Biodiversity refers to the assortment both within and between all plants’ species, micro-organisms, and animals as well as the ecosystems in which the variety lives. Some of the primary significance of biodiversity entails the provision of sustenance; provision of ecological services, and facilitation of the food chain (Swingland, 2001). Other importance includes a pool of medical substances to cure illnesses, and facilitation of adjustment to disturbances. The Amazon forest (in Brazil) has a diverse pool of approximately 40,000 plant species. This analogy has posed a challenge to the conservationists and ecologists pertaining to determination of the Amazonian tree species that encounters the very severe extinction threats.
Currently, there have erupted several threats to biodiversity. These risks include agriculture, urbanization, development, deforestation, infrastructure, and population increase. Amazon’s clearance for agricultural purpose amounts to the primary economic goal accruing to Brazil. However, the prevailing deforestation trends (for agriculture) have reduced carbon sequestration, besides reducing rainfall and rising temperatures. Additionally, the productivity of the underlying land is further reducing. Moreover, timber logging is further a threat to the Amazon (78% illegal). Nonetheless, 1.4 million hectares of the forest has been cleared since 1970s. The progress of the development and population increase portrays the potential of the forests extinction by the termination of the twenty-first century. Nevertheless, the giant fish and the fish species in the fresh waters (in Amazon) are under severe threat due to the commercialization of the fish trading (Junk et al., 2007). Seconding this statement, only less than 25 percent of the Amazon stream basins are under protection. The loss of biodiversity poses health hazards on the human via increasing the spread of diseases. The concept of habitat fragmentation has significantly contributed to the...
