Everyones is saying we could find another planet blah blah blah. But, if we can't get close to most of the planets how are we supposed to explore them? So it's not worth it! I know everybody has the same reason problems on earth but, it's true if we can get in trillions of dollars in debt with other countries. Imagine how we could get in with ourselves. When the government says we'll buy this and this and that and spends all of it on space. So work on the planet we have and we won't need a new one! новерно
Now everyone has mobile phones. Naturally, because this allows us to be in touch with loved ones at any time. I remember when there were no mobile phones, it was difficult to find someone at home, calling on the city. And to call another city, people went to the post office and ordered negotiations. It's different now. Parents can call a child walking on the street and make sure everything is okay. You can be in touch with your old grandparents and come to their aid in time if you suddenly need them. I believe that mobile communication is an unconditional achievement of technology that serves a person in all spheres of life.
