Beans And Biodiversity In Colombia

As the world's population grows, and towns and cities expand, the natural world is under threat. Millions of species are said to have become extinct as tropical forests shrink, for example. At risk is the diversity of natural species - animal, plant and insect, that exist in the wild. It is from this stock that, for example, new strains of pest or climate resistant foods can be bred. UN in Action looks at work being done in Colombia, to preserve the genetic stock of one of the world's most important foods - beans, the poor people's beef. Bio-diversity is one of the environmental issues that will be discussed at 1992's Earth Summit in Brazil.
