Water Pollution In South America Essays On Global Warming

Abstract

Background

Chile has recently been reclassified by the World Bank from an upper-middle-income country to a high-income country. There has been great progress in the last 20 to 30 years in relation to air and water pollution in Chile. Yet after 25 years of unrestrained growth, there remain clear challenges posed by air and water pollution, as well as climate change.

Objective

The aim of this study was to review environmental health in Chile.

Methods

In late 2013, a 3-day workshop on environmental health was held in Santiago, Chile, bringing together researchers and government policymakers. As a follow-up to that workshop, here we review the progress made in environmental health in the past 20 to 30 years and discuss the challenges of the future. We focus on air and water pollution and climate change, which we believe are among the most important areas of environmental health in Chile.

Results

Air pollution in some cities remains among the highest in the continent. Potable water is generally available, but weak state supervision has led to serious outbreaks of infectious disease and ongoing issues with arsenic exposure in some regions. Climate change modeling in Chile is quite sophisticated, and a number of the impacts of climate change can be reasonably predicted in terms of which areas of the country are most likely to be affected by increased temperature and decreased availability of water, as well as expansion of vector territory. Some health effects, including changes in vector-borne diseases and excess heat mortality, can be predicted. However, there has yet to be an integration of such research with government planning.

Conclusions

Although great progress has been made, currently there are a number of problems. We suspect that the Chilean experience in environmental health may be of some use for other Latin American countries with rapid economic development.

Global Water Pollution: Causes, Impacts, and Solutions Essay

530 Words3 Pages

Water pollution has become a huge problem in many countries all over the world. It is known that water is a very significant factor in life, but if this water becomes contaminated, it will be very dangerous for the humanity and wildlife. Pollution is defined as ' to make fetid or unclear and dirty' (American College Dictionary). So, water pollution means the change in the water composition to be dirty or unclear. This essay will examine the causes of water pollution, the effect of that issue in life and how to overcome this problem.

Pollution of water in the world can be caused by several reasons. Firstly, direct reasons which impact immediately in the composition of water. For example, discharging the sewage water into the sea has…show more content…

As a result of all these causes of water pollution, there are some unwanted effects. First of all, this type of pollution definitely impacts the health of humanity, because many use large quantities of water for drinking or cooking. Thus, it is crucial to have pure water. Moreover, contaminated water can damage wildlife. The second effect of water pollution is the environmental influence such as the odour of water and the terrible sights on beaches or rivers. Finally, there are economical consequences which can occur when the government starts to cleanup this contamination as it might spend an enormous amount of time and money. Furthermore, wasting fresh water is an intractable problem that may be faced when they minimize the volume of dirty water. Therefore, the prevention is much better and cheaper than the cleanup (Miller, G. T. 2007).

Everyone in society can do some helpful things to deal with the water pollution issue. Governments can control oil transfer in the sea and put more laws and severe penalties on defaulting companies. Also, they can find another solution for sewage rather than dispose of it in the sea. In addition, traders should not throw industrial waste and chemical products in the sea. Moreover, human beings have a considerable part by not disposing plastic items down the toilet, and never throw oil products down the drain either (Australian Marine Conservation Society. 2004). Such solutions will
