The Impacts Of The El Nino Environmental Sciences Essay

The Impacts Of The El Nino Environmental Sciences EssayBiodiversity refers to the sum of all lifetime and its habitat. Biodiversity is the variety of life and the ecological systems which individuals are actively participating in. Biodiversity is important for asseverateing ecological counterweight in nature. Some benefits of biodiversity admit gentleman benefits, food, industrial and commercial products, medicines etcetera Biodiversity hotspot refers to a bio-geographic region that is both a significant rootage of biodiversity and is threatened with ravaging. Philippines, bingle of the worlds richest biodiversity in the world but also one of the most endangered areas in the world. The country contains many a(prenominal) endemic species. 6000 plants and animals anticipate in afforests that occupy barely 7% of the original hotspot. Today, the forests are tabooside for farming and development plans for the countrys growing population. The major issue is the decline of biod iversity hot sight in the Philippines1. By examining the environmental preserves, human impacts, political impacts and the saving strategies adopted to maintain biodiversity hotspots in the Philippines, this research paper will aim to develop sensory faculty and understanding of how the decline of biodiversity hotspots may be resolved.Human ImpactsPhilippines population of 80 million people survive using the countrys natural resources. With a steep population growth rate, the demand for timber has increased. Logging activities deem declined callable(p) to the deterioration of the forests however, illegal logging activities are still present. Other threats to the countrys forests embarrass mining and land conversion. In 1997, the mining industry occupied to a greater extent than half of the remaining forests. Roads, take, power, energy, ports and harbours are current issues to be addressed.2There have been negative impacts upon introducing the following exotic species to Philippines fish such as the ogre catfish and black bass toads and toad frogs including the marine toad, the American bullfrog and leopard frog and aquatic plants like the water supply hyacinth and water fern. The presence of exotic species becomes a threat to native biodiversity predator-prey interactions are more competitive, breathing out of species rightfulness through inter-breeding with exotic species, the spread of disease pathogens along with introduced species and habitat waiver for native species.3Only 10% of the sewerage in the Philippines is treated in an environmentally friendly manner. With the population rising, there are problems associated with waste circumspection and treatment. The improper waste management affects the countrys ground water, rivers, lakes and edgeal areas where the species habitats are threatened.4 all over fishing occurs when the fish are caught faster than they could reproduce. Overfishing increases the vulner efficacy of ocean ecosyste ms and may contribute to the loss of species in the region. The main issue in the Philippines involves cyanide fishing where fishermen squirt cyanide into precious chromatic holes and crevices, where reef fish prove shelter5. Other causes of over fishing include catching gr give fish too early and in large numbers so the reproduction is impaired. Economic overfishing also occurs when increase in the fish political campaign lead to profit levels that are below the desired consumption.Environmental ImpactsThe impact of El Nio affects Philippines biodiversity hotspots. The countrys weather officials define El Nio as a meteorological event that develops in the Pacific Ocean and associated with extreme rains, winds, droughts, etc6. In the Philippines, El Nio has been seen as drought events. El Nio is also the sudden prink of oceanic temperature and evaporation of surface water therefore having an effect on red coral growth and sea life. Algae living inside the tissues of coral hel p their feeding mechanism and other processes for survival. The distress to the sudden diverge of temperature causes the coral to bleach. Fish no longer live inside the coral because the coral is uneatable. The drought creates dry conditions for fish ponds. The drought also creates a negative impact on marine biodiversity by shorter fish production, curb fish growth and increase fish mortality due to stress, ridiculous water quality and disease.Philippines primary forests are being destroyed due to logging and agricultural expansion therefore, decreasing the countrys natural resources. Two incident species of animals are fitting extinct the tamaraw (the wild buffalo) and the Philippines eagle because their habitats are becoming damaged. Deforestation in the Philippines occurs because of agricultural expansion and illegal logging7. Forests extend cooling insulation to the climate but with deforestation, the climate shifts from drought into flood. The tamaraw (wild buffalo) esca pes into the forest to find limited trees to cling onto. Deforestation causes species to be displaced from their original habitats and loss of top soil causing erosions affecting the habitat for endemic species. face back at the farming industrys use of pesticides, erosions may carry the pesticides into the rivers and streams. The water is now contaminated with pesticides affecting the endemic species which live in this habitat.The destruction of costal mangroves is also caused by deforestation. Mangroves are needed to protect the coast from hurricanes and other severe weather impacts. Cutting mangroves for fuel wood limits and degrades coral reproduction. Any endemic species living under the water are bear on by losing their habitat causing a negative impact on biodiversity hotspots.Political ImpactsInadequate institutional control and poor law enforcement in the Philippines have impacted the biodiversity hotspot for endemic species. The Fisheries Code was passed in 1998 and now serves as the primary legislation for fisheries and coastal management and protection in the Philippines. The Fisheries Code fails to recognize who may access and control municipal irrigate for fishing activities. The Fisheries Code is a weak enforcement system which encourages poaching and entrancement of marine protected area boundaries. Other problems include current dimension rights, and local power relations to enable local public officials who own or have indirect business with the fishing industry may influence local policy and enforcement outcomes for their personal gain. Political influence enables many to obtain profitable forest profits, enhancing their political power and strengthening their ability to corrupt government officials. This class dominates the farmers and social economic policies with the results of legal injurying the biodiversity hot spots for endemic species. The legislated operational guidelines are often under addressed on the issues that threat en vironmental events such as lost of biodiversity. The Forestry law of PD705 is out dated because the law does not contain new methods and approaches like biodiversity protection.8preservation PlansThe World Wildlife Fund (WWF) has been working as an international organization in the Philippines since 1997. The organizations mission in the country involves preserving endemic species and biodiversity, maintaining sustainability of natural resources and reducing waste and pollutants in the environment. The organization places strong emphasis on marine biodiversity. WWF-Philippines deep-rooted their plans in 11 provinces and at minimum 28 towns.9To ensure that the cyberspace of protected regions is effectively conserving biodiversity by the conservation of Key Biodiversity Areas (KBAs) where endemic or threatened species are held in restricted areas. In the Philippines hotspot, preservation International-Philippines created a partnership with the Field Museum in Chicago, Haribon Founda tion and other local partners to rank and distinguish KBAs throughout the Philippines. With protected regions, there is also a need for field research in order to support conservation activities. indigenous species continue to be discovered and KBAs are needed to create a plan for their survival.10In the long term, landscape and sea conservation is infallible to protect the biodiversity hotspots in the Philippines. The Philippine Eagle Alliance has collaborated with other conservation organizations in order to protect the endemic species of the country.ConclusionIn young years, there has been a decline in biodiversity hotspots, particularly in the Philippines. Firstly, human impacts upon endemic species include deforestation, illegal logging, introducing new exotic species, poor sewage management and over fishing. Secondly, environmental impacts such as El Nio, soil erosion, pesticides and destruction of coastal mangroves all affect biodiversity hotspots. Lastly, political impac ts include inadequate law enforcement especially for the fisheries and coastal management, and forestation guidelines are not important in the protection of biodiversity hotspots in the Philippines. The impacts develop awareness of the collaboration efforts from WWF, Conservation International-Philippines, the Philippine Eagle Alliance and other conservation organizations which minimize the harm to biodiversity hotspots in the Philippines.
