Nuclear Power
Nuclear power provides 17 percent of the worlds power. In America it provides 15 percent is nuclear power. Nuclear power works mostly like any other power source. The nuclear fusion creates heat, which evaporates water. The steam spins turbines which, in turn, powers generators, creating an electrical current. The advantages of nuclear power is that there is not that much pollution. But the waste afterwards is a very toxic damaging thing. And if the power stations have any problems the damage is devastating.

He song says many untrue things. The earth does not revolve at 900 miles an hour, it revolves at 1,040 miles per hour. Also, not everything in the universe move at the same rate, or spead. SO we do not all "move a million miles a day". The universe is 156 billion light years wide. Not 3 thousand light years wide.
Hamburgers
The amount it takes to make one fast food hamburger is amzing. On the average each ingrediant has to travel 1,200 from the producer to the consumer. The amount of corn feed to the cow comes out to 1.2 pounds of feed adds a quarter pound of mucsle tissue for the paddie. So for that one small p[addie it takes 1.2 pounds of corn. That corn takes up six square feet. That is six square feet of land for one paddy. Then there is the bun. After all the processing, it took two square feet of wheat to make one bun for one burger. And then there are all of the condiments and vegatables. All of those came from multiple states and regions around the country.
