These non-native species can outcompete native species for resources, leading to a decrease in biodiversity. This can impact natural selection by favoring species that are able to adapt to the presence of non-natives. 4. What is the difference between a.. Overexploitation: Human activities, such as overfishing and overhunting, can lead to the depletion of natural resources. This can disrupt the balance of ecosystems and impact the reproductive success of species. Overexploitation can also lead to the loss of genetic diversity within populations, making them more susceptible to diseases and environmental changes. 5. What is the difference between a'smart' and a'smart'? Climate Change: Human-induced climate change is a major threat to sustainability, evolution, and natural selection. Rising temperatures, changing precipitation patterns, and extreme weather events can alter habitats and disrupt ecological interactions. Species may need to migrate or adapt to new conditions, and those that are unable to do so may face
