NASA PRODUCTION PRESENTED BY BILL KEEFER, WHAT IS GLOBAL WARMING. <br /> <br />In the near future Domed Cities, are in store for us all. Those futuristic Sci fi movies to come true due to global warming, chemtrails, drought and floods. <br /> <br />Forward thinking, Plantagon will show how to grow more food in less space in its first urban HYDROPONIC greenhouse. The plan is to grow vegetables in a turning helix with minimal water, energy and the need for fertilizer. <br /> <br /> With the world's population to top 15 billion by 2050 -- and with 80% of those people projected to live in cities -- finding innovative, cost effective, and environmentally friendly ways to supply food to cities is a major challenge. <br /> <br />Because of a rapid warming trend over the past 30 years, the Earth is now reaching and passing through the warmest levels seen in the last 12,000 years. <br /> <br />Aerosols can occur in nature, but they can also originate from human activity. These animations provide an introduction to four of the varied sources of atmospheric aerosols: cities, forest fires, the ocean, and deserts <br /> <br />I am Bill Keefer, roguevalleychemtrail channel on Youtube.
