Humans said have huge impact on erosion

Global Sensitivity and Uncertainty Analysis in the Evaluation of Social-Ecological Resilience: Theoretical Debates Over Infrastructure Impacts on Livelihoods and Forest Change Stephen Perz, University of Florida Scientists will use a systems approach that features resilience as a concept to bring together economic, ecological and social science perspectives to better understand infrastructure impacts. They will study the Southwestern Amazon, a region with high biodiversity and in which highway-paving is underway. A Global Sustainable Soundscape Network Bryan Pijanowski, Purdue University Scientists will organize a research coordination network on "soundscapes" to facilitate interaction among ecologists, cognitive psychologists and scholars in the humanities, as well as those from other fields, to explore perspectives on human and natural system interactions.

Soundscapes, the cacophony of sounds in the environment, play important roles in ecosystems. Diversification, Portfolio Effects, and the Sustainability of Fishing Communities Daniel Schindler, University of Washington Researchers will investigate how the biocomplexity of fisheries ecosystems translates into social and economic attributes in the human communities that exploit these ecosystems.

The scientistsn will examine salmon ecosystems and the social and economic benefits to people who rely on salmon for their livelihoods in Western Alaska. Long-Term Vulnerability and Resilience of Coupled Human-Natural Ecosystems to Fire Regime and Climate Changes at an Ancient Wildland Urban Interface Thomas Swetnam, University of Arizona Scientists will test alternative hypotheses about how human activities at the wildland-urban interface affect the response of fire-adapted pine forests to climate change and how humans respond to these changes over centuries by combining archaeological and paleoecological evidence.

The evidence is from an ancient wildland-urban interface in Northern New Mexico, where large communities of Native American farmers lived in ponderosa pine forests through varying climate episodes over the last 1, years. Impacts of Global Change Scenarios on Ecosystem Services from the World's Rivers Charles Vorosmarty, CUNY-City College Researchers will look at the ways in which humans control, degrade or enhance water-related "ecosystem services," quantifying their effects on the global economic system and on aquatic biodiversity, projecting these relationships into the future and assessing how alternative management strategies can lead to more sustainable futures over a year time horizon.

The tropical common coqui frog sings; "soundscapes" are the subject of a CNH project. Water resource management and local governance are the focus of a CNH award. Highways affect the southwestern Amazon region; CNH scientists will find out how much. The National Science Foundation NSF is an independent federal agency that supports fundamental research and education across all fields of science and engineering.

NSF funds reach all 50 states through grants to nearly 2, colleges, universities and other institutions. Humans are now so numerous and resource-dependent that their activities affect every part of the environment, from outer space and the stratosphere to the deepest ocean. However, by using science-based predictive models, humans can anticipate long-term change more effectively than ever before and plan accordingly. For example, there are historical records of weather conditions and of the times when plants bloom, animals give birth or migrate, and lakes and rivers freeze and thaw.

And scientists can deduce long-past climate conditions from such sources as fossils, pollen grains found in sediments, and isotope ratios in samples of ancient materials. Engineering advances have led to important discoveries in virtually every field of science. These discoveries have in turn increased the need for more sophisticated technologies to solve even more complex science problems. Scientific development has lead to the development of entire industries and engineered systems. Influence of Engineering, Technology, and Science on society and the natural world.

Human impact on the environment - Wikipedia

All human activity draws on natural resources and has both short-term and long-term consequences, which can be positive as well as negative for the health of both people and the natural environment. The uses of technology and amy limitations on their uses are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate , natural resources, and economic conditions. Skip to main content. A Earth Materials and Systems: How do the major earth systems interact?

B Natural Hazards: How do natural hazards affect individuals and societies? While a wind farm may cover a large area of land, many land uses such as agriculture are compatible, with only small areas of turbine foundations and infrastructure made unavailable for use. There are reports of bird and bat mortality at wind turbines, as there are around other artificial structures. The scale of the ecological impact may [94] or may not [95] be significant, depending on specific circumstances. Prevention and mitigation of wildlife fatalities, and protection of peat bogs , [96] affect the siting and operation of wind turbines.

There are conflicting reports about the effects of noise on people who live very close to a wind turbine. Artificial light at night is one of the most obvious physical changes that humans have made to the biosphere, and is the easiest form of pollution to observe from space.

10 Ways Humans Impact the Environment

The hunting efficiency of visual predators generally increases under artificial light, changing predator prey interactions. Artificial light also affects dispersal , orientation, migration , and hormone levels, resulting in disrupted circadian rhythms. A study from the researchers at Imperial College London sheds light on the damage tobacco cultivation and smoking inflicts on the environment. The study outlines how the six trillion cigarettes produced and discarded annually greatly exacerbate climate change. Every part of the tobacco sector harms the environment, from the huge amount of firewood needed to cure tobacco leaves to non-biodegradable butts that leak poisonous chemicals into water tables, soil and the food chain.

The environmental impact of cleaning agents is diverse. In recent years, measures have been taken to reduce these effects. Nanotechnology 's environmental impact can be split into two aspects: the potential for nanotechnological innovations to help improve the environment, and the possibly novel type of pollution that nanotechnological materials might cause if released into the environment.

As nanotechnology is an emerging field, there is great debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems. The environmental impact of paint is diverse. Traditional painting materials and processes can have harmful effects on the environment , including those from the use of lead and other additives. Measures can be taken to reduce environmental impact, including accurately estimating paint quantities so that wastage is minimized, use of paints, coatings, painting accessories and techniques that are environmentally preferred.

Learning Outcomes for Study Session 1

The environmental impact of paper is significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. Some scientists suggest that by there could be more plastic than fish in the oceans.

The environmental impact of pesticides is often greater than what is intended by those who use them. The amount of pesticide that migrates from the intended application area is influenced by the particular chemical's properties: its propensity for binding to soil, its vapor pressure , its water solubility , and its resistance to being broken down over time. The environmental impact of pharmaceuticals and personal care products PPCPs is largely speculative. PPCPs are substances used by individuals for personal health or cosmetic reasons and the products used by agribusiness to boost growth or health of livestock. PPCPs have been detected in water bodies throughout the world. The effects of these chemicals on humans and the environment are not yet known, but to date there is no scientific evidence that they affect human health.

The environmental impact of mining includes erosion , formation of sinkholes , loss of biodiversity , and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Some mining methods may have significant environmental and public health effects.

The environmental impact of transport is significant because it is a major user of energy , and burns most of the world's petroleum.

This creates air pollution , including nitrous oxides and particulates , and is a significant contributor to global warming through emission of carbon dioxide , [] for which transport is the fastest-growing emission sector. Environmental regulations in developed countries have reduced the individual vehicles emission; however, this has been offset by an increase in the number of vehicles, and more use of each vehicle.

Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl , which can consume natural habitat and agricultural lands. By reducing transportation emissions globally, it is predicted that there will be significant positive effects on Earth's air quality , acid rain , smog and climate change.

The health impact of transport emissions is also of concern.

A recent survey of the studies on the effect of traffic emissions on pregnancy outcomes has linked exposure to emissions to adverse effects on gestational duration and possibly also intrauterine growth. The environmental impact of aviation occurs because aircraft engines emit noise , particulates, and gases which contribute to climate change [] [] and global dimming.

There is an ongoing debate about possible taxation of air travel and the inclusion of aviation in an emissions trading scheme, with a view to ensuring that the total external costs of aviation are taken into account. The design, construction and management of roads , parking and other related facilities as well as the design and regulation of vehicles can change the impacts to varying degrees.

The environmental impact of shipping includes greenhouse gas emissions and oil pollution. It was tasked with developing the technical basis for the reduction mechanisms that may form part of a future IMO regime to control greenhouse gas emissions from international shipping, and a draft of the actual reduction mechanisms themselves, for further consideration by IMO's Marine Environment Protection Committee MEPC.

General military spending and military activities have marked environmental effects. The military does not solely have negative effects on the environment. As well as the cost to human life and society, there is a significant environmental impact of war. Scorched earth methods during, or after war have been in use for much of recorded history but with modern technology war can cause a far greater devastation on the environment. Unexploded ordnance can render land unusable for further use or make access across it dangerous or fatal.


Human activity is causing environmental degradation , which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction ; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. Biodiversity generally refers to the variety and variability of life on Earth, and is represented by the number of different species there are on the planet. Since its introduction, Homo sapiens the human species has been killing off entire species either directly such as through hunting or indirectly such as by destroying habitats , causing the extinction of species at an alarming rate.

Humans are the cause of the current mass extinction , called the Holocene extinction , driving extinctions to to times the normal background rate. Human overpopulation and continued population growth along with profligate consumption are considered to be the primary drivers of this rapid decline. Defaunation is the loss of animals from ecological communities.

It is estimated that more than 50 percent of all wildlife has been lost in the last 40 years. Because of human overpopulation, coral reefs are dying around the world. Coral reefs also face high dangers from pollution, diseases, destructive fishing practices and warming oceans. The list of factors is long, including the ocean's role as a carbon dioxide sink , atmospheric changes, ultraviolet light , ocean acidification , biological virus , impacts of dust storms carrying agents to far flung reefs, pollutants, algal blooms and others.

Reefs are threatened well beyond coastal areas.
