We, humans, sacrificed nature in order to have a convenient life. It will affect your kids and your grandkids and,,, We cannot go back to the past, but we can do something to make this situation better. If each one of us makes a little change for the earth, it will be a huge impact in a good way and bad ways. It is time to choose what you do. We have the responsibility to take the problem as a global citizen. We contribute to stopping global warming by creating a clean source of renewable energy, floating solar. In this modern society, electric energy is closely related to our lives. As technology developing day by day, we are becoming difficult to live without electricity. However, we are depending more than 80% on the electric system which uses natural resources such as coal-fired power, LNG power, oil-fired power, and nuclear power in Japan. Of course, natural resources are limited. We are gobbling up the Earth’s resources. We have to change this ashamed situation for the future.
