The Swiss Federal Statistical Office shows that we are experiencing a constant decline in biodiversity around the world. This loss negatively affects human well-being, because biodiversity contributes to poverty reduction. It does so by enabling food security and health, providing clean air and water, and storing CO2 emissions. Biodiversity is thus the basis for ecological development (admin.ch). Villiger is committed to conserving biodiversity. One example of this is the use of bee flaps in disposal systems in which glass is collected. Glass collections attract insects and bees because of the residual liquids they attract. These die in the containers, as they enter the systems through open throw-in openings, but cannot find their way out. The bee flap, however, closes such openings, so that we can contain bee mortality.
