Why is the term climate change used than global warming?

Global warming causes climate change. We now use the term climate change because it deals with all the many changes. Global warming is still happening and the warming is putting more energy into the atmosphere. This extra energy is changing the climate.

Does wood burning contribute to air pollution?

A very simple question sometimes does not lead to a simple answer. But, in general yes, similar in chemical composition, dissimilarities in pollution threat levels. A "pollutant" does harm to natural processes. Both burning of wood and fossil fuels generate carbon dioxide, and excess CO2 in our atmosphere contributes to global warming. See http://en.wikipedia.org/wiki/Wood_fuel Wood burning creates particulate air pollution can contribute to human health problems and increased hospital admissions for asthma & heart diseases. Wood burning smoke pollutants include nitrogen oxide, sulfur dioxide, volatile organics, radioactive compounds, carbon monoxide, formaldehyde and suspect carcinogens (polycyclic aromatics and dioxins), See: http://www.lungusa.org/site/c.dvLUK9O0E/b.23354/k.100/Woodburning.htm According to the American Lung Association, oil or natural gas generate less pollutants in the home per btu, than wood. They also recommend on their website how to make wood burning safer. The fossil fuels are generally considered coal, oil and natural gas. See: http://en.wikipedia.org/wiki/Fossil_fuel The list of pollutants are similar to wood burning, CO2, nitrogen oxide and sulfur dioxide. Harmful volatile organics and radioactive compounds (uranium and thorium) are also produced as with wood burning. The pollution threat can not just be measured in what these energy sources produce, but how much they produce. Again, refer to Wikipedia under fossil fuels, and you will see that a steep increase in released emission of carbon to the atmosphere beginning in 1950 from fossil fuel combustion.

What pollutants are released from power stations?

The answer is depending on what fuel power plant use and their waste treatment system.

Coal fire would yield CO2, SOx, NOx, dust particulates and Slack. SOx can be treated using scrubber. Particulates and NOx can be prevent using correct Air-Fuel ratio and trapped out using scrubber.

Gas Fire would yield every pollution like Coal except in lower amount of SOx and without Slack.

Hydro power may not yield any pollutants at all.

Temperature can be considered a pollution if it cause ecological damage. Power plant may cause water pollution if they discharge hot water without pre-cool. Same amount of water and temperature may not be considered a pollutant if the river stream is large enough.

What are the causes of environmental Pollution in India?

The causes of environmental pollution in India include industrial emissions, agricultural practices like excessive use of pesticides and fertilizers, vehicle emissions, improper waste management, and deforestation. Rapid urbanization and population growth also contribute to air, water, and soil pollution in the country.

What is the principal source of air pollution from volcanoes?

The principal source of air pollution from volcanoes is sulfur dioxide (SO2) emissions. When a volcano erupts, it releases large amounts of sulfur dioxide into the atmosphere, which can react with sunlight, water, oxygen, and other chemicals to form sulfuric acid aerosols, which contribute to air pollution.

What can be cone to reduce river pollution?

To reduce river pollution, measures such as implementing stricter regulations on industrial discharge, improving sewage treatment plants, promoting sustainable farming practices to reduce runoff, and increasing public awareness about proper waste disposal can be taken. Collaborative efforts involving governments, industries, and communities are essential to effectively address and mitigate river pollution.

What is good pollution?

Pollution itself is a word with negative connotation meaning to dirty the environment so there is no such thing as "good pollution".

However it can be used as in an ironic sense that you are going to pollute with a good thing. Let's say you pollute with something like music, if you play music (that nobody disagrees to) then you are spreading something into the area that isn't harmful, but rather pleasant. But the way it is spreading is like pollution, a form of parallelism of the spreading of both waste pollution and this "good pollution" making it ironic because pollution is bad, but you're spreading a good thing!

What percentage of clean technologies have enabled humans to reduce air pollution?

Approximately 70-80% of clean technologies have contributed to reducing air pollution by improving energy efficiency, reducing emissions from transportation, and promoting renewable energy sources like solar and wind power. These technologies focus on minimizing harmful pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides that contribute to air pollution.

What is its hydronium concentration of acid rain at pH of 3.0?

pH=-log[H+]. 3= -log[H+] Antilog is equal to H+ concentration.So it is equal to 10^-3.

What kinds of control equipment are there?

There are various types of "control", therefore, there are various types of control equipment. There is birth control equipment, livestock control equipment, air pollution control equipment, etc.

What pollution is it called when a man washes clothes in a stream using a detergent that contains phosphorus?

the answer is actually nutrient pollution because it says what "POLLUTION" is whatever so the answer would be nutrient pollution because if you read the question you can break it up into some words so the word "pollution" is telling you it has something to do with pollution so therefore the answer is:

Answer: Nutrient Pollution

What are major factors in river pollution?

The Oregon Department of Environmental Quality (ODEQ) has established water quality standards to protect these beneficial uses. The standards, based on supporting the various beneficial uses, determine the acceptable levels or ranges for water quality parameters, including temperature, dissolved oxygen, and pH. Water quality standards set by ODEQ are reviewed and updated every three years. ODEQ and others monitor water quality parameters in streams and other waterbodies throughout Oregon. Waterbodies that are not within the standards are listed as "water quality impaired." The list of impaired streams is called the "303(d) list," after section 303(d) of the 1972 Clean Water Act. # 303D streams in Umpqua Basin and # in entire state.

How can breeding programmes reduce the amount of pollution?

Using breeding programs develops plants with different genetic traits that can help reduce pollution. One instance of this is plants that need less fertilizer reduce the amount of nitrogen getting into water.

Is air pollution only caused by human activity?

While human activities like industrial processes, vehicle emissions, and deforestation are significant contributors to air pollution, natural sources such as wildfires, volcanic eruptions, and dust storms also release pollutants into the air. These natural sources can have localized or temporary impacts on air quality.

How can living and non living indicators can measure levels if pollution?

A living indicator of pollution would be organisms dying or getting sick from the pollutants. A non-living indicator could be a high amount of smog or other pollutants in the air or on buildings.

Which indian leader said that poverty is the root cause of pollution?

Former Indian Prime Minister, Indira Gandhi, said, "Poverty is the worst form of pollution." This emphasizes the link between poverty and environmental degradation, highlighting the importance of addressing poverty in order to tackle pollution effectively.

Why does it take a long time for polluted groundwater to become pure again?

Polluted groundwater takes a long time to become pure again because the contaminants need to naturally degrade or be filtered out by soil and rocks as the water moves through the ground. Additionally, the size of the aquifer, the type of contaminant, and the depth of the pollution can all affect the timeframe for purification. Treatment methods may also be needed to speed up the process.

How can breeding programs reduce pollution?

Breeding programs can reduce pollution by creating breeds of animals that are more efficient in converting feed into produce, thereby reducing the overall amount of feed required and lowering the associated pollution from feed production. Additionally, breeds can be selected for traits that produce less waste or have lower environmental impacts, leading to reduced pollution levels from animal agriculture. Lastly, breeding programs can focus on developing animals that are more resistant to diseases or environmental stressors, which can reduce the need for pharmaceutical interventions that contribute to pollution.

Which nations have a cap and trade or carbon tax system in place?

The following nations have a carbon trading system in place, or are committed to implementing one:

  • The member countries of the European Union
  • New Zealand
  • Some states of the United States of America

    - a federal scheme was blocked in the Senate in 2009

  • Some provinces of Canada
  • Japan - to a limited extent

China has committed to implementing a carbon price in 2011.

The Australian government has committed to implementing a carbon tax, to be replaced in due course by a carbon trading scheme, but as at April 2011 has not yet legislated for this.

Why do governments not fix industrial pollution of rivers and water ways?

government cannot fix industrial pollution of rivers and waterways, because the nation is under debt threats now, and also most of the pollution is fixed by the rivers are fixed by themselves. also there are filters that filters the water we use before we use it. right now the only thing the government can do is make the industries clean their wasteor to make thempay for it.

Can factories and power plants release toxins pollution in limited amounts legally?

Yes, factories and power plants can release toxins and pollution legally, as long as they comply with regulations set by environmental protection agencies. This includes obtaining permits, monitoring emissions, and meeting established pollution control standards to minimize the impact on the environment and public health.

What effect does plastic utenstills pollution have on humans?

AnswerIn this era of many astonishing industrial developments, probably no industry has under gone such rapid growth and development as the plastics industry. According to most authorities in this field, the plastics industry really began in 1868. A young American printer, named John Wesley Hyatt, was searching for a new material to be used as a substitute for ivory in the making of billiard balls.

This new plastic was called Bakelite. Many new plastics have been made since Bakelite. Production of plastics has increased over 2000% since Bakelite was first produced, and there are now more than twenty known types. Research along the lines of plastics has given a great impetus to research and invention in many other different fields of endeavor. Millions of dollars are spent yearly in plastics research, trying to find new plastics and to improve the existing ones. Much research will be done in the future to lower the cost of producing plastics so that their consumption will become greater. In spite of the varied and widespread application of plastics in practically every phase of everyday life, the possibilities of this wonderful new material have been by no means exhausted. It seems safe to say that if the application and use of plastics continue to increase at the present rate, we may be living in a "Plastics Age."

An apt definition of plastics has been given by the head of the Monsanto Plastics Research who says, "Plastics are materials that, while being processed, can be pushed into almost any desired shape and then retain that shape."

The major chemicals used to make plastic resins pose serious risks to public health and safety. Many of the chemicals used in large volumes to produce plastics are highly toxic.Some chemicals, like benzene and vinyl chloride, are known to cause cancer in humans; many tend to be gases and liquid hydrocarbons, which readily vaporize and pollute the air. Many are flammable and explosive. Even the plastic resins themselves are flammable and have contributed to numerous chemical accidents. The production of plastic emits substantial amounts of toxic chemicals(eg. ethylene oxide, benzene and xylenes) to air and water. Many of the toxic chemicals released in plastic production can cause cancer and birth defects and damage the nervous system, blood, kidneys and immune systems. These chemicals can also cause serious damage to ecosystems.

Ethylene oxide is used as a sterilant in hospitals. It is also the principle metabolite of ethene, a precursor to polyethylene plastics and other synthetic chemicals. Ethylene oxide can be measured by gas chromatography in air or biological specimens. Ethylene oxide reacts in the body with hemoglobin.

Many food containers for meats, fish, cheeses, yogurt, foam and clear clamshell containers, foam and rigid plates, clear bakery containers, packaging "peanuts," foam packaging, audio cassette housings, CD cases, disposable cutlery, and more are made of polystyrene. J. R. Withey in Environmental Health Perspectives 1976 Investigated styrene and vinyl chloride monomer as being similar: "Styrene monomer readily migrates from food contained in it. It makes no difference whether the food or drink is hot or cold, or contains fat or water. ...It is not inconceivable that the animal body behaves as a 'sink' for styrene monomer until the lipid portion of the animal body either becomes saturated (although death would probably occur prior to this event) or the tissues are equilibrated at the same concentration as the exposure atmosphere."

PVC is used for many products including: flooring, toys, teethers, clothing, raincoats, shoes, building products like windows, siding and roofing, hospital blood bags, IV bags and other medical devices. One of it's major ingredients is chlorine. When chlorine-based chemicals are heated in the presence of hydrocarbons they create dioxin, a known carcinogen and endocrine disruptor. All PVC production releases dioxin. Other sources of dioxin are: production and use of chemicals, such as herbicides and wood preservatives, oil refining, burning coal and oil for energy, all car and truck exhaust, cigarette

Plasticizers are used in PVC that migrate into a blood recipient via the blood bag, IV bag, IV tubing. Children's toys are made with pvc.

Anyone who receives blood, is on kidney dialysis, or has tubes either inserted in them or has liquid or air transported to their body is at risk. About 85% of medical waste is incinerated, accounting for ten percent of all incineration in the U.S.Approximately five to fifteen percent of medical waste needs to be incinerated to prevent infectious disease. The remaining waste, while not posing any danger from infectious pathogens, is very dangerous when burned. It contains high volumes of chlorinated plastics including PVC (also the toxic substances mercury, arsenic, cadmium and lead.

What is the largest human impact on forest ecosystems?

Deforestation is considered one of the largest human impacts on forest ecosystems. It involves the clearing of trees on a large scale for agriculture, urban development, logging, and other human activities, leading to habitat loss, disruption of biodiversity, and altering of the ecosystem functions. This can have severe consequences for the environment, including loss of wildlife, disruption of water cycles, and increased carbon emissions.

Which of these is not an effect of severe overpopulation?

Severe overpopulation can lead to strain on resources, increased poverty, and reduced quality of life. However, an effect that is not associated with severe overpopulation is reduced biodiversity, as overpopulation does not directly impact the variety of species in an area.
