Air pollution comes from a wide variety of sources * Vehicle or manufacturing exhaust * Forest fires, volcanic eruption, dry soil erosion * Building construction or demolition Many scientists believe that global warming is also related to increased air pollution. 2. Water Pollution Water pollution involves any contaminated water, whether from chemical, particulate or bacterial matter that degrades the water’s quality and purity. It can occur in oceans, rivers, lakes and underground reservoirs. Causes of water pollution include: * Increased sediment from soil erosion * Improper waste disposal and littering * Leaching of soil pollution into water supplies The effects of water pollution include decreasing the quantity of drinkable water available, lowering water supplies for crop irrigation and impacting fish and wildlife that require water of certain purity for survival.
Because they are hazardous. As in documentary they showed in an ad that fracking is safe. But what they mean by safe? If water, air and noise pollution are created by fracking then how it is safe! Fracking also created huge natural losses such as it crates pollution, destruction of forests to create its pipe lines.
(As you can guess, different fuels begin burning at different temperatures.) Heat or ignition sources lift fuel (combustible material) to its activation energy to start the fire. The fire generates heat which sustains the chemical reaction; the blaze continues and spreads. Some firefighting tactics shield the fuel from air (oxygen) to extinguish the blaze. Carbon dioxide fire extinguishers expel a cold fog of CO2 that cuts a fire off from its air supply.
Acid rain as a result of industrialization has had many negative effects on the New England region in particular. The Adirondack Mountains are of special interest due to their soil composition that does not allow for the seizure of the two primary particles in acid rain. This has caused issues pertaining to the water reservoirs in the area that now are sometimes unable to support life do to the high acidity. Acid deposition as it is more formally called is typically composed of sulfur dioxide and nitrogen oxide. These two components are naturally occurring from sources like volcanoes but the industrial revolution has exponentially increased the amount of these chemicals in the air.
These pollutants are released in the air we breathe. They are very harmful for our health. The burning of various fuels in factories and power plants emit some poisonous gases that are left off in the atmosphere. Yet without burning fuel, the production of goods in industries is not
This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals. It also affects the food sources of herbivores and insects. How does acid rain affect the environment? Acid rain has a hand in global warming as well which is rapidly changing climates around the world. With the climate changes many plants and animals are having to relocate or are dying because they are not fit for the changes in their surroundings.
Point pollution is pollution coming from one place, such as a sewage treatment plant or a factory. An example of a non point pollution source is debris from trash in urban places. An example of a point pollution source is an oil spill. Nutrients leaking into the water cause what is called over-nutrification. Nutrients such as phosphorus and nitrogen are put out into our environment, and finding themselves at the lowest point nearby, which is usually a lake or a river, or any body of water.
When acid rain falls, it sometimes raises the levels of acids in certain soils, removing nutrients from the soil that helps plants grow. Because the nutrients are removed from the soil, it makes it hard for plants and trees to resist diseases, insect infestation and bad weather. Acid rain also raises the acidity of steams, rivers, and lakes, which can harm and sometimes kill life in the water. The acids in acid rain also react with the CaCO3 in marble and limestone, which can cause damage to statues and buildings. Lakes with limestone beds are less affected by acid rain because the limestone reacts with the acids in acid rain.
Water Pollution Part 1 1. Water can be polluted in many ways, two of which are: Industrial factories and the other being indirect pollution. Industrial pollutants can come from chemical spills and just plain dumping waste into a nearby river. Also thermal waste is another growing problem, factories use the water to cool there equipment and then drain it back into the river several degrees warmer. Indirect pollutants can be a lot of things, my main point is automobiles.
China has one f the highest pollution rates. This pollution from factories is put into the water, thus contaminating it. Once the water is contaminated, it can no longer be used. If there is less use-able water available it causes droughts and water shortages. This is a human factor which can easily be stopped.
