Clean air is critical for life.� Every person on the planet breathes, on average, 12,870 liters of air each day.� Even small amounts of pollution can make that air unhealthy to breathe.� Those most vulnerable to air pollution include babies and children, who are particularly susceptible because their respiratory systems are not yet fully developed.� Other sensitive groups include the elderly and people who suffer from heart and respiratory disease.� Air pollution can affect people directly � through breathing unhealthy air � and indirectly � by damaging the environment in which they live.� Polluted air can have a series of direct and indirect effects on the environment, including impacts on vegetation and man-made materials, acidification and eutrophication of ecosystems, degradation of visibility, and important effects on climate.�
In Asia and the western Pacific regions alone, air pollution is estimated to be responsible for a million advanced deaths each year.� The World Health Organization (WHO) estimates that one billion people across the globe are exposed to outdoor air pollution that exceeds recommended health-based air quality levels.� Worldwide, air pollution causes tens of millions of respiratory and other illnesses, severely affecting quality of life, and reducing economic activity.� Although air pollution has a significant impact on all people exposed, the poor are particularly at risk, having fewer opportunities to avoid exposure to damaging pollutants.� In this way, air pollution contributes significantly to the downward cycle of poverty around the world.�
Pollutants such as particulate matter (PM) and ozone contribute to rising �background levels� (general level of air quality before adding pollution from local sources) and �atmospheric brown clouds� (haze comprised of many pollutants that can be transported far beyond their source region) in various parts of the globe.� They also contribute to what has been called the �greying� of the northern hemisphere.� They not only increase health damage to crowded urban populations, but damage the ecosystems which help underpin sustainable development.� In rural areas, significant crop damage from the pollutant ozone has been observed in Asia and throughout various parts of the world. Acidification of ecosystems from long-range transboundary air pollution remains a threat in areas with significant emissions from the burning of fossil fuels, particularly in East Asia.�

Osmoreceptors within the hypothalamus detect and increase in plasma osmolarity. This results in a decrease in ADH release from the posterior pituitary, and hence decrease in water permeability of the collecting duct.
<h3>What is osmoregulation?</h3>
Osmoregulation is that the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to take care of the homeostasis of the organism's water content; that is, it maintains the fluid balance and therefore the concentration of electrolytes to keep the body fluids from becoming too diluted or concentrated.
The tendency of water to move into one solution from another by osmosis is osmotic pressure. The upper the osmotic pressure of a solution, the more water tends to maneuver into it.
<h3>Osmoregulation through kidney :</h3>
Pressure must be exerted on the hypertonic side of a selectively permeable membrane to stop diffusion of water by osmosis from the side containing pure water. Although there could also be hourly and daily variations in osmotic balance, an animal is usually in an osmotic steady state over the long term.
Organisms in aquatic and terrestrial environments must maintain the proper concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic.

The map would best be used in a report titled The Great Lakes. The lakes are considered a very important part of the North American cultural heritage.
<h3>What are the names of the five great lakes?</h3>
From the west to the east, the names of the lakes are:
- Lake Superior
- Lake Michigan
- Lake Huron
- Lake Erie
- Lake Ontario
84% of fresh water in North America comes from these lakes. This comprises about 20% of the surface fresh water in the world. Besides drinking, they are used also used for power generation, recreation, transportation, etc.
See the link below for more facts about the 5 great lakes:
