Technology can help society in environmental protection, mapping and managing aggressive events. The plastic waste produced by society degrades the environment in several ways: difficult to decompose; attacks biotas; it pollutes oceans, seas and marine resources, in addition to spreading micro plastic, an aggressor that is difficult to identify and perceive. The objective of this research is to use information technology as an ally in the defense of Parque do Cocó in Fortaleza, Ceará, to map, register, denounce and generate strategic knowledge that helps decision-making against plastic waste discarded in the surroundings of the park. The research methodology used was applied research, when we used a real model to test possibilities for the benefit of our community. The research also has a quantitative approach to evaluate the results obtained during field collections. In the field collections, three categories of garbage were registered and georeferenced: rigid plastics; soft plastics and other types, such as cans, bottles and aluminum containers. In the collection carried out in April / 2021, we recorded 107 garbage points, an average of one plastic garbage every 23.36 meters, in the next collection, in May / 2021, 156 garbage points were recorded, an average of one garbage every 16.02 meters. In the last collection in January/2022, 331 points were registered, an average of one piece of garbage every 7.57 meters. In conclusion, we observed that the relaxation and flexibility of the quarantine imposed by Covid-19 resulted in a significant increase in plastic waste discarded around the park, consequently, more garbage in the mangroves, which flow to the Cocó River, which flows into the Atlantic Ocean. Plastic waste does not disappear, it does not disappear after being discarded, it continues in nature causing damage in its route of destruction to the biota and consequently to its aggressors, humans.
