Evolution: a victim of its own theory

Evolution is the prevailing belief of most scientists and biologists world-wide. The concept that life came from some single cell critters and slowly, over millions of years, they evolved into some sort of fragile life form is attributed to Charles Darwin. His book, The Origin of The Species, goes over much of this in a more biological approach.
In relation to his studies of the Galapagos Islands, he lays the foundation for his theory for the “survival of the fittest.” This is important to understand. When one species is inferior, it becomes extinct or evolves to adapt to the environment. This adaptation is how the dinosaurs turned into birds and how the mammals came to be so prominent during the ice age.
What is so impressive about this is that we now have our environment being ruined by pollution and forests being destroyed by greedy and desperate people. For some reason, ecologists and other people who ascribe to evolution, are very vexed by this. It would follow that the changing environment would trigger some progress in the flora and fauna. However, they want to preserve the forests and save the endangered animals. Don’t they understand that they need to evolve? All of this time and they have not evolved to be more adaptable?
This could only mean that evolution is not relevant. It seems that they doubt their own science. They should be happy that things are changing, but they fear it. What is really happening is that the long held theory is looking as bleak as our environment, and soon it will change to be more religious in nature, or become extinct.
