Enormous wealth... what would you do with it?

[bocablkr]

I would put the 10 billion in a trust fund. Hopefully, it would make around a billion a year in interest.

I would then do something selfish like use the money to buy up land to protect it from development forever. I would also help all the wildlife preserves in Africa that only need a few hundred thousand a year to run but are in danger of being shut down because even that is too much for their countries to support.
