Y de esto qué decís sandías?

Johan Norberg nos trae un informe sobre indicadores ambientales. Recojo lo que citó Johan Norberg:

"Air pollution fell again in the United States to its lowest level ever recorded, but hot air over the subject continued to increase. Long-range world population projections fell, for about the 20th year in a row. Bald eagles, whales, some ocean fish stocks, and U.S. forestlands all showed increases in numbers. And the latest federal study found that wetlands in the United States are at last expanding, reversing three centuries of decline."
