Extensive network of parks
The extensive network of parks increase the value of surrounding land. As there are parks all around the city, that's very good for the environmental sustainability as it allows rivers to flow free. There are 16 parks, 14 forests and more than 1000 green public spaces. As a whole, the green urban areas in Curitiba are among the largest in the world and every inhabitant of the city has approximately 52 m² of nature. The city's Municipal Secretariat of the Environment produces 150,000 endemic cuttings, 16,000 fruit trees and 260,000 flower seeds, at the same time as 350,000 cuttings are nursed in a botanical garden and three greenhouses. As they use sheep to cut the grass in these parks, that also helps both the environmental and economical sustainability as then men don't have to be paid and the machines don't pollute.
