Freshwater Essay

1. Introduction Colored dissolved organic matter (CDOM) is an optically active component of total dissolved organic matter (DOM), absorbing light strongly in the UV and visible spectral range, hence influencing light availability in the aquatic environments [1]. Although CDOM protects marine biota from the harmful effects of UV radiation in surface waters [2], it can also adversely affect primary production and the ecosystem health by reducing the quality and the amount of photosynthetically active

Syrians live in refugee camps”(Oxfam Policy-International, 2013). The overwhelming increase in population, as a result of the Syrian crisis, has placed a major strain on Jordan’s economic infrastructure, specifically through the region’s production of freshwater resources. According to the United Nations Inter-Agency on Water (UNIA), Jordan is ranked one of the ten water-depressed countries in the world. The growth in Syrian population has increased this strain, with UN estimates revealing that it may take

the fresh water areas, the overall ecology of fish habitats and migratory routes are disappearing due to human activities. It is therefore difficult to meet the protein requirement of the population from the freshwater sub-sector alone. Notwithstanding, priority is still given to the freshwater for fishery despite the fact that marine and brackish water fisherysub-sectors constitute greater proportion of foreign exchange earnings and development budget. This is reflected in the number of fishery development

Historically, the Tampa Bay area is associated with a series of “water wars.” Although the root of this conflict is not particularly clear. It is speculated that the creation of Pinellas County or an increased demand on a limited resource (water) could be the premise. Regardless of the reason, the political and legal battles over water supply in the Tampa Bay area have left their mark on the region. Rand (2003) elaborates on “the water wars” here, “In the 1970s, Hillsborough and Pinellas [counties]

cooking, bathing, cleaning, industrial purposes and sanitation. When the demand for water exceeds its supply for an extended period of time, scientists refer to the situation as water stress. This serious issue leads to lower quantity and quality of freshwater resources. While most causes are human-related, others are uncontrollable. Population Growth * An increase in people means more water usage for bathing, washing dishes, cooking and other activities. World population tripled in the 1900s, resulting

water all forms of water resources are not directly accessible or easy to mobilize. This may consist of watercourses or groundwater. These are the waters collected by Rivers and rivers that account for most of the total flow. Just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. In essence, only 0.007 percent of the planet 's water is available to fuel and feed its 6.8 billion people (national geographic) Water coverage is only 61% in sub-Saharan

Schistosomiasis is a parasitic disease caused by trematode flatworms. This parasitic infection endemic mostly impact impoverished nations that do not have clean running water. Schistosomiasis is commonly found in 76 countries around the world. In under developed countries of Africa Schistosomiasis, is second only to malaria as a cause of morbidity. Schistosomiasis affects approximately 240 million people globally (Hotez, 2013). The main areas affected are the regions near the equator, parts of the

Example: red horse. Amphidromous: Fishes that come under this group are born in freshwater and are drifted by the water current into the river then it again returns back to freshwater thus developing into an adult and start reproduction. Example: mountain mullet. Oceanodromous: These group of fishes are born near the breeding ground, and by the current of water they get drifted in

the rise in large scale industrial activity such as mining and metal processing has lead to an explosion in human productivity. However, the repercussion of this expansion is the disruption of global habitats, resulting in the contamination of freshwater environments by heavy metal pollutants. The level of pollution by heavy metals is further escalated by factors such as acid rain which increase the erosion rate of metals thus leading to the introduction of more heavy metal pollutants (Tchouwou

“The skill, good judgment, and the polite behavior that is expected from a person who is trained to do a job”- this is what defined by popular “MERRIAM-WEBSTER” dictionary. As far as what we think about the term professionalism is that it is an application of mixture of abilities, skills, knowledge and commitments to an organization to which he/she is assigned. Every organization which recruits a person, expect the above qualities as a part of their professionalism. We will find almost the same definitions
