Does anyone have Bill Gates email address - I want to ask him to contribute to find the answer as to why bee colonies are declining.

[email protected]

He does not read his own email, he has people do that for him.

Good Luck.

Why might I ask would Bill gates care about bees?

He's currently the world's most generous philanthropist

Oh?

And I believe there was grant money for this from the US government,
I would assume you have a research lab, a PHD in this science and so on.

I've read that Bill Gates spam filter captures over 1,000,000 posts per day.

Your county extension service will have more info on the bee problem that Bill Gates. Virginia was giving away bee hives to qualfied farmers and gardeners who are interested in trying to jumpstart the population. Check your state's website - maybe they have a similar program.
