Thank you for your question.
I should point out that migratory species are influenced by factors all over the planet. Take the example of snow geese. These birds are affected by both developments in the Arctic and changes in farming practices in the south, for instance.
At the international level, we're seeing an increase in a number of snow goose, duck and goose populations as a result of changes in farming practices. This has considerably increased the density of snow goose populations in the Arctic. These higher densities of snow geese in the Arctic affect the Arctic ecosystems. For example, this can lead to negative effects on plant communities, transform plant communities and adversely affect other species currently in decline, such as birds—
