These days, i often thought ‘where is my my house in the future?’ Then, today environmental disease have been increased too fast. For example, global warming, desertification. so earth is destroyed by environmental disease. but science will be develope. until i turned 17, i never thought that take picture using the cellularphone. science developement is no limit. so we will have set up second earth on a planet. but some people speak what we will live on a planet is too unreasonable. nevertheless environmental disease have been started already.
