The migration of species has a long and interesting history.
Migration, due to voluntary or involuntary reasons is invariably driven by the need for safety, security and survival at a basic level, primarily seen with animal migrations, and factors like growth and prosperity specifically seen with human migrations. Irrespective of the reasons for migration, the frequency and magnitude of it can completely transform landscapes, habitats and the climate.
Interestingly enough, as per a report on migration and climate change, the single biggest impact of climate change could be on human migration itself—with millions of people displaced by shoreline erosion, coastal flooding, agricultural disruption and even wars.
The problem really is one of time (the speed of change) and scale (the number of people who migrate). Cities like Mumbai are a great example of human migration, where millions of people throng the city every year in search of better prospects and livelihood.
