Maps Show Humans’ Growing Impact on the Planet

Apart from wind and rain, a major impact is from the associated storm surge and storm waves. These have been responsible for major loss of life particularly in low lying densely populated coastal areas such as Bangladesh or China. Tsunamis are quite a different phenomenon and are often associated with subsea earth movements.

However, their speed and height can cause extensive coastal destruction with little warning and some distance from their origin see: Tsunami. Further details can be found in Extreme storms and Natural causes of coastal erosion. The composition and structure of the fauna, flora and habitats of coastal seas has been changing at an unusual rate in the last few decades, due to changes in the global climate, invasive species and an increase in human activities.

The unusual rapid rate of change, rather than the nature of the change itself, is the reason for the deterioration of many environments; over the last 50 years the rate and extent of this deterioration has been unprecedented, as were the consequences on biological diversity. The term biodiversity is used by the Convention on Biological Diversity to refer to all aspects of variability evident within the living world, including diversity within and between individuals, populations, species, communities, and ecosystems.

The term is commonly used loosely to refer to all species and habitats in some given area, or even on the Earth overall. In fact, it relates to environmental attributes, often species or species groups, which can be sampled and whose modification is supposed to reflect a change of biological diversity. What primarily matters, is the capacity of ecosystems to fulfil their role within the biosphere.

The notion of functional diversity is useful in that it provides insight into the resilience of ecosystems and how changes affect them. There are many causes to losses of marine biodiversityespecially in the coastal waters of industrialised countries. The most drastic loss impact of human activity habitat destruction through the erection of engineering and drainage works, which disturb the physical integrity of coastal and marine systems, as the habitat itself is changed to a point where the ecosystem loses its identity and fulfils a completely different function as before.

Poor 3rd grade essay writing rubric management, including the uncontrolled exploitation of corals and molluscs and the by-catch of large numbers of non-target species in fisheries is another important aspect of the detrimental exploitation of marine living resources.

This is further illustrated in the article Effects of fisheries on European marine biodiversity. The underlying cause is the lack of an integrated approach to coastal zone management, leading to impoverished functioning [10]. As a consequence, the productivity of fisheries and such important ecosystems such as mangroves and coral reefs has been depressed, with detrimental impact on local human communities. In general, estuaries and salt marshesmangrove forests, and sea grass beds such as posidinia near cities and towns are severely degraded worldwide with many species being threatened.

The increasingly observed worldwide bleaching of corals could lead to massive ecological changes for coral reefs and other marine ecosystems. Living organisms play an impact of human activity role in biogeochemical cycles through coastal systems.

They are themselves vulnerable to rapid changes which take place in the coastal zone due to anthropogenic activities, but changes in the structure of populations of organisms will in turn affect the geochemistry of the habitat, to a point where such cycles might become dysfunctional. The consequences of such changes taking place in coastal ecosystems may have consequences at global level leading to an unbalance in fluxes of energy and minerals at the interface between land and sea [11].

The dynamics of such systems are very high and complex meaning that conservation is not just concerned with fixing the coast line to its physical actual limits, fighting erosion and sea level rise. Because coastal systems are alive, they are able to cope with changes of any sorts, but what counts is more the rate of change than the nature of the change. What makes the anthropocene unique is the rapidity of changes inflicted by humans to natural systems. Threats of all sorts from human activities onto ecosystems are now well documented but action remains difficult and uncertain because of a lack of understanding of the scale and of the speed of observed changes.

The most relevant linkages between activities and ecosystem components are prioritised by applying semi quantative scores to each of the linkages.

Impact of human activity

Doing so, the results contribute to the understanding of impact of activities, and the possible impact on ecosystem services and ecosystem valuation relation to the PhD study of Sophie Vonk. Several field surveys were carried out to these areas during the period between March and February over 23 months for acquiring all possible information about the current situation and to explore the impact of human activities along the canal banks on the canal ecosystem. Preliminary field investigations showed great amounts of discharged wastes at several locations to the canal water creating unique conditions, which vary with changes of volume and properties of the discharged wastes.

Rotifer and green algae for example demonstrated seasonal variable response to the ecological variations. Myriophyllum spicatum, Potamageton nodsus and Polygonum Salicfolium were the most common types of recorded weed. The Myriophyllum spicatum is the dominant submerged plant. It is a huge problem in many developing countries because it is destroying natural habitats, yet it seems to be one of the only ways that people can make enough money to support their families.

The New York Times recently ran an article about individuals in Malawi illegally cutting down trees change dissertation committe chair order to make enough money for food. One individual states, "We have no money to raise our families. We have nowhere to run, nothing else to do. So we have to cut the trees to feed our families.

The current rate of deforestation in Malawi is 2. Wines The degradation of the environment will affect both poor and industrialized nations. However, The developing nations will be the ones that are affected the most by the degradation of the environment by increasing poverty, reducing labor productivity, and exacerbating the current economic social crisis Mapping Developing nations do not have the resources to help their citizens find an alternative to use nature for survival.

Educating individuals in developing countries about the need to preserve biodiversity is a must for ensuring human survival. Educating locals on the impact people are making on the environment and showing people how they can live in equilibrium with nature, will help preserve biodiversity without causing further oppression. Many times individuals do not realize that there are alternative ways of obtaining money that do not put the environment into jeopardy.

For example, in the case in Malawiif the locals were to obtain honey from beehives found in the forests they would be able to make more money than they would by selling wood Wines General education in developing countries is very important to biodiversity even if it does not focus directly on sustainable living.

There have been significant studies that have shown that educating and empowering women lead to a decrease in birthrates which would make a huge impact on population growth, especially since developing nations have a higher birthrate compared to industrialized nations. Simply educating individuals, all individuals, not just impoverished ones, about their impacts on biodiversity is a step in the right direction.

Eldredge Governmental Actions. Although there are actions individuals can make that can assist in helping the biodiversity problem, it is important for governments to take actions that will provide a larger scale effect on saving biodiversity. The George W. Bush administration is not known for protecting the environment. President Bush has eliminated the roadless rule, which was a rule that kept logging and roads from being present in 60 million acres of national forests.

Bush has also cut 42 million acres of critical impact of human activity from the 83 million acres that are needed for threatened and endangered species. There has been a great decrease in the amount of designated wilderness in the United States. Bush designatedacres as wilderness areas compared to 9. There has also been a decrease in the number of species that were added to the endangered species list; Bush has added 31 species, ReaganBush Seniorand Clinton Wetsone et al.

Bush made another decision against the environment by not ratifying the Kyoto protocol. The Kyoto protocol is a treaty that agrees to manage climate change on earth by reducing the amount of carbon dioxide and other greenhouse gasses from entering the atmosphere or to employ emissions trading when governments provide an incentive for individuals to reduce the amount of emissions Kyoto Areas with no or low human footprint are also fast disappearing.

But byhuman activities had encroached upon 9. Regions with no or low human footprint now occur in deserts like the Sahara, Gobi and Australian deserts, and the most remote moist tropical forests of the Congo basins. Much of the Amazon, too, has low human pressure, the study found, despite being encroached by settlements, agriculture, and waterways and roads. Table 4. Sedimentation should be factored into strategies to protect water resources More Wastes that people dispose of can pollute the air, the land, and water resources.

They affect the quality of rainwater and of water resources both above and below ground, and damage natural systems. The causes of freshwater pollution are varied and include industrial wastes, sewage, runoff from farmland, cities, and factory effluents, and the build-up of sediment. Emissions from factories and vehicles are released into the air. They can travel long distances before falling to the ground, for instance in the form of acid rain. The emissions create acidic conditions that damage ecosystemsincluding forests and lakes.

The pollution that passes directly into water from factories and cities can be reduced through treatment at source before it is discharged. It is harder to reduce the varied forms of pollution that are carried indirectly, by runoff, from a number of widely spread non-point sources, into the impact of human activity and the sea.Some of the major ways that demonstrate the impact of technology on the organization include the use of technological advancements. Antarctica is certainly the most pristine environment left on the earth.

Unfortunately this is no longer the case because of multiple human activities that have led to environmental issues and concerns such as pollution, ozone layer thinning, global warming analysis thesis. Human impact is a serious threat to ecosystem and food chain of Antarctica. In the last few decades, various marine species of Antarctic ecosystem have been brought close to extinction because of human activities in various forms such as pollution.

This essay is to outline the background of global warming and to display opposing viewpoints. Since there is not enough evidential research to connect global warming with natural factors, human activity, and its impacts, we might take advantage of its beneficial gain to our environment, economic, and social system.

The facts and fictions of global warming will convince members of Congress that there are opposing viewpoints to global warming and its effects. According to the Intergovernmental. Things look a little better for areas with the highest concentration of bird, mammal, and amphibian species, such as the Amazon Basin, which is still largely free from human impact.

However, the researchers the impact of human activity that footprint-free territory within these biodiverse areas has rapidly declined since These results suggest that the best conservation strategy may be to focus protection efforts on these species-rich areas and on remaining swaths of wilderness.

Read Caption. By Betsy Mason. These pools create a breeding ground for mosquitoes and other water-born insects. Malaria and other water-born diseases increase significantly whenever open pools of water are nearby. River dredging involves moving along a river on a platform or boat. The miners use a hydraulic suction hose and suction the gravel and mud as they move along the river. The gravel, mud, and rocks go through the tailings pipes and any gold fragments are collected on felt mats.

The remaining gravel, mud, and rocks go back into the river, but in a different location than where it was originally suctioned. This creates problems for the river. The displaced gravel and mud disrupt the natural flow of the river. Fish and other living organisms often die and fishermen can no longer navigate in the obstructed rivers. Mining is generally very destructive to the environment. It is one of the main causes of deforestation.

In order to mine, trees and vegetation are cleared and burned. With the ground completely bare, large scale mining operations use huge bulldozers and excavators to extract the metals and minerals from the soil. In order to amalgamate cluster the extractions, they use chemicals such as cyanide, mercury, or methyl mercury. These chemicals go through tailings pipes and are often discharged into rivers, streams, bays, and oceans.

This pollution contaminates all living organisms within the body of water and ultimately the people who depend on the fish for their main source of protein and their economic impact of human activity. The environmental damage caused by mining activities:. The topsoil as well as the vegetation are removed from the mining area to get access to the deposit. While large scale deforestation or de-vegetation leads abortion essay examples several ecological losses, the landscape also gets badly affected.

Huge quantities of debris and tailings along with big impact of human activities and disruptions spoil the aesthetic value of the region and make it prone to soil erosion. This is mainly associated with underground mining. Subsidence of mining areas often results in tilting of buildings, cracks in houses, buckling of roads, bending of rail tracks and leaking of gas from cracked pipe-lines leading to serious disasters.

Mining disturbs the natural hydrological processes and also pollutes the groundwater. Sulphur, usually present as an impurity in many ores is known to get converted into sulphuric acid through microbial action, thereby making the water acidic. Some heavy metals also get leached into the groundwater and contaminate it posing health hazards.

The acid mine drainage often contaminates the nearby streams and lakes. The acidic water is detrimental to many forms of aquatic life. Sometimes radioactive substances like uranium also contaminate the water bodies through uranium mine wastes and kill aquatic animals.

The impact of human activity

Heavy metal pollution of water bodies near the mining areas is a common feature causing health hazards. In order to separate and purify the metal from other impurities in the ore, smelting is done which emits enormous quantities of air pollutants damaging the vegetation nearby and has serious environmental health impacts. Most of the miners suffer from various respiratory and skin diseases due to constant exposure to the suspended particulate matter and toxic substances.

Miners working in different types of mines suffer from asbestosis, silicosis, black lung disease etc. Mining occurs in many places around the world, including the U. South Africa is also very well known for mining diamonds.

Mining also occurs in Indonesia and other S. Asian countries. The issue of transportation and the environment is paradoxical in nature. From one side, the impact of human activity activities support increasing mobility demands for passengers. On the other side, transport activities have resulted in growing levels of motorization and congestion. Further, the scope of the problem has grown significantly with economic growth in previously less developed nations such as China and India.

The effects of human activities vary with land use, ranging from agricultural wastes such as farm animal sewerage and fertilizer runoff, to commercial and industrial wastes of every conceivable type and magnitude. Over the years, the list of toxic contaminates has also grown, so that it not only includes heavy metals, radionuclides, and organic compounds of anthropogenic origin, but pharmaceuticals, explosives, and previously unknown biological pathogens.

The field of soil remediation has also grown tremendously over the past few decades. The goal of this special issue is to further explore the effects of human activities on soil contamination. Main article: Environmental impact of shipping. See also: Environmental impact of war.

Global Change Research Program. This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the midth century. For the warming over the last century, there is no convincing alternative explanation 4th grade essays examples by the extent of the observational evidence.

In addition to warming, many other aspects of global climate are changing, primarily in response to human activities. Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; diminishing snow cover; shrinking sea ice; rising sea levels; ocean acidification; and increasing atmospheric water vapor.

Researchers propose that unknown risks imply existential threats to the survival of humanity. Center for Biological Diversity. Human population growth has typically been seen as the primary causative factor of other ecologically destructive phenomena.

Current human disease epidemics are explored as 300 words essay function of population size. Here, human population growth is discussed as being subject to the same dynamic processes as the population growth of other species. Contrary to the widely held belief that food production must be increased to feed the growing population, experimental and correlational data indicate that human population growth varies as a function of food availability.

By increasing food production for humans, at the expense of other species, the biologically determined effect has been, and continues to be, an increase in the human population. Understanding the relationship between food increases and population increases is proposed as a necessary first step in addressing this global problem.
