The negative impacts of emigration on the country of origin would typically include "brain drain." This refers to the loss of skilled and educated individuals who leave their home country for better opportunities elsewhere, which can hinder the country's development and reduce its human capital.
The other options listed:
- "increased GDP" and "remittances" are often seen as positive impacts because remittances can provide financial support to families and communities in the country of origin, while increased GDP is a measure of economic growth.
- "population increase" is not a direct impact of emigration but rather a result of immigration or natural population growth.
Therefore, the best answer that highlights a negative impact of emigration is brain drain.
