Migration has always been a part of human life throughout history. In the past, people used to migrate from one place to another within a region or a country for the sack of better life, education, health, employment, security etc. Nowadays due to globalization, the world has been so interconnected that people frequently move from one country to another and from one continent to another. 

On the one hand, some people seek better prospects for life on the other sides of the world at the same time millions of people are forced to flee human rights violations, social, political, environmental and security issues. 

We have examples of such refugees who flee these issues, for example, Afghan refugees in Pakistan, Rohingya refugees in Bangladesh, Syrian refugees in Greece, Turkey and other countries of the region. In recent years natural disasters have also contributed a lot to the issue.

Different international human rights organizations like Amnesty International, UNHCR and civil society work to facilitate refugees but still, there is a great danger as there are risks of human trafficking and other forms of exploitation in refugee camps, sometimes they get detained by the authorities on the arrival to the new country. 

Recently a refugee camp was burnt down in Bosnia in a dispute among politicians over where to house them, leaving some refugees to spend the cold night at a damaged metal container and others walked through woods to the nearest town.

Apart from socio-political causes, environmental factors are greatly contributing to the migration and refugee crisis in the world. The disasters induced upon different regions due to Climate Change result in the displacement of people from one place to another. In winters, like many countries of the world, people in Pakistan migrate from Cold mountainous northern regions to main cities in the southern part of the country and vice versa. 

It results in the rapid increase in the population of cities in winters, results in more consumption of resources and more strain on urban infrastructure. 

On the other hand, due to the rise in the average global temperature, the main ice sheets of the countries started melting rapidly, creating floods in summers which destroy crop-lands and villages forcing people to displace them from their homes. Various parts of Pakistan faced such severe disasters over recent years.

According to experts and activists of Climate Change, this is only the beginning and worse is yet to come if we do not take appropriate steps to tackle the issue. If the global temperature is not controlled the ice on the mountains would be vanished in the coming decades forcing the communities dependent on glaciers to flee their homes, adding to the existing refugee crisis. 

The issue needs to be addressed on an urgent basis by all from the international level to the local communities level so that people know sustainable use of the resources.

In Pakistan, PTI's government has initiated the billion tree project to cater to the issue but planting trees is not enough unless other issues like deforestation, pollution, carbon emission etc. are not controlled, which contribute greatly to the issue.
