Science always uses metaphor....

Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year.

I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change. The inertia of humans is so huge that you can't really do anything meaningful.

If we gave up eating beef we would have roughly 20 to 30 times more land for food than we have now.

The credit of advancing science has always been due to individuals and never to the age.

Science cannot tell theology how to construct a doctrine of creation, but you can't construct a doctrine of creation without taking account of the age of the universe and the evolutionary character of cosmic history.

The older generation had greater respect for land than science. But we live in an age when science, more than soil, has become the provider of growth and abundance. Living just on the land creates loneliness in an age of globality.

Wisdom alone is the science of other sciences.
