Impacts of Environmental Degradation

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world.

A s with production and use of any fuels, aspects of biofuel production and use have benefits and adverse effects. This chapter discusses potential environmental effects from the production and use of algal biofuels, the potential influence of perceived or actual impacts on societal acceptance, and some of the health impacts potentially emanating from the specific environmental effects. Potential environmental effects discussed in this chapter include those resulting from land-use changes, water quality, net greenhousegas GHG emissions, air quality, biodiversity, waste generation, and effects from genetically engineered algae with an emphasis on new or enhanced traits. Where possible, this chapter discusses the potential for algal biofuels to improve aspects of sustainability compared to petroleum-based fuels and other biofuels and the potential for mitigating negative effects along the life cycle of algal biofuel. Environmental indicators of sustainability and data to be collected to assess sustainability are suggested.

One of the most compelling reasons for studying environmental science and management is the fact that, in the view of many leading authorities, we are now experiencing an environmental crisis; indeed, many authors have claimed that the present environmental crisis is unprecedented in its magnitude, pace and severity Park Awareness of this environmental crisis has grown since the s, partly as a result of the prominence given to major so-called 'environmental' disasters such as the Sahelian droughts of the s and s and the nuclear accident at Chernobyl in Consequently, a wide range of environmental problems has emerged; those problems include anthropogenic climate change 'global warming' , the depletion of stratospheric ozone the 'ozone hole' , the acidification of surface waters 'acid rain' , the destruction of tropical forests, the depletion and extinction of species, and the precipitous decline of biodiversity. Yet, while all of these problems have physical environmental manifestations, their causes - and their potential solutions - are invariably bound up with human attitudes, beliefs, values, needs, desires, expectations, and behaviours. Thus the symptoms of the environmental crisis cannot be regarded purely as physical problems requiring solutions by environmental 'specialists'; instead, they are intrinsically human problems and they are intimately related to the question of what it means to be human. At this point, a very brief overview of the environmental crisis may be helpful. It is important to emphasise that a wide range of views about the nature and severity of the current environmental crisis exists, and some of the issues are highly controversial.

Environmental Degradation and Challenges Faced in 21st Century

The degradation of ecosystems is an environmental problem that diminishes the capacity of species to survive. The degradation of ecosystems due to overexploitation of their resources, though serving a short-term economic goal, has had direct negative effects on social welfare in the medium and long terms. As long as the ecosystem is not degraded, it represents a source of wealth for society, hence the importance of keeping it in good condition. One of the main causes that contributes to the degradation of ecosystems is the deforestation due to the advance of the agriculture frontier and inappropriate forest exploitation. More lands are deforested for commercial agriculture and live-stock rearing, and due to overexploitation of forest for wood and energy. In Nicaragua deforestation rates reach over , hectares per year and in Costa Rica over 18, hectares per year.

Environmental pollution is reaching worrying proportions worldwide. Urbanization and industrialization along with economic development have led to increase in energy consumption and waste discharges. The global environmental pollution, including greenhouse gas emissions and acid deposition, as well as water pollution and waste management is considered as international public health problems, which should be investigated from multiple perspectives including social, economic, legislation, and environmental engineering systems, as well as lifestyle habits helping health promotion and strengthening environmental systems to resist contamination [ 1 — 3 ]. Environmental pollutants have various adverse health effects from early life some of the most important harmful effects are perinatal disorders, infant mortality, respiratory disorders, allergy, malignancies, cardiovascular disorders, increase in stress oxidative, endothelial dysfunction, mental disorders, and various other harmful effects [ 4 , 5 ]. Though, short-term effects of environmental pollutants are usually highlighted, wide range of hazards of air pollution from early life and their possible implication on chronic non-communicable diseases of adulthood should be underscored. Numerous studies have exposed that environmental particulate exposure has been linked to increased risk of morbidity and mortality from many diseases, organ disturbances, cancers, and other chronic diseases [ 6 , 7 ]. Therefore it is time to take action and control the pollution.

Environmental Pollution: Health Effects and Operational Implications for Pollutants Removal

Environmental degradation comes about due to erosion and decline of the quality of the natural environment. It is caused directly or indirectly by anthropogenic activities that extract various environmental resources at a faster rate than they are replaced, and thus depleting them. On this regard, degradation means damage or reduction in quality of environmental features, primarily influenced by human activities.

All the human causes of global environmental change happen through a subset of proximate causes, which directly alter aspects of the environment in ways that have global effects. We begin this chapter by outlining and illustrating an approach to accounting for the major proximate causes of global change, and then proceed to the more difficult issue of explaining them. Three case studies illustrate the various ways human actions can contribute to global change and provide concrete background for the more theoretical discussion that follows.

Effects of environmental degradation:

 - В чем же чрезвычайность ситуации, из-за которой вы вытащили меня из ванной. Какое-то время Стратмор задумчиво нажимал на клавиши мышки, вмонтированной в столешницу письменного стола. После долгой паузы он наконец посмотрел ей в глаза и долго не отводил взгляда. - Назови мне самое большое время, которое ТРАНСТЕКСТ затрачивал на взламывание кода. Что за чепуха.

Когда Стратмор предпринимал какой-либо шаг, Танкадо стоял за сценой, дергая за веревочки. - Я обошел программу Сквозь строй, - простонал коммандер. - Но вы же не знали. Стратмор стукнул кулаком по столу. - Я должен был знать. Да взять хотя бы его электронное имя.  - Боже мой, Северная Дакота.

Causes and health consequences of environmental degradation and social injustice

Если бы ему удалось затеряться в центральной части города, у него был бы шанс спастись.

The primary cause of environmental degradation is human disturbance. Environmental changes are based on factors like urbanization, population and economic growth, increase in energy consumption and agricultural intensification. The degradation has adverse impacts on humans, plants, animals and micro-organisms.


Clovis G.

The major factor of environmental degradation is human (modern urbanization, industrialization, overpopulation growth, deforestation, etc.) and natural (flood, typhoons, droughts, rising temperatures, fires, etc.) cause. Different causes of environmental degradation.



You do not have to look far to see the impacts of environmental degradation on the Earth.


Lori H.

Environmental degradation is the disintegration of the earth or deterioration of the environment through the consumption of assets, for example, air, water and.
