The diversity of life on Earth is astounding and the full extent of its interconnectedness is beyond knowing. So arguably, it is the loss of biodiversity that is the most important factor that branches from the introduction of an invasive species, as the loss of one or more species and the redistributing resources can drastically alter the equilibrium of the environment. However, despite the fact that the surface area of designated protected areas has steadily increased since 1970, the rate of biodiversity loss … South America and Africa are most affected; in some cases, advanced stages of land degradation there are leading to desertification in dryland areas, particularly in the grasslands and rangelands. Additionally, deforestation fragments the existing forest habitats making it difficult for larger species to hunt over large territories.
