Michael Ellis

One participant says it this way: "Start with an encyclopedic knowledge of all the sciences, especially botany, biology and entomology; add the ability to articulate this knowledge rapid-fire in lay terms, laced with humorous anecdotes; add an endless energy supply; add rapport with young and old; add genuine love of nature and teaching - Michael combines all these ingredients to enthuse people about nature."

His hat says it all: Be Here Now.
