Thus, terrestrial protected areas and international agreements are necessary to preserve habitat and halt biodiversity loss. The collapse of biodiversity would be one of the most serious issues that result from globalization. As remarked by Scholte(as cited in Hansen, 2010), the extinction rate has been exponentially increasing since 1995. According to Leakey & Lewin(as cited in Hansen, 2010), it is believed that unregulated trades and encouraged consumption have negative impacts on the loss of biodiversity and dramatically increased extinction rates. Moreover, biodiversity is fundamental to economic growth and approximate 40% of trades are based on biological products (Gabriel, 2007).
However, at least three out of five of the principle pressures are caused by humans, although it is arguable that we do play a crucial role in speeding climate change and transporting invasive species. Ecosystem degradation and biodiversity loss is almost like the result of the other issues. The impacts of this issue are important in many ways. Up to forty percent of the world’s economy depends on natural resources, and perpetually using these resources inevitably means that they will run out. The economy would suffer greatly.
The human population has continued to grow through the decades. The increasingly large number of people that have become apart of the world population has become a major problem. The consequences of the world being over populated has numerous effects which include: Environmental effects, depletion of natural resources, effects on the economy, food and water instability, and mass species extinction. Without a solution to the rise in human population, by the year 2020, 8 billion people will live on earth and by the year 2050, 9 billion people will inhabit the planet. ￼ Such an increase will bring about an overwhelmingly large usage of the planets resources.
