Answer:
Megacities have an impact on public health, like contamination of water. Overpopulated places can bring diseases and a lack of health protection.

C. climate change can be a concern for environmentalists
Answer:
The release of pyroclastic materials, smokes, blocks, and ashes affected the atmosphere by increasing the number of clouds and fog formation and also the earth had undergone a cooling period for a couple of year.
Explanation:
The volcano of Mt. Pinatubo was erupted in the year 1991, releasing a large number of volcanic materials, such as ashes, pyroclastic materials, and smokes, where the plume of this volcano had risen so high that it penetrated into the layer of the stratosphere.
The ashes and smoke released in this eruption got mixed up with the air in the atmosphere, causing significant air pollution. It also led to the occurrence of extensive clouds and an increasing amount of fog.
These aerosol particles were eventually distributed on earth as the stratospheric wind forced it to spread in all directions. This had a global cooling effect as the presence of aerosol particles in the atmosphere can help in reducing the amount of incoming solar radiation. Thus, the earth's global temperature relatively decreased and experienced a cooling period of almost two years.
