Nuclear energy contributes a very small amount of emissions into the atmosphere which can cause many environmental problems such as global warming. Uranium is not burned in a nuclear power plant as coal is so there are no emissions from it.
Info on the 2017 USPS Postage Rate Increase. The U.S. Postal Service (USPS) will implement new postage rates for several mailing and shipping products on Sunday, January 22, 2017. Summary of the 2017 Postage Rate Increase: First Class Mail Letters (1 oz.) rates will increase from $0.47 to $0.49 when purchased at the Post Office. Each additional ounce will cost $0.21.
Mr. Carr is not entirely correct. The USPS issued a global forever stamp that pays the first class postage for an ordinary letter weighing not more than one ounce to anywhere in the world. This stamp was introduced in 2013 and sold for $1.10, the rate current at that time. Now this stamp will cost you $1.15, but if you buy them now, when the rate increases, they will still be valid for the full postage rate at the time.
