Basic Ecotechnology Concepts
Why do we need biodiversity? What does it have to do with us?
In the past, humans were self-centered and believed that their will would conquer nature. Humanity has damaged the natural environment by means of science and civilization for several thousand years, giving rise to some serious after-effects that have gradually appeared. The extinction of species is a strong warning to us. People now generally forget that human existence depends on the supply from the nature, and that our relationship with the natural environment is not only one of exploitation . Once the natural environment reaches a state from which recovery is impossible, humanity's life-support system will no longer be sustainable.
As humans, we should realize that the extinction of any species of butterfly or creature not only symbolizes the degradation of the earth's environment, but it also represents the lowered chances for survival of our descendants. If we can maintain a biodiverse environment, with more wildlife around us, the human race will have more hope for a sustainable existence.
Some people finally started to think about how to reduce humanity’s ecological impact to the lowest level after seeing the natural environment continuously being destroyed under the excuse of development. How could the original appearance of ecosystems be restored? How could a balance be struck between ecology and development in order to achieve the goal of a sustainable environment and sustainable humanity? These questions gave rise to ecotechnology.
In 1938, Seifert from Germany first mentioned this concept. It was hoped that river remediation could be undertaken in a way that was close to nature and a cheap way that maintained the beautiful natural scenery at the same time. The first person to mention "ecotechnology" was H.T. Odum of the U.S.A. His main idea was that minimal
