The city of Puerto Vallarta is made up of 130,067 hectares, of which 6,493 are used for agriculture, 19,700 for livestock activities, 93,408 for forestry use, 1,340 are for urban land and 9,068 hectares have other uses, and the remaining 58 hectares are not. specifies its use (Loss of Mangrove Surface in Mexico, 2005). This region has a great diversity of wildlife species, but it also has a significant amount of endemisms, species that are only found in this area. The change in land use destined mainly for urbanization, livestock and agriculture directly affects these endemic species due to the loss and modification of the different habitats where they live along with many other species. Deforestation is also one of the main causes of the loss of biodiversity in the area, due to the use of land for crops. The maintenance of the vegetation in the region is essential, for example, the forests in the high areas of the mountains that surround the city serve as collectors of rainwater which prevents flooding in the streets of the urban area., It also represents the 80% of the vegetation in western Mexico (Environmental Aspects and Risk Prevention in Puerto Vallarta).

The constant growth of the urban area, mainly due to constructions for tourist purposes and for local housing, has had a direct impact on the region's biodiversity, in addition, the different tourist activities related to nature have also modified ecosystems, and this as a consequence to the proximity of visitors to wild species can also alter and modify their behavior (Natasha Molina, 2016). Faced with this problem, the environmental authorities have implemented several conservation programs to protect and care for the natural resources and ecosystems of Puerto Vallarta, although it has not been enough so far. It is necessary to implement comprehensive projects between society, industry and government to be able to declare several Protected Natural Areas, greater planning before expanding the urban area and protecting more species.

Currently Puerto Vallarta is part of the regions that are priority for conservation in Mexico, recognized by CONABIO (The National Commission for the Knowledge and Use of Biodiversity). Fortunately, there are many specialists in environmental issues in the region interested in protecting and caring for the port's biodiversity, in addition, citizens have always been characterized by actively participating in the different awareness campaigns that are carried out in the city, as well as in activities and projects in favor of the environment. I am sure that with my participation, that of society, government and industry, we will be able to make a positive change in Puerto Vallarta and we will stop the loss of biodiversity. This alarming example, which in turn is being solved little by little, is undoubtedly part of many other cities and regions in danger and threatened by anthropogenic actions around the world, and it is a situation that must be addressed as soon as possible, to avoid irreversible consequences. The planet needs us and we must all be united with the same goal, to reverse environmental problems.
