The primary source of energy for fossil fuels are now. However, there are alternative sources of energy: wind, solar radiation, ocean waves, the energy flowing rivers.
 * Forests and other vegetations **

Plants can also be damaged by acid rain. In cultivated areas, limestone may also be added to increase the ability of the soil to keep the pH stable, but this tactic is largely unusable in the case of wilderness lands. When calcium is leached from the needles of red spruce, these trees become less cold tolerant and exhibit winter injury and even death.
 * Human health **

Scientists have suggested direct links to human health. Fine particles, a large fraction of which are formed from the same gases as acid rain (sulfur dioxide and nitrogen dioxide), have been shown to cause premature deaths and illnesses such as cancer and other diseases. For more information on the health effects of aerosols see particulate health effects. 1. Alicja, Marta, Asia, Kasia, Sandra III B  What Acid rain has done ? There are many bad things that have happened because of acid rain and here are some. In Sweden, drinking water once contained enough water to make people's hair turn green. In the Czech Republic, many trees lost all their leaves as a result of acid rain. The Taj Mahal in India, one of the ten wonders of the world, is being constantly threatened by acid rain. Some famous statues, such as the Lincoln Memorial and Michaelangelo's statue of Marcus Aurelius, have started deteriorating because of acid rain. In London in 1952, very thick acid smog killed 4,000 people. 2. Alicja, Natalia, Marcelina, Agnieszka, Marta, Octavia n Poland major part of trees is damaged and in the future they will become endangered. The main causes of the atrophy of the are trees : - damage of leaves - acid rains destroy a protectiwe layer of the wax on leaves and needles so respiratory stomata are damaged. This proccess causes an excessive water evaporation. The photosynthesis is disrupted. The trees are sensitive to climate conditions such as temperature, humidity and winds. Leaves decolorize, dry and fall in effect of this procces. Leaves become visible memorial of environmental degradation because of the impact of acid rains.

These are chemical compounds which break down into carbon, fluorine and chlorine. Then enters the chlorine reacts with ozone, leading to the formation of simple oxides and oxygen. Oxides of chlorine combine to turn the oxides of chlorine and chlorine release single atoms, molecules that break down ozone. 4. Sandra P., Sandra M. Agnieszka, Ania cid rain -is a rain or any other form of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfur dioxide into the atmosphere with positive results. However, it can also be caused naturally by the splitting of nitrogen compounds by the energy produced by lightning strikes, or the release of sulfur dioxide into the atmosphere by volcano eruptions.

// Every year, new place to deposit all kinds of illegal waste. It is especially evident on the outskirts of town, adjacent to housing estates, near the little busy roads, on the edge of forests or in zadrzewieniach midfield. As you can guess the growing number of "wild dumps" is not without negative impact on the environment, // 6 Ola P., Basia R., Asia Ł,. Kasia Sze., Patrycja K. Our planet is dying, because of our activites. We think there is a lot we can do to stop it. First of all we should stop cutting down the rainforest, which are our lungs. What’s more this forest is a source of plants, which can be used in the medicine. Moreover the acid rains are caused by the gases, which are emitted into the atmosphere so we must you public transport or bikes to limit the petrol in our country. We mustn’t forget about our water and soil. They become toxic. We are polluted our water. This activites kill fish and plants. So take care of our water. Our soil are comminment by acid rains. It poisons plants and trees. 7. Wiola,Natalia,Natalia, Monika Acid rains are very harmful to the environment. Acid rain is a result of air pollution. Acid rain, one of the most important environmental problems of all, can not be seen. The invisible gases that cause acid rain usually come from cars. 8. Olga I Nikola 00000000000000000000000
