Transcript of ACID RAIN

ACID RAIN ENVIROMENTAL PROBLEM Acid rain is very harmful to the environment because it damages everything over a period of time. It makes the living things in the environment die. Acid rain also affects the life in the water and, along with the life on land. It is almost worse in water than on land because the fish that are in the water need the clean water to breathe. Once the water becomes polluted, then the fish get sick and die. Acid rain also has an effect on trees in the forests. You will find out how it affects the forests later in the presentation. - A major way acid rain affects us is our health. Everything that we eat, drink and breathe has at one time come in contact with acid deposits. This could threaten our health by making us become sick. FACT! Did you know that in Canada and the U.S, acid rain causes: 550 premature deaths, 1, 520 emergency room visits and 210,070 asthma symptom days? Don’t think that acid rain can only damage living things, non-living things such as buildings and statues can also be damaged by acid rain. It decays building materials and paints, but the worst part is it can damage non-replaceable buildings, statues, and sculptures that are part of our nation’s memories that we want to last for a very long time. When and where did it occur? Is it still a problem? As mentioned before, acid rain has been destroying the forests in Germany. You may ask how does it affect the trees in the forests? Well, scientists are saying that the acid rain damages the waxy outer coating that protects the leaves, allowing it to seep into the tree. Instead of water changing from liquid to a gas inside the leaves, gas is taking the place of the water. This prevents the plant from taking in carbon dioxide to perform photosynthesis, and the plant will eventually die. Acid rain also damages the forests in Germany by damaging the surface of the leaves and needles. By damaging the surface of the leaves and needles of the tree, it makes it harder for the trees to withstand the cold and causes the tree to die. Acid rain also harms the soil that the trees are growing in by taking most of the valuable nutrients away from the soil. It also leaves a lot of aluminum in the soil, which is harmful to the trees that grow there. What causes your environmental problem? Acid rain is caused by a chemical reaction that begins when compounds such as sulfur dioxide and nitrogen oxides are released into the air. They can rise very high into the atmosphere, where they then mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Nitrogen oxides dissolve easily in water and can be carried far by wind. The two compounds can travel long distances where they become part of precipitation that we experience on certain days. Us humans are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from vehicles release nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

In addition, the exhaust from vehicles release nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain. What specific damage was done to the environment? Human health: Air pollution like sulfur dioxide and nitrogen oxides can cause breathing diseases or can make the diseases worse. Breathing problems such as asthma or chronic bronchitis make it harder for humans to breathe. Forest Harm: Acid rain can harm forests very much. Acid rain that sinks into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil which makes it harder for trees to absorb water. With all the acids in the forests it makes it easier for infections, insects and weather changes to damage trees and forests. Lakes and Streams: Lakes and streams have a certain amount of pH and acid rains causes it to decrease. Aluminum and other elements can be washed into our soils which then wash into our lakes and streams, therefore that causes more acidity which is harmful to wildlife. Building and Object: Surprisingly acid rain can damage building and statues. The chemicals in acid rain can cause paint to chip, or even make statues look worn down and broken. What was done to rectify/fix the situation? Is it on going? Many things are being done to reduce the situation of acid rain. One big thing is to stop pollution, by reducing sulfur dioxide released from coal-burning power plants. Also by using more reusable energy such as solar energy and wind power. A big way of polluting air and causing acid rain is cars in our world. We’re trying to make newer and greener/cleaner cars to help stop polluting our air. What was the recovery time for the environment? (did the secession begin?) Recovery is still occurring. We’re not really able stop acid rain until there is no more pollution. Pollution is made every day, and the only thing we can do is reduce it. With reducing pollution we can slowly decrease the effects and acidity of acid rain. Was there any public reaction or outcomes (such as permanent changes in how we behave?) There was many public reaction to acid rain in the past years which catch the public's attention. For example the acidic sulfur in Britain's water. Most of the public's reaction was to stop polluting the air. The public has many ways to reduce population such as, using eco friendly cars and using renewable energy. **REFERENCES**
