Home to a rich biological diversity, Brazil’s natural landscapes have been losing ground faster than researchers can study them. In an attempt to draw the public’s attention to this problem the Zoology Museum of the University of São Paulo inaugurated an exhibition in December, entitled ‘Biodiversity crisis – Nature threatened’, which is open to the public until May 17. “The difference between what is known and what still needs to be discovered is one of the most serious hindrances to the formulation of efficient measures that will help us achieve an acceptable level of sustainable development”, zoologist, Hussam Zaher, curator of the exhibition, writes on the museum’s website. From the stuffed animals, pictures of insects, which include a splendid variety of butterflies of all shapes and colors, photographs and videos, the public can get some idea of the wealth of Brazilian fauna and flora. Visiting times are from10 a.m. to 5 p.m., from Tuesday to Sunday. The museum team has also prepared a film show on environmental themes, with sessions on Saturdays and Sundays.
