How to reduce global warming

It came to me in a flash.

There are roughly 7,300,000,000 people alive on planet earth today (actually there are more than that, but I'm rounding to keep things simple) and there are 365 days in a year. Therefore, every single day, 20,000,000 people celebrate their birthdays.

Let's ban putting candles on birthday cakes.

Wasn't that simple?

It might even usher in a new ice age.

I don't know why no one has thought of this before.

Someone should nominate me for a Nobel Prize.
