"An Innovative Way For Heating Greenhouses Using Solar Energy During The Winter For Summer Crop Production" - “Wall of water” made of black PE water tubes. "...a simple, sustainable, nonpolluting, no emissions system for growing summer crops in winter by raising the temperature using only solar energy."
Urge the EPA to ban the use of neonicotinoid pesticides from being used on crops and in household products to protect nature’s hardest workers, bees! It’s no longer a mystery. We know what’s killing the bees. They’re being poisoned by neonicotinoid insecticides, manufactured by Bayer Syngenta. Of the 100 crop species that provide 90 percent of the world's food, over 70 are pollinated by bees. No bees, no pollination! No food!. PLZ SIgn Share!
