Air pollution rates vary widely around the world and depend on factors such as population density, industrial activity, and transportation. According to the World Health Organization, around 90% of the world's population breathes air that exceeds their guidelines for pollutants. Some regions, particularly in urban areas and developing countries, experience higher levels of air pollution than others.

According to the World Health Organization, around 7 million premature deaths are attributed to air pollution each year, globally. This includes deaths from outdoor and indoor air pollution. Additionally, pollution from water, soil, and chemical exposure can also contribute to health complications and deaths.
Water pollution is a serious problem for the entire world. It threatens the health and well being of humans, plants, and animals. As the world became more industrial and smaller due to communications and trade, accidental and purposive hazardous dumping have contributed to the problem of sea pollution. All water pollution is dangerous to the health of living organisms, but sea and river pollution can be especially detrimental to the health of humans and animals. Rivers and seas are used as primary sources of potable water by populations all over the world. Another serious consequence of this pollution is the effect of this pollution on trade in the polluted areas. This paper examines cases which reflect different causes of sea and river pollution, the seriousness of this pollution, the effect of this pollution on trade, and a possible global solution to this problem.
