Fg shops for 1b to recharge drying lake chad

I think there may be a few issues with your statement.

Firstly, "fg" is not a person or entity that can shop for anything, let alone buy 1 billion (1B) to recharge a lake.

Secondly, Lake Chad is a real lake located in Central Africa, and it is indeed facing a severe drought and water scarcity crisis. However, it's not possible for anyone to buy 1 billion to recharge the lake, as water is a natural resource that cannot be purchased.

Lastly, even if it were possible to buy water, 1 billion would not be enough to significantly recharge Lake Chad, which is a massive lake covering an area of approximately 1,350 square kilometers (523 sq mi).

If you meant to say that someone or an organization is working to recharge Lake Chad, I'd be happy to help you with that information.
