfere more to try to fix it: "Officials hope" that what they are doing will help. They (people with a "government" mindset) simply do not learn that there are unintended consequences when playing with a complex system. In this case, I'm not even talking about the free market - the environment is incredibly complex as well.
