These problems cannot be ignored or it might have catastrophic results on our environment. Acid rain is a wide spread term used to describe all forms of acid precipitation, rain snow and dust. Acid rain is a serious problem with disastrous effects and this problem is increasing each day. It causes grave damage to our natural wild and aquatic life and can also have an adverse effect on human life. It causes fish and plants to die in waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. However acid rain on its own is not the biggest problem. ...read more.

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is the key to their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fish's gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissue, salt such as the calcium (Ca+2. This can result in poor reproduction. The fish's eggs produced would be damaged, they could either be too brittle or too weak. The decreased Ca+2 levels also result in weak spines and deformities. Acid Rain has a detrimental effect when it come to the life of fish, although when nitrogen-containing fertilizers are washed off into the lakes, the nitrogen stimulates the growth of algae, which logically would indicate an increase in oxygen production, thus benefiting the fish. However, because of the increase in deaths in the fish population due to acid rain, the decomposition process uses up a lot of the oxygen, which leaves less for the surviving fish to take in. (Elliot .1984: 156) 4.2 soil Other issues impacted by acid rain are forests and soil. When acid rain falls onto the earth's surface it causes a large amount of damage. ...read more.

Conclusion

There are also alternative energies available to power automobiles, including natural gas powered vehicles, battery-powered cars, fuel cells, and combinations of alternative and powered gasoline vechiles. All sources of energy have environmental costs as well as benefits. Some types of energy are more expensive to produce than others, which means that not all people can afford all types of energy. Nuclear power, hydropower, and coal are the cheapest forms today, but changes in technologies and environmental regulations may shift that in the future. All of these factors must be weighed when deciding which energy source to use today and which to invest in for tomorrow In summary Acid rain is a huge environmental concern. It causes damages to our lakes, our rivers, our wild life and most importantly human life. Acid rain is absorbed in fruits, and in the tissues of animals. Although these toxic metals do not directly affect the animals, they have serious affects on humans when they are being consumed. . It also causes other problems, such as the release of aluminium and lead into our water supplies causing suffering to human life. Acid rain is a real threat for human beings and the environment. In many countries they have set different procedures to prevent acid rain and even as individuals it's still possible to fight acid rain. The amount of pollution released must be reduced. However it will take time; even if the pollution were to be stopped today the problem would not end for years to come because of the build up in the soil. ...read more.

  2. Investigating the effects of varying pH levels on the germination of cress seeds

    RESULTS After evaluating the results of the pilot experiment, I decided to make certain modifications to the experiment: * I would alter the volumes used when diluting the acid so that there would be a more diverse range of pH values amongst the solutions.

  1. What effect does Acid rain have on germination?

    INDEPENDENT VARIABLE I will mix acid with water to from the different concentrations. I will do this using a syringe. This will accurately measure the volume of the acid and water and will easily put the acid and water in the Petri dish.

    Hydrogen is also an energy carrier meaning that it can deliver energy in a usable form to consumers. Since hydrogen is an energy carrier, this means that the economy can always create new technological devices by using hydrogen as their main source.

    Carbon dioxide (CO2) reacts with water to form carbonic acid (HCO3-). Chlorine (CI2) reacts with water to form Hydrochloric acid (CI-). Some other gases that are being released in the air are carbon dioxide, carbon monoxides, chlorofluorocarbons, hazardous air pollutants, lead, nitrogen oxides, ozone, particulate matter, sulfur dioxides, and volatile organic compounds.

    Many of Britain's freshwater fish are threatened, there have been reports of deformed fish being hatched. This leads to fish-eating birds and animals being affected also. Is acid rain responsible for all this? Scientists have been doing a lot of research into how acid rain affects the environment.

    However this will happen if the seed is in any solution, and is just a result of the seed absorbing water. Therefore it will happen whether germination does or does not take place. However the emergence of the radicle shows that the food stores in the seed have been mobilised and that the seed germination is truly underway.
