How to distinguish environmental refugees from environmental migrants?

1. Environmental refugees are called "environmental refugees" because of the migration of indigenous people in residential areas due to climate deterioration, ecological imbalance, geological variation and environmental pollution. After losing their original living environment, their life is even more difficult. According to the report of the British Tears Foundation, there are currently 25 million environmental refugees, and it is estimated that there will be 200 million environmental refugees in the next 50 years.

2. Environmental migration refers to population migration caused by the deterioration of the natural environment on which people depend. The reasons include natural disasters, ecological environment degradation, environmental pollution and other environmental factors. Environmental migrants caused by catastrophic environmental events such as floods, droughts, mudslides, landslides and earthquakes are called "environmental disaster migrants"; Environmental migration caused by desertification, desertification, soil erosion and other ecological environment degradation can be called "ecological migration"; Environmental migrants caused by environmental pollution incidents can be called "environmental pollution migrants".
