Men often act knowingly against their interest.

I do not knowingly kill any living thing - including insects or rodents - and I thank my food for sustaining me.

There are two problems for our species' survival - nuclear war and environmental catastrophe - and we're hurtling towards them. Knowingly.

For years I never knowingly went on a holiday. When I travelled it was for work. Now I am a huge advocate particularly to places which have amazing wildlife such as Antarctica India and Patagonia.
