Why might a large scale approach to conservation be more effective than a species or population level approach
What will be an ideal response?
Answer: There are a lot of areas where species are diverse. The name for these areas are called hot spots. They contain a big population and vast variety of species within their natural habitat. When we conserve, we actually end up protecting populations from extinction. The management is also a lot less complex compared to conserving a species. On the other hand, genetic diversity is high in larger populations compared to smaller ones. When genetic diversity is present in a greater capacity, there is a higher chance of species surviving in the area. In smaller populations, there is a greater chance of the population bottlenecking. This allows for a decrease in population size and genetic diversity. If there is conservation of a whole ecosystem, then we can be ensured that there is a natural equilibrium that can be held constant. The species will also continue to survive and thrive within their environment.
