...AE 3B Problem Solution Essay Assignment Essay’s topic: Water scarcity is one of the key environmental issue of our time. Identify some major causes of water scarcity and describe two solutions. Water plays an important role in developing and maintaining healthy ecosystems. However, water scarcity is an increasing and widespread phenomenon in many countries in the world. Water scarcity refers to either the lack of enough water or lack of access to safe water. The shortage of water is turning out to be more pressing than prediction. This essay will identify some major causes of water scarcity and specifically focus on the solutions of enhancing water stewardship and protecting wetlands. The first major cause of water scarcity is overpopulation. The rapid growth of population has led to a massive demand of water. In the last 50 years, the human population has increased more than double. Moreover, accompanying with population growth are economic development and industrialization. Population growth also results in the need of food, home and clothing, which has added more pressure on the availability of freshwater while water supplies are limited and insufficiently managed. If the consumption rate of water has continued at unsustainable levels, by 2025, two-third of the world population may face water shortage, and ecosystem around the world will suffer even more. Water pollution is the second major cause of water scarcity. It is the result of many reasons, including pesticides...

...Position on Water Issues Student Name: Student Number: Tutor: Topic: Should Canada share its freshwater with the United States? Semester 1: 2011/12 Table of Contents Introduction 3 Fresh water in Canada 4 Water in the US 5 The Ethics of water 5 Conclusion 7 References 9 Introduction The earth is a watery planet; three-quarters of earth’s surface is covered with water. And this is as it should be; the earth is the only known plant that supports life which is dependent on water. Water is found in oceans, rivers, lakes, glaciers, under-ground and in the atmosphere. (The Atlas of Canada, 2011) However 97% of the earth’s water is salty, and cannot support land based life which occupies a quarter of the earth’s surface. Therefore land based life has a disproportional amount of fresh water for its usage at only 3% compared to sea life. Water naturally occurs in three states: solid- glaciers, ice, snow; liquid - surface water, groundwater, soil moisture; groundwater and; gas- as water vapor that normally cools and drops to the ground as rain, snow or fog. Fresh water is defined as water that has less than 1000 milligrams per litre of the solids that dissolve in water. Of the worlds freshwater, about 99 % of the fresh water in the world is found in glaciers, ice-fields, or underground. This further decreases the amount of fresh water available to land based life (Environment Canada, 2011). Fresh water is a basic necessity...

...Water is the foundation of life. It is only in areas that contain liquid water in which life exists. Ancient societies used to cherish water. Some would even worship water and build their lives around it. Recognizing the vitality of water management was of key importance thus water was common and universal. Although everyone is dependant upon it, in today’s society the appreciation of water has greatly diminished as water resources are taken advantage of and exhausted. Ninety-seven percent of the Earth’s water is salt (Barlow & Clarke, 2002). Just a mere three percent of the Earth’s water is fresh water and much of it has been polluted. Despite the fact that water is crucial for survival, this basic need is one that is not afforded to all. On the basis of profit, water has become a life and death situation. Wealthy people and countries with the ability to pay will have access to water. Those who cannot afford to pay for the basic need of water, that has now become a commodity, will go without and suffer in poverty. Drinking water scarcity is a huge pandemic. Due to human’s selfish and non-sustainable impact of the water supply there is a global water crisis- the world is running out of water. Amongst developed countries and multinational corporations, there is a damaging mentality that water can be used without limit as long as there are no immediate or significant impacts. The environmental impact of this way of thinking is detrimental. In reality, all of the negative effects...

...Water Wars There can be no life on Earth without water. It is indispensable for human health and well-being, for food production, and economic activities. But despite its importance, water is rarely considered as a resource in the same way as others, for example oil. Water covers more than two thirds of our planet, so to many it may seem like there is more than enough, and in most parts of the world its availability is taken for granted. However, freshwater, what we drink, bath in, and irrigate our land with, is extremely scarce. Only around 3% of the world’s water is fresh water, and about two-thirds of that is contained by glaciers, rendering it not readily available for human use. Agriculture uses more water than any other source and wastes much of it due to inefficiencies. Today more than a billion people around the globe lack access to fresh water and many of the world’s water systems have become stressed. In addition, rivers, lakes, and aquifers are becoming too polluted to use, climate change is altering weather patterns, resulting in shortages, droughts and floods. The world’s population is rapidly increasing, and at the current consumption rate the situation will only get worse. So without improved and more effective management, the availability of fresh water will more than likely not keep up with demand. It is estimated that by 2025, two-thirds of the world’s population may face water shortages. Issues related to water scarcity can obstruct the ability of nations...

This process was made possible by advances in drilling technology in the past 100 years (www.energyfromshale.org/). Hydraulic fracturing of shale gas is also known as “fracking”. Hydraulic fracturing involves usage of vast amounts of a water mixture directed under high pressure at layers of shale to release the gas. The New York State Department of Environmental Conservation states that approximately 2.4 to 7.8 million gallons of water are needed per fracturing process. The water mixture contains...

Water, Our Finite Resources One of the crises that our environment is facing is fresh water scarcity which is a very serious issue and it affects our global environment. In the boundless black desert of space, the Earth which is always a blue-green oasis has a finite stock of fresh water (Lean, 2009). Water is the principal element for all socio-economic growth and for sustaining healthy ecosystems (“Water scarcity: The”, n.d.). Water scarcity is the product of an inequity between the supply of and demand for water supplies in a geographical area. Plainly put, water...

...Three Effects of Climate Change By: Nehanda Spencer Contents Introduction 2-4 Public Health 4-5 Water Crisis 6-7 Human Migration 7-8 Summary 9 Works Cited 10 Work Cited Pages 11-30 Introduction Well before the term climate change was used to describe the weather effects on the earth, I was informed about global warming. During high school when I was instructed to learn about global warming it was just a mere discussion based on the potential effects humans had on the climate. Approximately eight years later the suspected effects, of careless exertion of the earths resources among other influences, have drastically impacted the world and scientist have agreed that it is the cause of climate change. I was aware of climate change and I’ve witness many natural disasters over the years due to news broadcastings; such as hurricane Katrina, Washington’s mudslide and most recently Arkansas deadly tornado. However, I never truly grasp the importance of the earth’s current situation until I furthered my research in college. According to the ShowTime docu-series “Years of living dangerously” climate change is inevitable due to the amount of earth’s resources used verses those that are replenished. The documentary opened my eyes to the high tempatures that are spreading across the country and one of the biggest causes of climate change, which are green house gases. The tragic causes of these gases develop from the burning of fossil fuels...

...International Security The future of nation-state as the primary unit of action for world affairs can generally be said to be insecure. This may be mostly due to the increasingly world interconnection and also the move from a society monarchy to a communal one. The idea of globalisation has really intensified the interconnection globally which will lead to the world been interconnected to institutions of economics, politics and society. The challenges posed to nation-state by globalisation include; first, it reduces the ability of nation-state in influencing the economy in that all economic transactions are done in the global stage. Second it increases the transnational bodies which could be political, economic or combination of both. The third aspect is it allows for emergence of super and sub national power centres. Finally, there is the increasing world migrations and non-governmental organisations (NGOs) importance. The insecurity of the nation state has great impact on the US foreign and security policies. There are various ways in which this is affecting the US foreign and security policies; through the introduction of the globalisation system the US policies will be undermined and thus negatively impacting on its security. The United States will also lose its control in the international economy a factor which will lea to other countries undermining its policies. This gradual decline will also widen the scope of security and stability and hence nations will be able...

The implications of water scarcity An essay about the present problems and future implications of water scarcity, if the world do not change the utilization. A Clean Water Crisis The water we drink today has likely been around in one form or another since dinosaurs lived on the Earth, hundreds of millions of years ago. While the amount of freshwater on the planet has remained fairly constant over time—continually recycled through the atmosphere—the population has exploded. This means that every year competition for a clean supply of water for drinking, cooking, bathing, and sustaining life intensifies. Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is ice or ocean. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. All in all, only 0.007 percent of the planet's water is available to fuel and feed its 6.8 billion people. In the following pages I am going to show the 4 main implications of water scarcity. Implications because of population growth Because of population growth and economic development, water resources in many parts of the world are pushed to their natural limits...

...------------------------------------------------- Water in the UAE ------------------------------------------------- Impact Achievements and Ways Forward Introduction Water is the resource that sustains all life on earth and is a key element of sustainable development. It is essential if human beings are to enjoy healthy and safe lives or realize social and economic development. Ecosystems are also inextricably linked with water. Water sustains humans’ health, food production, and economic development. But only 3 percent of Earth’s water is salt-free, or fresh water. Moreover, nearly 70 percent of fresh water is locked in glaciers and icebergs, and is not available for human use. The fresh water that is available comes from rain or from rivers, lakes, springs, and some groundwater reserves, such as aquifers. With the increasing demand on water for all aspects of sustainable development, water is becoming very scares all around the world! * Around 700 million people in 43 countries suffer today from water scarcity. * By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world's population could be living under water stressed conditions. * With the existing climate change scenario, almost half the world's population will be living in areas of high water stress by 2030, including between 75 million and 250 million people in Africa. In addition, water scarcity in some arid and semi-arid places will displace...

...| A Drink of Water | Christopher J. Barrett | | SCI-275 | 3/24/2013 | | Sanitation and drinking-water are universally accepted as being essential for human life, dignity and human development (World Health Organization, 2012). Water is required for life to exist; it is the most basic of sustaining building blocks. Global access to clean (sanitary) and sustainable water supplies continues to be a challenge in an age of ever-increasing population and development. Despite the ongoing challenge, the scarcity of global water resources has only begun to be addressed by the United Nations and other not-for-profit charitable organizations. One of the most important recent milestones has been the recognition in July 2010 by the United Nations General Assembly of the human right to water and sanitation. The Assembly recognized the right of every human being to have access to sufficient water for personal and domestic uses (between 50 and 100 liters of water per person per day), which must be safe, acceptable and affordable (water costs should not exceed 3 per cent of household income), and physically accessible (the water source has to be within 1,000 meters of the home and collection time should not exceed 30 minutes) (United Nations, 2013). UN system activities specially focus on the sustainable development of fragile and finite freshwater resources, which are under increasing stress from population growth, pollution and the demands of...
