Pollution
From the
text I read Pollution is the biggest killer in the world. This causes one in
six, or 16 percent, of all global deaths by 2015. Most of these deaths come
from diseases such as heart disease, lung cancer and stroke. Researchers say 92
percent of pollution-related deaths exist in poor countries, especially
countries with much economic development. Air pollution is the biggest killer.
The second largest killer is water pollution.
