Curitiba is a great example of an ecologically sustainable town. They have various programs to encourage the sustainability of the city. One of these programs is their recycling system, in which a trash truck from Curitiba goes to an individualís house and collects all of the recyclable trash produced in their households. They go from house to house encouraging people to save their trash and separate organic trash from the non-recyclable, discouraging the waste of recyclable material. When going from house to house, they pick up their trash in order to make sure that no recyclable trash is wasted. During the day time they pick up the trash of people who live in areas farther away from the center of the city. During the night-time they collect the trash of people who live in the center of the city.
Curitiba also has the Green Exchange Project. The poorest neighborhoods of Curitiba do not have roads and proper sewage. It is almost impossible for garbage trucks to go to these neighborhoods. To encourage residents not put their trash in improper places. The Green Exchange Program exchanges encourages residents to bring recyclable trash to sanitation facilities. In exchange they receive vegetables and fruits. This program has achieved goals of increasing recylcing and alleviating poverty.
In Curitiba there are areas that are unurbanized, that results in a hard passage for trash trucks to move around the city, thus making it harder for buses to come in and out of the city. Studies say that the overflow of polluted trash around small cities resulted in various diseases generated by types of mosquitos and rats and various others pests, striking especially infants. Curitiba also reviews all the bus routes to make sure they are using the most efficient route, that helps the city produce less pollution. Curitiba is a model city, and other cities should follow the example of Curitiba to become more ecologically sustainable.
