Imagine an attempt to restore a clear cut forest to its previous condition, resurrect extinct species of plants or animals, or rebuild a destroyed city. We do not have the tools, resources and knowledge to do this. Our current path is a path of destruction. We have enough brains to develop technology. However, we do not have enough brains to use it properly and to protect environment and ecosystem.
Scientists are well educated.
Some are but many are not. Education means a good back-ground in a particular discipline, broad understanding of other disciplines, independent thinking, high levels of integrity and ethical standards. Many educational institutions have gone for quantity rather than quality. Scientific discoveries and vision require a combination of broad background, creativity and integrity which one can seldom find these days. Morality and integrity are not a part of the curriculum at most universities.
