Mother Necessity

“Necessity is the mother of invention" I think this phrase means that whatever we need in life, or whatever is necessary, we'll be able to invent it. Another meaning it has is that whatever we will need in life; someone will be able to make it. Its like Mother 'Necessity' will give birth to new inventions.
1) Cell Phones...how would we live without that? They came after the telephone created -by Alexander Graham Bell. We have a faster way to communicate when we're anywhere but home. Before, if you were out somewhere you wouldn’t be able to contact people without getting to a phone booth.
2) Planes were invented by the Wright Brothers because we needed a faster way to travel from different countries separated by long distances. Before that people would have to go by ship, or could just not get to wherever they wanted.
3) And then the radio. We can listen to music in the car wherever we go. As long as we can get the signal in range...But its another form of entertainment for us.
