Passage Three
As the climate crisis gets worse, milions of people are being displaced - forced to leave their homes - due to environmental problems. These people, often called climate migrants or climate refugees(气候难民),face serious challenges. Some people abandon their homes because of sudden disasters like floods, hurricanes, or wildfires. Others must move because of slower changes like rising sea levels, which threaten the entire islands and coastal cities, or because droughts make it hard to grow food.
One of the biggest problems for climate migrants is that they do not have legal status under international law. Current laws protect people who are fleeing their countries due to war, persecution(迫害),or violence.However,these laws do not include climate change as a reason for seeking refuge; therefore, climate migrants do not receive the same protections or access to help as refugees. Climate immigration on such a scale is quite a recent phenomenon. For this reason, many countries lack clear policies for helping people displaced by natural disasters.
In response to this growing crisis, governments and organizations are working to provide aid and support to climate migrants. Humanitarian groups like the Red Cross and the United Nations High Commissioner for Refugees (UNHCR) are providing food, shelter, and medical care to people displaced by extreme weather events.These organizations play a key role in helping people recover after disasters, but long-lasting solutions are needed as well.
Some efforts focus on adaptation, which means helping communities prepare for the effects of climate change. For example,in areas where floods are likely to happen, building better flood defenses like strategic dams and stronger river banks, can allow people to stay in their homes. In drought-affected regions,introducing new types of crops that can survive with less water may help farmers continue to grow food. However, many communities lack the resources to implement these solutions on a large scale, so international support is needed. Another form of aid is resettlement programs, which allow climate migrants to move to other countries. However, these programs are often small and do not help enough people.
