The way humans are using water is not sustainable. Water aquifers underground are being dried up daily. Once an aquifer reaches a certain low, it may or may not be able to come back. So, basically, water is being taken out of aquifers at a faster rate than which it can replenish itself (Sin aqua non; Water). Although, a lot of water that comes from aquifers is used for drinking, most of the water being used is for irrigation of crops. The water used for irrigation has created great gains for the agriculture and food industry. This water has been used to create food security. However, it is being threatened by other businesses that use it for industrial purposes (Hanjra). Once these aquifers and the other sources of water dry up, there will be no more accessible water. Not knowing when the water levels become too low is a major issue; however, if they are being used resourcefully, there should not be a reason to agonize over the levels. The Economist explains that diets are one of the main causes for water scarcity.
The main causes are open mines and factories, who dump waste water containing toxic substances into waterways, and have caused permanent damage to ecosystems. Ocean pollution is also increasing, with the ocean eventually collecting all of the sewage, sediment from forest clearing, fertilizer and pesticide run-off. The oceans play a key role in our world, not only as a food source, but also in climate regulation. As the oceans climate regulation weakens, the extremer temperature variation has been
How can societies meet their infinite amounts of needs and desires on a finite planet? This is not only an economic problem but also an environmental and a social problem that all societies have to face. Sustainable development is an organizing solution for humans to live on a planet with limited resources. The term Sustainable Development was introduced by the United Nations in the Brundtland Report (1987). The concept of sustainable development has can be broken down into three parts: economical development, environmental development and social development. Canada is well known for its natural resources, diverse cultures and welfare services. However, without a sustainable strategy Canada will rapidly use up its resources. Furthermore it will lead to negative economical, environmental and social outcomes. This brings up the question “What should Canada’s role be in this global issue?” Canada’s role should be to strive to develop economically, environmentally and socially in a more sustainable way, so that future generations will be provided with a good quality of life. In order to become sustainable Canada must minimize the gap between the wealthy and the poor, reduce greenhouse gases and promote multiculturalism.
Under conditions of water scarcity and intensive development, the degradation of water quality constitutes a critical problem.
Humans often take the water cycle for granted and assume that fresh water will always be available for drinking, cooking, farming, etc. Unfortunately, the ways in which society uses water is contributing to the reduction in fresh water available for human use. First of all, the use of hydroelectric power, though a clean source of energy, is negatively affecting the ecosystems in which the plant is stationed. The waterway must be dammed in order to maximize the potential energy of the water, but this often affects the function of the waterway upstream and downstream. For example, the build-up of water above the dam may create a lake where silt can build up while a lack of water below the dam eliminates habitats. Moreover, plants and aquatic animals that previously inhabited the waterway “may find themselves with too much or too little water, and migrating fish cannot get through the dams” (Humans and the water cycle). Not only does hydroelectricity disrupt the water cycle, but irrigation does as well. “Irrigation is the artificial watering of land that does not get enough water through rainfall” (Humans and the water cycle). Most countries that use irrigation have dry land or they require more water to grow more plants for their increasing population. The issue with irrigation is that it removes relatively clean water from its natural source and essentially pollutes it. The fertilizer in
In addition, fresh water bodies have decreased due to global warming activities due to the changes in weather patterns. This has been caused by the sporadic rainfall leading to fresh water bodies not being replenished. From this, it is evident that the water is being overused by humans due to the growing population demands. The use of chemicals in farming practices has affected the quality of soils for farming. This has led to augmented food shortage and many of the lands are becoming arid. Lastly, humans are overexploiting the natural minerals like oil, gold and diamond, which are scarce commodities. For example, oil generation takes millions of years to form. However, man has continued to mine the resource at a faster rate due to urbanization.
On the one hand, water pollution poses serious threats to people’s living and health conditions. For example, according to the US Geological Survey, California has one-fifth of the water supply systems exceed the standard amount of perchlorate in the past decade. Some remote schools in Tulare County have denied students access to drinking fountains, and a school district of 260 students spends $ 10,000 or more per year on drinking water. The school will order bottled water, store and distribute it to each classroom, and collect empty bottles（Worldjournal）. A case in point is when the water resources are polluted in California, the state’s development would also be damaged. Firstly, the citizens’ living quality would be declined，because of water is so indispensable in people’s daily
"The term 'sustainability' should be viewed as humanity's target goal of human-ecosystem equilibrium, while 'sustainable development' refers to the holistic approach and temporal processes that lead us to the end point of sustainability." Despite the increased popularity of the use of the term
People don’t appreciated the many advantages that comes with having clean potable water to use, taking it for granted. A lot of clean useful water is wasted by humans all the time that people don’t care about saving water because they have easy access to it. Clean and safe drinkable water resources are getting scarce as the population grows. The world is facing many problems, but the most important needed to survive, is water. Water is getting low in many countries, therefore habitants are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages; meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands. Water shortage affects the agricultural sector, so as a consequence the price for production
Sustainability is a concept with a diverse array of meanings and definitions – a widely used glamorous, ambiguous, ambivalent and vague concept that is used by different stakeholder groups in various ways. Presumably to avoid noodling over a terminology or to avoid the confrontation with a definition, most widely the concept is broken down a planning process (c.f. e.g. Döring & Muraca, 2010). That is why most common sustainability is understood as sustainable development.1
Sustainable development refers to not only meet the needs of contemporary people, but also not compromising the ability of future generations to meet development needs.Sustainable development and environmental protection have established contact, not the same. Environmental protection is an important aspect of sustainable development. The core of sustainable development is development, but requires strict control of the population, improve population quality and protect the environment for the conduct of economic and social development under the premise of sustainable use of resources.
In class we discussed what sustainable development meant to us; each group had its own definition. Our group’s definition was that sustainable development is for the long term for future generations, for the basic needs such as food, clothing, shelter, and job. The basic will increase over time and our resources will diminish, which why sustainable development is important. Sustainable development is important for future generations so that they end up with a world better than ours. Sustainable development is achievable if society works together to meet everyone’s basic needs and create a better world.
Sustainable development means that the present generations should be able to make use of resources to live better lives in such a manner that it doesn’t compromise the ability of future generations to survive and make better lives for themselves as well. For sustainable development to occur, there needs to be sustainable economic, ecological and community development. Society needs to be educated about ways in which they can use resources, especially natural, in such a manner that it doesn’t cause harm to the environment and put future generations lives at risk.
‘Development that meets the needs of the present with the ability for the future generation to meet their own needs.’ (World Commission on Environment and Development, 1987) Sustainable development requires three key components: economy, society and environment, sustainable development can be success through striking balance in those factors. These three components are indispensible, they compel to depend on each other. On the other words, we can only gain a decent and energetic environment and society if the economy is strong with a healthy a stable growth rate.
