Biomes and Diversity Over the past few centuries, man has caused endless ecological devastation to Earth. This has resulted into the food chain supply being severally disrupted. The situation is becoming from bad to worse. The day is not far when basic demand of animal life (food and water) will be greater than the supply (Patterson et al 2012). In this situation, humans and animals will diminish from earth. While we humans use our intelligence to survive, our numbers will definitely reduce drastically. I think we should be concerned with the speeding rate of extinction. When we take a closer look at the number of species becoming extinct, we would realize our folly and how we are treating the environment with total disregards. We are inadvertently destroying the planet and the other animals, which are part of it. The day is not far when inevitably, we will be the next. Hopefully human will realize their error and make a conscious effort to create a change for the better. Since we share the world with several other species of plants and animals, it is our duty to consider the consequences of our actions. Since the past several years, increasing human thoughtless activity has resulted into rapid destruction of our ecological habitats all over the world. Therefore, it is vital to preserve all types of biomes since each one of them contains many unique forms of life (Sala et al 2001). However, the continued heavy exploitation of certain biomes, such as the forest, freshwater, and marine, may have more severe implications. Forests are equally important since most of diverse biotic communities in the world reside there. Within these biomes, exist a wealth of potential medicines and millions of unseen and undiscovered species. Furthermore, forest possess global climate – buffering capability, so their destruction may cause large scale changes in the global climate. Increased demand of homes, paper and other wood products have not allowed for much conservation of forests. Wiser use of the forests and efforts to re- plant trees have however helped to slow down the depletion of these damages caused by deforestation . Timber exploitation, slash and burn farming, and felling for industrial use or cattle ranching etc. are some of the major reasons for diminution of forest areas. Public attention to this exploitation has helped in alleviating this problem to some extent, even though there are many challenges to be faced by mankind. Freshwater and marine biomes are perhaps the most important of all the biomes. Water is the medium where they are found and it is also the basis of life. It supports life, and millions of species live in it or are a part of their lives. Freshwater biomes supply us with our drinking water and water for crop irrigation. The world's oceans have an even greater effect on global climate than forests do. Water has a high capacity for heat, and because the Earth is mostly covered with water, the temperature of the atmosphere is kept fairly constant and able to support life. (McKinney et al 2003) Freshwater biomes have suffered mainly from pollution. Runoff containing fertilizer and other wastes and industrial dumping enter into rivers, ponds, and lakes and tend to promote abnormally rapid algae growth. When these algae die, dead organic matter accumulates in the water. This makes the water unusable and it kills many of the organisms living in the habitat. Stricter laws have helped to slow down this thoughtless pollution. Overfishing and pollution have threatened to make oceans into ecological disaster areas. Industrial pollutants that are dumped upstream of estuaries have rendered many marine habitats unsuitable for life. Again, tighter regulations have been used to prevent further destruction of the ocean biomes. By educating people about the consequences of our actions, we can all gain a better understanding of how to preserve the Earth's natural biomes. The areas that have been destroyed the most will never regain their original forms, but conservation will help to keep them from getting worse. References Patterson B.D., Leonora P.
