The effects of acid rain on our environment and ecosystem

Check out some of the appalling photos of water pollution shared by our readers. Clean water is very precious — there are about 1 billion or more people who do not have excess to proper drinking water.

The effects of acid rain on our environment and ecosystem

Total terrestrial CO2 in billion tons 2, to 2, Slow removal of CO2 from the atmosphere is done by the oceans, through biological and chemical processes which take decades, if not centuries, to complete.

CO2, methane and CFC have varying interactions. CO2 can cool the atmosphere, slowing the photoreaction causing ozone destruction. At the same time, however, the cooling causes high altitude clouds to interact with the CFC, destroying the ozone.

Methane, which can be produced or destroyed in the troposphere depending upon what other chemicals are presentalso affects the chemicals that produce ozone at the earth's surface. Getting From Here To There The lyrics of a song popular in the 's called the ocean a desert with "the perfect disguise above.

While containing water in the form of H20 molecules, the air moves in eddies and currents, swirling horizontally and vertically around the planet. Like the ocean, the air circles the hemispheres with its cargo of molecular particulates, aerosolized chemicals, clashing atoms, dancing gases, ions grasping at polarities, all transformed by the sun's energy, all going on above our heads and all around us day by day, sight almost unseen.

As the day progresses, the air drifts higher and eastward, skimming the deserts of Nevada and Arizona, often reducing the visibility over the Grand Canyon, jazzed up with a bit of plutonium from Colorado.

When the winds and temperature and water content mixtures are just right, the haze may extend as far as Utah before heading over the Rockies.

Here the currents circle, some continuing east, others heading south Brown,p. As the high currents head over the great plains, they pick up bits of detritus from the f arms and factories, smoke from wood stoves and power companies while heading north and east. Here they meet and mingle with currents from the south, perfumed with the rising plumes of waste from paper mills and chemicals manufacturing.

Continuing ever eastward, from the Bread Basket to the rusted Iron Belt, the currents eddy and separate, heading to New England and the Florida keys, there to be met by the Atlantic off-shore currents, mingling and migrating ever eastward.

Throughout all this traveling and commingling of air and space, the molecules diffuse and collide, break apart and join, moving up through the troposphere to the stratosphere. Or falling to earth. Acid Rain Acid rain is more properly called acid precipitation or wet deposition: Dry deposition, which some scientists believe to be equal in volume to wet deposition at least over the North American continentis carried aloft by the winds and air currents, falling without moisture as a medium of transport Miller and Miller, In the west as in the east, lakes and streams are the first to show the affects of acid deposition.

In Colorado, lake failure was initially thought to be caused by depositions from Denver. It has now been shown to be from coalfired power plants elsewhere in Colorado as well as from surrounding states Millerp. A study of 64 lakes in the Olympic and Cascade Mountains in Washington all show low pH, resulting in declines in fish populations.

Declines in forest populations are now being seen in the Sierra Nevada range in California, especially in the high elevations consistent with the effects of acid precipitation in other high altitude forested areas Miller and Miller,p. In the east the primary damage is in the Appalachians and Great Smokey Mountains.

The worst damage, however, is considered to be in the Adirondacks These high altitude forests in New York, Vermont and New Hampshire have suffered extensive destruction. In studies conducted fromseedling production and tree density fell by one-half.

Not far behind is North Carolina's Mount Mitchell, now covered with dead and dying trees Lean,p. As with Camel's Hump and Mount Mitchell, scientists have linked the death of the Ponderosa and Jeffrey pine trees in the San Bernardino Mountains east of Los Angeles with that city's nitrous oxide reacting with its hydrocarbons.

Research in Europe and the U. Samples from thousands of trees show that annual growth rings have become smaller since Leanp. The greatest losses in these forests have been on the slopes facing the prevailing winds Miller and Miller,p. In evergreens, the first sign of pollution damage is the yellowing and early dropping of the needles, followed closely by the deformation of the shoots, root deterioration, thinning of the crown and, finally, death.

Other trees try to conserve energy by shedding leaves. Still others try frantically to reproduce, putting out masses of sterile cones and seeds. In many places, the vegetation in the understory and the ground itself is diseased, dead.This lesson will introduce you to acid rain.

You will learn what acid rain is, what causes it, and how it damages the environment. You will also learn about the simple things people can do to. Our Common Future: From One Earth to One World - A/42/ Annex, Overview - an element of the body of UN Documents for earth stewardship and international decades for a culture of peace and non-violence for the children of the world.

What is Air Pollution? Pollution is now a common place term, that our ears are attuned to. We hear about the various forms of pollution and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. 7.

Dimension 3 DISCIPLINARY CORE IDEAS—EARTH AND SPACE SCIENCES. E arth and space sciences (ESS) investigate processes that operate on Earth and also address its place in the solar system and the galaxy. Thus ESS involve phenomena that range in scale from the unimaginably large to the invisibly small.

An overview of acid rain and its history, causes, and effects as well as solutions to this environmental problem. CO2 is plant food Earth's current atmospheric CO2 concentration is almost parts per million (ppm). Adding another ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants.
