Global migration is a situation in which people go to live in foreign countries. Some people move in search of work or economic opportunity, to join family or to study. Others move to escape conflict, persecution or large-scale human rights violations. So the reason of this act is basically to protect their human rights.
Migration can bring many positive effects to both the individuals and the societies they move to. When people move to safer and more developed countries they often find better education, healthcare and job opportunities. This can lead to a better quality of life for them and their families. For the host country migrants can help fill the gaps especially in areas where there are not enough local workers. They can also bring new skills, cultures and ideas which make societies more sophisticated.
However, there are some problems come with migration. Sometimes when too many people move to a new country it can be hard for that country to give everyone enough housing, schools or healthcare. This can cause problems between migrants and local people. Some locals might think that migrants are changing their way of life or taking their jobs. If this is not handled carefully it can cause unfair treatment or even fights.
Also, when many people leave their home country it can lose important workers. For example, doctors, engineers and other smart people may move to richer countries. This can make it harder for their home country to grow and improve.
In conclusion, global migration is often needed so that people can live safely and freely. It has many good sides but it needs a good planning. If countries create fair rules and help migrants become part of the society and migration can make the world a better place.
