We must scrutinize individual cases with regard to these amphibian population declines and deformities in an attempt to explain whether any particular population is changing, and if so try to explain how, while working these identified mechanisms into systematic models. Researchers must commit to providing long-term monitoring and rigorous investigation of the causes of declines in the especially sensitive amphibian component of the aquatic and terrestrial ecosystems worldwide. We need to move forward with multi-disciplinary research that recognizes the value of animals as sentinels of environmental health. We also need to recognize that environmental protection measures which protect animal health often directly and indirectly protect our health as well. As you got older and wiser, you learned more and more about the boundaries of your world, and you got more and more used to thinking within those boundaries.
Most people look for solutions within the known.
If there is something you want to do, and you think it impossible, I want you to look outside the known, not within it. I want you to learn to think beyond your thoughts. O'Brien, D. J., Kaneene, J.
