There are scarcities in drinking water when you pollute the groundwater with nitrates. There is a scarcity in diversity when you create huge cornfields with the same strain of corn so that when one disease strikes - which happened in the United States in the 70s - all the cornfields in the country are wiped out. That was the first time the U.S. realized the value of diversity in agriculture and began to discuss genetic resources and their conservation.

My personal background is actually very unusual for the kind of career I chose. I didn’t meet anyone who had ever done physics in my life. I grew up in the Himalayan forests. My father was a forest conservator, which meant that if I wasn’t in school I was in the forests with him. That has been very largely responsible for my ecological inclinations.
