Migration is essential for species survival and adaptation from "summary" of The Next Great Migration by Sonia Shah
Migration is not just a random occurrence; it is a crucial process that ensures the survival and adaptation of species. Through migration, animals are able to escape unfavorable conditions such as harsh weather, lack of resources, or predators. By moving to new areas, they can find better opportunities for survival and reproduction. Migration also plays a key role in genetic diversity. As animals travel to different environments, they come into contact with other populations, leading to gene flow and the exchange of genetic material. This genetic mixing allows for the creation of new variations that can help species adapt to changing environments and challenges. Furthermore, migration helps species respond to environmental changes and threats. As habitats are altered or destroyed by human activities, animals need to move to new areas in order to survive. Those that are unable to adapt and migrate may face extinction. In addition, migration can have important ecological consequences. Many species rely on the movements of other animals for food, pollination, or seed dispersal. If migratory species disappear, it can disrupt entire ecosystems and lead to cascading effects on other plants and animals.- Migration is a fundamental aspect of the natural world that enables species to thrive and evolve over time. Without the ability to move and adapt to changing conditions, many species would struggle to survive in a dynamic and unpredictable environment. By embracing the power of migration, we can better understand and appreciate the complex interconnectedness of life on Earth.
