The only possible way we can think is using our efforts on preserving our mother nature. Electronic cars show how we can go around without polluting air. =Electronic cars show how we can go around without polluting the air.Solar power show we can generate energy without depending on fossil fuel.=Solar power shows we can generate energy without depending on fossil fuel. All we need to do is concentrating on improving efficiency.
