Recovering degraded areas under the influence of urban waste

The origin of solid waste is one of the key factors in understanding the degree to which it damages the environment. In order to discuss and analyze the problem of solid waste in large urban centers, it is necessary to take a historical approach to the production of waste. In Brazil, from the 1950s onwards, with the use of packaging, waste production increased considerably. In the biosphere there are large ecosystems, whose characteristics depend on their geographical position, their geological history and the biological evolution of the planet. In order to organize an understanding of the process of recovering springs, it is necessary to take a preliminary look at the importance of water in the context of life in large natural reservoirs (oceans, lakes and rivers), since there are various living organisms there, from large fish and mammals to tiny single-celled beings, the protozoa. Among plants, large algae and microscopic algae play a vitally important role for life on earth (MAGOSSI & BONACELLA, 2013).
