Essay causes environmental degradation
These creatures are called area specific. It gets to be more troublesome for the wildlife to get the assets they need in order to survive. The environment goes on, even though the animals and plant life are not there to help sustain it properly. Land Disturbance: A more basic cause of environmental degradation is land damage.
Environmental Pollution And Degradation
Numerous weedy plant species, for example, garlic mustard, are both foreign and obtrusive. A rupture in the environmental surroundings provides for them a chance to start growing and spreading. These plants can assume control over nature, eliminating the local greenery. Whole environments can be destroyed because of these invasive species. Pollution: Pollution, in whatever form, whether it is air, water, land or noise is harmful for the environment. Air pollution pollutes the air that we breathe which causes health issues. Water pollution degrades the quality of water that we use for drinking purposes.
Environmental Problems Essays
Noise pollution can cause irreparable damage to our ears when exposed to continuous large sounds like honking of vehicles on a busy road or machines producing large noise in a factory or a mill. Overpopulation: Rapid population growth puts strain on natural resources which results in degradation of our environment. Mortality rate has gone down due to better medical facilities which has resulted in increased lifespan.
More population simple means more demand for food, clothes and shelter. You need more space to grow food and provide homes to millions of people. This results in deforestation which is another factor of environmental degradation. Landfills: Landfills pollute the environment and destroy the beauty of the city. Landfills come within the city due the large amount of waste that gets generated by households, industries, factories and hospitals.
Landfills pose a great risk to the health of the environment and the people who live there. Landfills produce foul smell when burned and cause huge environmental degradation. Deforestation: Deforestation is the cutting down of trees to make way for more homes and industries.
Rapid growth in population and urban sprawl are two of the major causes of deforestation. Apart from that, use of forest land for agriculture, animal grazing, harvest for fuel wood and logging are some of the other causes of deforestation. Deforestation contributes to global warming as decreased forest size puts carbon back into the environment. This can either come to fruition through physical demolition as the result of a specific disaster, or by the long term degradation of assets by the presentation of an obtrusive foreign species to the environment.
The latter frequently happens after tidal waves, when reptiles and bugs are washed ashore.
Earth itself causes ecological issues, as well. While environmental degradation is most normally connected with the things that people do, the truth of the matter is that the environment is always changing. Research on the human dimensions of global environmental change is concerned with the human causes of change, the consequences of such changes for individuals and societal groups, and the ways in which humans respond to the changes. The causes include processes like industrialization and urbanization, which themselves are driven by human needs and wants, such as the needs for water, food, and shelter.
The impacts include water and food shortages, floods and droughts, health risks, and conflicts about resources.
Climate change and environmental degradation
Responses to these changes include adaptation, for example, through planting different crops, and even migration from areas most affected by environmental changes and mitigation, for example, by reducing emissions of gases into the atmosphere. Individuals and teams carry out research on the human dimensions of global environmental change in many universities and research institutes worldwide. The range of social science disciplines involved in research related to global environmental change is wide, including political scientists studying the effectiveness of environmental agreements, demographers looking at the links between population growth and environmental change, economists considering the possibilities for delinking economic growth and environmental impacts, anthropologists debating human needs and wants and global environmental change, and scholars looking at the psychological dimensions of global environmental change.
Environmental degradation has been cited as one of four root causes of refugee flows, together with political instability economic tensions and ethnic conflict UNHCR The number of environmental refugees is estimated to be 10 million out of the 17 million official refugees and more than half of these are believed to be in sub-Saharan Africa Westing But the numbers may be far greater and appear to be rapidly increasing.
The greatest effects of climate change may be to displace millions of people through shoreline erosion, coastal flooding and agricultural failures.
Although the World Commission on Environment and Development identified environmentally induced population movements as a recent phenomenon WCED , there is much evidence that people have had to move from land affected by natural disasters, warfare and mismanagement throughout—and before—history. Despite the size of the problem, there has been relatively little empirical research on the role of environmental change in population movements.
Some of this movement is across national borders, but it is estimated that for every individual who moves across an international border, there are two or three persons who have to move within their country. These are internally displaced persons Myers There are a number of difficulties in understanding the role of the environment in causing people to move. It is difficult to isolate the role of environment in this decision unless there is a specific environmental stress such as an earthquake or flood from which people are fleeing and after which they are likely to return.
Development projects such as dams and irrigation schemes have often involved enforced resettlement. In India, it is estimated that over 20 million people have been displaced by development projects since the s Fornos Environmental degradation perpetuates environmental injustice by making the damage and losses suffered by poor and marginalized people worse than would otherwise be the case.
Moreover, both poverty and inadequate social development contribute to and are caused by environmental degradation and injustice. Consequently, while 1 billion people overconsume products, 1 billion people die of hunger and a further 1 billion are malnourished. Yet, food prices have been increasing rapidly, and, in , these led to riots across the globe.
Additionally, 1 billion people lack clean drinking water in their homes, 2. Furthermore, 15 million people lose their lives annually because they cannot afford drugs or access them cheaply Newsweek, 4—11 June p. Each of these factors exacerbates the hardships encountered during a disaster, regardless of its cause. Green social workers declare this situation unacceptable and work toward eliminating the inequalities that give rise to these avoidable outcomes. Moreover, rising greenhouse gas emissions based on burning fossil fuels for energy and industrial production purposes are contributing to climate change.
With climate change, extreme weather events associated with heat waves, cold snaps, and heavy precipitation can exacerbate the environmental damage and health problems caused by so-called natural events such as flooding and drought, which are exacerbated by inappropriate urbanization practices such as building housing on flood plains Pearce, Questioning the links between industrial pollution and damage to the environment has been obvious to a number of thinkers for some time. Indigenous people have decried the destruction of pristine hinterlands in North America, South America, and Australasia because their exploitation for minerals and other commodities has left them with few jobs, fewer resources, and lost autonomy as their national governments collaborate with multinational companies based elsewhere to determine their development trajectories Escobar, These usually disrespect indigenous peoples' priorities and concerns, thereby promoting environmental injustice.
Social workers often get involved in raising consciousness about the issues and resisting these measures alongside local residents protecting their communities Dominelli, a. Moreover, social workers are demanding a place at the table in key decision-making fora such as the climate change talks held under the auspices of the UN Dominelli, Environmental degradation intensifies the vulnerabilities of poor and marginalized people to disaster and its impact upon their lives and livelihoods. Social workers assist communities in formulating and implementing RRS and sustainable forms of social development.
Social workers are also involved in delivering humanitarian aid to those affected by disasters and taking care of people who reach humanitarian aid camps in search of safety. RRS are more effective if proposed activities engage people through their everyday life routines instead of being treated as special events. Involving people in making decisions about what happens in reducing risks and enhancing resilience for themselves and their communities facilitates the coproduction of knowledge and formation of partnerships that cross disciplinary divides and allow for contact between local people and subject specialists.
The trees shading the edge of the beach were predominantly coconut trees, and the women drew their water from a shallow village well. A rough gravel road of 2 km permitted access from the closest town suburb. In the five years leading up to national independence in , increasing numbers of houses were being built on land. Sites were determined by negotiation between families and followed no plan. Around the same time the village was connected to town services: water piped to communal stand-pipes , electricity to street lights along the beach , and several telephones had been connected e.
By shady trees had taken advantage of more generous availability of water and surrounded the majority of houses extending up the nearby slopes; the houses continued to be haphazardly placed with no planned road access, drainage, or sanitation. Electricity made television accessible and was connected to many houses, but being individually metered was often unavailable. Services had not matched growth; there was no plan in place for street layout, drainage, or sewage, and no there was no garbage collection. The connection of piped water, of electric light, or telephones might be counted as developments consistent with improvement in Community Health.
In Pari, however, the water supply has been intermittent and inadequate for the increased population; payments for water and power falter, making them inaccessible; and pipes and power lines are tapped illegally. Telephone lines have been sabotaged for their copper wire, and mobile phones are more reliable but expensive.
After the 2 km road from the closest town suburb was tarred, it quickly became dangerously pot-holed. The town of Port Moresby began to grow rapidly after , and brought opportunities for employment. The availability of cash allowed the purchase of new food items rice, tinned fish, and alcohol and clothing, tools, and transport. In the s Pari men were in demand as carpenters, and were employed by firms profiting from a buoyant housing industry.
Other enterprises were tried, and some exploited traditional skills such as dancing for overseas tourists or fabricating shell bangles and necklaces to sell in the town. Edited by , The major environmental degradation comes from noise.
Windmills tend to hum or whine, and several together can be annoying. Modern wind generators are much less annoying. Another annoyance is that metal blades interfere with television reception. The television signals bounce off the blades and into the TV intermittently, so a disturbing pattern is superimposed on the picture. Blades made of wood, plastic, or cloth do not cause TV interference but do not last as long as metal ones. Incidents of birds hitting blades have been reported. Whistles emitting sound at frequencies above human hearing are expected to keep birds away.
In the United States objections have been raised to the appearance of wind generators—especially to the towers.

This article discusses how environmental degradation has been conceptualized and the initiatives that have arisen in response. I refer to environmental degradation as human instigated damage and destruction of what are commonly referred to as natural resources: water, land, trees, animals, and air. Degradation has been conceptualized in multiple ways, including neo-Malthusian explanations related to population growth, and explanations deriving from political ecology that site resource appropriation.
As environmental conservation interventions sought to protect biodiversity throughout the s and s, governments and international NGOs were interested in melding conservation with the elusive goal of economic growth and development. This article reviews the literature on environmental degradation and the literature on development, as well as the intersection of the two.
