What is the current state of the global refugee crisis and what are the best solutions to address it?
A vast number of issues cause the global refugee crisis. But here are some possibilities and how to start fixing it.

1. Global inequality: With more prosperous nations come opportunities that draw immigrants with highly skilled workers from undeveloped countries. This movement causes a population effect called brain drain on a large enough mass exodus of skilled workers. Brain drain causes high-end businesses and governments to function correctly, and thus causes undeveloped countries to become even worse off and cause an even more significant amount of immigration.

2. Global warming: With stronger and more frequent storms, fires, and droughts. Undeveloped countries lack the deep pockets and infrastructure to deal with harsher weather. Unable to bounce back from disasters as quickly, the higher costs will run down their resources and cause countries to fail to keep up. People will look elsewhere to live without anything to tie them down.

3. Warfare: With the Wars. Villages and cities can be wiped off the face of the earth, causing people to leave as their homes no longer exist. Along with drafts and conscription can lead to mass fleeing.

Combating the refugee crisis would require primarily improving the wealth of undeveloped countries in a way that will be long-lasting, along with the infrastructure that can shorten crisis response times.
Which one of these factors is considered to be the largest contributor to the refugee crisis?
According to the UNHCR, the UN Refugee Agency, the largest contributor to the refugee crisis in 2020 was war. More than two-thirds of all refugees worldwide came from just five countries, all of which have been affected by armed conflict: Syria, Venezuela, Afghanistan, South Sudan and Myanmar. War can cause people to flee their homes due to violence, insecurity, human rights violations, persecution and fear. War can also destroy infrastructure, disrupt livelihoods, create food insecurity and exacerbate poverty. War can also trigger other factors that cause displacement, such as climate change and hunger.

Therefore, war is considered to be the biggest cause of the refugee crisis in the world. However, it is important to note that other factors, such as persecution, climate change and inequality, are also significant and interrelated causes that cannot be ignored or overlooked. The refugee crisis is a complex and multifaceted phenomenon that requires comprehensive and holistic solutions.
