Squandering Our Genetic Heritage

The Pavlovsk Experimental Station near St. Petersburg, Russia, is considered a priceless repository of agricultural biodiversity. An estimated 90 percent of its seed varieties are not found anywhere else on the planet — more than 5,000 rare varieties of fruits and berries from dozens of countries. The seeds are irreplaceable jewels of genetic history that could be vital in developing new plant varieties as climate change threatens existing varieties of plants.
