Final answer:
Short-term environmental consequences of an alien invasion can include increased pollution, changes in ecosystems, and the introduction of diseases and invasive species, leading to varied disruption in normal environmental functioning.
Step-by-step explanation:
The possible short-term environmental consequences of an alien invasion could include increased pollution and atmospheric disturbances, disruption of ecosystems and plant life, the introduction of new diseases and invasive species, and even changes in the life cycle of insects and animals due to altered seasonal patterns.
Such disruptions can lead to consequences like extinction of economically important species, increased or reduced predation on native species, and potential unseasonal rainfall events. Given these possibilities, the correct answer would be D) All of the above.
