本篇assignment代写-水葫芦的防治措施讲了大量的水葫芦会限制氧气从空气中转移到水中,或者减少其他藻类和植物产生的氧气。当植物死亡和下沉时,分解的生物量导致整个水体的主要氧气消耗。由于鱼类对这些变化很敏感,它们体内的溶解氧含量最终会达到高风险的低种群水平。再往前,低水平的溶解氧最终会催化沉积物中磷的释放,从而加速富营养化。这可能进一步导致随后增加藻华或水葫芦。大量水葫芦植被的腐烂和死亡最终导致饮用水的数量和质量恶化,同时增加了饮用水处理的成本(Kaufman and Kaufman, 2013)。除了产品的国际运动之外,人类对野生动物的影响也是全球化的一个巨大结果。在现代环境中对特定种类的引入确实有一定数量的结果,太过侵入性的结果。有些物种也可能对后一种普通环境给予极好的惩罚,但部分会造成经济危害、环境危害并对人类健康产生影响。本篇assignment代写文章由美国第一论文 Assignment First辅导网整理,供大家参考阅读。

Large mats of water hyacinth restrict the transfer of oxygen to water from air, or decrease the production of oxygen by other algae and plants. When plant dies and sinks, the decomposed biomass results in the major depletion of oxygen across the water body. The levels of dissolved oxygen can end up reaching highly risky low population for fish having sensitivity towards these changes. Further ahead, low conditions of dissolved oxygen end up catalyzing the released phosphorus out of the sediments which further results in accelerating eutrophication. This can further result in subsequently increasing algal blooms or water hyacinth. Decay and death of vegetation of water hyacinth in huge masses end up deteriorating the quantity and quality of potable water while increasing the costs for treatment of drinking water (Kaufman and Kaufman, 2013). One enormous result about globalization aside out of the international motion of products then people is the conduction on wildlife. The introduction over specific kind into a modern surroundings do have a quantity concerning results, too invasive results. Some species might also furnish wonderful penalties namely per the latter ordinary environment, however partial cause economic harm, environmental harms and have an effect on human health.

Water hyacinth and its floating mats are known for supporting organisms that determine human health. The capability of its mas of semi-submerged stems and leaves, free floating fibrous roots end up decreasing water currents while increasing the habitat for breeding mosquitos that cause malaria. These invasive species also end up clogging waterways because of the rapid rate of propagation and reproduction (Kaufman and Kaufman, 2013). The density of these mats end up disrupting subsistence and socio-economic activities such as tourism, fisheries, recreation, and boat and ship navigation due to the clogging of water pipes or blocking of waterways. These floating mats end up limiting the accessibility to feeding, nursery, and breeding grounds for economically significant marine species.
