Gus Speth, a US advisor on climate change said:
“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.” (Ref: http://winewaterwatch.org/2016/05/we-scientists-dont-know-how-to-do-that-what-a-commentary/)
