Water pollution is a problem that has affected the world for a long time. It essentially entails contamination of the water bodies such as lakes, oceans, rivers and ground water just to mention but a few.
Although some people may fail to understand the long-term effects of pollution, its short-term effects are easy to discern (Newton, 2008, p.102). Such effects include diseases or death of both human beings and animals. Despite this fact, human beings still pollute the water bodies, oblivious of the dangers that they are exposing themselves and animals to.
One of the main reasons for this is the fact that some of the effects of pollution may take very long before they exhibit themselves. Aquatic life has been adversely affected by water pollution to the extent of extinction of some species. Chemical pollution of water is one of the leading causes of death of aquatic life. It normally makes water acidic, and also makes it toxic. The animals that do not die are left living in very harsh conditions (Hogan, 2010, p.1).
Animals that consume these toxins may, in turn, be harvested for human consumption leading to diseases in human beings. Additionally, if water is polluted with chemicals, the amount of water available for human consumption reduces, and thus humans experience difficulties accessing safe drinking water.
The water will also evaporate and make humans and animals inhale the chemical substances dissolved in it. This evaporation will also result in acidic rain which has the same effects as water pollution. It is thus evident that chemical pollution of water not only has negative effects on health, but it also substantially reduces the amount of water available for consumption by animals and human beings.
There are a number of ways through which an individual could pollute water bodies. Some of these include; factory wastes, blood from slaughter houses, farm water with pesticides or herbicides, and all types of wastes disposed of to the water bodies. The aforementioned ways of polluting the water, makes it unable to sustain aquatic life as well as unfit for human consumption. It is therefore advisable that human beings avoid any actions or processes that could pollute water in order to live in a clean and safe environment.
Wind energy is a form of renewable energy just like solar energy. The production of energy by the use of wind power is accomplished by the use of wind turbines. The blades of the turbines are meant to rotate by the wind thus causing electrical energy which serves as a power source (Richardson, 2006, p.2). It has been used as an alternative source of energy to substitute other energy sources such as fossils.
There are numerous advantages of using wind energy, which include;
- It has negligible environmental effects. When compared to other sources of energy such as fossils which when burnt to generate electricity pollute the environment wind energy has no emissions hence safe to the environment (Perez, 2010, p.1).
- It is readily available as wind keeps blowing and is free thus making it cheap.
- The turbines occupy less space making it cheap since the size of land required is less compared to that required for hydropower.
- It is an easy way of generating electricity as no advanced technologies are required.
The main disadvantage of wind energy is that the amount of energy it generates is limited compared to other energy sources. The turbines must be located in strategic places in order for them to generate significant amounts of energy. Last but not least, Wind energy is more appropriate in areas with a lot of wind, for instance in the rural areas.
