I'm sure your impactful work benefits mankind no end.
His work helps get (and keeps) people employed. Putting food on the table for an unknown number of people and their families.
So, at least in the short term, their work is more important than some jackass screaming "Global Warming! Global Warming!" while jumping up and down with their hair on fire and hoping someone will give them a grant so THEY can put food on the table.
