Explanation:
Due to increasing natural disasters (such as volcanic eruption) and arthropological activities (such as mining) that led to the emission of harmful gases, changes in the atmosphere and overall climatic conditions is established.
They saturate the atmosphere and due to limited carbon sinks to absorb them, they alter the climatic parameters like temperature, rainfall, and relative humidity.
The effects of change in climatic parameters are flooding, habitat destruction, increased predation, and among others. Thus, leading to dispersal of some animal species and decline of many others.
Predator-prey relationship also plays an important role in the expansion (likely through migrating from danger) and in most cases decline of some animal species, especially when there's limited prey species to go round for the predators.
