What will be in the future with us? Solar energy, food for tomorrow, electricity,to much carbage, ...this Ecopolis program. Do you know something about this? Are few solutions to make our life better, more healthy and more clear..with simple solutions. I remember few... 1. To grow vegetables in big city on the floor, no ground,just water and air 2. to make agriculture more productive with garbage help...after this garbage is used for ground..is so simple and is good for our garden too, 3. solar energy , who can help atmosphere to be more clear, and for us is so cheap electricity....
