Overcrowded? Ridiculous. Open up Google Maps. Switch on satellite view. Scroll around the planet. It&#x27;s all empty space. Sure, we need to stop using carbon fuels. Yes, we need to stop polluting the oceans. But the earth is practically empty.<p>Switching power sources is the actual problem. And let&#x27;s choose one that&#x27;s also cheaper and more plentiful. Most of the other problems can be overcome with more and cheaper energy (like water for example).<p>But it&#x27;s ludicrous to say the earth is nearly full.
