The air pollutants also cause diseases in humans like lung cancer, asthma, pollution Irritation of eyes, nose, mouth and throat, disruption of endocrine, reproductive and immune systems and other respiratory ailments. Water Pollution- Its effects are as follows:-i. Water bodies like lakes and rivers are polluted which results in the death Fishes die dueanimals like of marine to water Typhoid pollution fishes, turtles, whales, dolphins etc. Oil spills not only harm marine animals but they also affect precipitation rate. If the polluted water is consumed by humans then water-borne diseases like typhoid, cholera, shes due to death of a oil spill affected Duck eutrophicationiv. When the pesticides after surface runoff reach Athe lakes, they lead to the growth of algae which child who died due to after sometime covers the whole lake and due consumption of polluted to lack of oxygen the animals die. Soil Pollution- Its effects are:- cows die by eatingi. The waste from landfill leaches and causes plastic bags contaminates the groundwater.

These acids are formed primarily by nitrogen oxides and sulfur oxides Acid rain released into the atmosphere when fossil fuels are burned. Haze is caused hamburger when sunlight encounters tiny pollution particles in the air. Haze asthma can be caused obscures the clarity, color, texture, and form of what we see. Toxic pollutants in the air, or deposited on soils or surface waters, can impact wildlife in a number of ways. Like humans, animals can experience health problems if they are exposed to sufficient concentrations of air toxics over time. Respiratory problems, reduced lung functioning are certain problems which can occur in the people. Ozone depletion- This is a layer present in the atmosphere which protects us haze from the harmful ultraviolet rays of the sun which can cause skin cancer. But due to the air pollutants this layer is getting depleted. These gases also cause the Green house effect and Global warming. Heath effects of airvi.
Soil pollutionsoil contamination or soil pollution is caused by the presenceof xenobiotic (human-made) chemicals or other alteration inthe natural soil environment. It is typically caused by industrialactivity, agricultural chemicals, or improper disposal of e most common chemicals involved arepetroleum hydrocarbons, polynuclear aromatic hydrocarbons(such as naphthalene and golf lead, and other heavy metals. Contamination iscorrelated with the degree of industrialization and intensity ofchemical usage. Soil contamination can be caused by:Corrosion of underground storagetanks (including piping used to transmit thecontents)Application of pesticides and fertilizersMiningOil and fuel dumpingDisposal of coal ashLeaching from landfillsDirect discharge of industrial wastes to the soilDrainage of contaminated surface water into thesoil. Mining coal pollutes the environmentCoal Ash pollutes the forests. Air Pollution- air pollution has serious effects on environment as well as human health. Acid rain is precipitation containing harmful Greenhouse Effectsulfuric amounts of nitric and acids.
The main sources of water pollution are-. Effluent outfalls from factories, refineries, waste treatment plants etc. That emit fluids of varying quality directly into urban water supplies. In villages people have baths in the river, they wash their clothes and utensils there because of which the river water gets polluted. In holy rivers like ganga people have baths. They also immerse the dead bodies in the river because of which the water gets severely polluted. In cities the people throw food wrappers paper and other wastes in the water bodies which pollutes thedeep Water Horizon Oil Spill the reason why mumbais Mithi river is water. This is very polluted. Villagers having pollution in river bath of rivers by citiesganga pollution mumbais mithi river.

Environmental Pollution Definition Of Environmental Pollution:Environmental pollution is the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected. Types Of Environmental PollutionThere are three major types of environmental pollution:Air pollutionWater pollutionSoil pollution (contamination) air pollution pollution water soil pollution pollution. Air pollutionair pollution is the introduction intothe atmosphere of chemicals, particulate matter,or biological materials that cause discomfort, disease,or death to humans, damage other living organismssuch as food crops, or damage the natural environmentor built environment. Smoke from chimneys, automobile exhaust, burning offossil fuels and forest fires result in air pollution. Some of the most important air pollutants are sulfurdioxide, nitrogen dioxide, carbon monoxide, ozone, volatile organic compounds (VOCs) and airborneparticles, with radioactive pollutants probably amongthe most destructive ones (specifically when producedby nuclear explosions).due to increase in the volume of these gases inatmosphere the ozone layer. Water pollutionwater pollution is the contamination of water bodies(e.g. Lakes, rivers, oceans, aquifers and groundwater). Waterpollution occurs when pollutants are discharged directly orindirectly into water bodies without adequate treatment toremove harmful compounds.

Links between resource efficiency and climate change emissions of greenhouse gases from manufacturing, agriculture, transport, forestry, aviation, shipping Embodied energy total sum of energy to produce emissions from waste transport energy use transfer of greenhouse gases from one part of a cycle to another. Hybrid cars reduce fuel consumption but use inefficient coal fired power stations to charge batteries. Business reasons for Resource Efficiency regulation and legislation Reputation Cost reduction Staff retention Profitability development of industrial capability Standard of living in less developed countries. Reduce, reuse, recycle In order to minimise the impact of waste products on the environment there are actions that we can take by reducing what we use, reusing products and recycling waste.

In 160 years of records the revelation hottest years have been since 1997. Group Exercises Identify the following; Commonly used resources how resource efficiency affects climate change reasons why a business should be general resource efficient group task. Commonly used resources renewable non-renewable can be replenished through biological or natural processes solar wind tides hydro power biomass (plants, trees etc, when harvested sustainably) food stuffs cannot be grown, replenished in the same rate it is consumed Fossil fuels coal gas oil (fuel, petrol. A few facts we throw away more than 7 million tonnes of food and drink every year from our homes most of which could have been safely consumed. by pursuing opportunities for re-use, the uk could reduce its reliance on raw materials, including rare earths, by as much as 20 by 2020. our research shows doubling the number of sofas re-used, could save 52,000 tonnes of CO2 equivalent. At the moment, 83 of sofas are not re-used and are sent to landfill or recycled.
CO2 Emissions Agriculture fluorinated gases (CFCs, hfcs) waste industry transport Industry household. Impacts of Environmental change major Impacts: Global warming sea level rise Ocean acidification health Temperature rise Extreme weather events Deforestation Ecosystem strain Loss of biodiversity. Global Warming The main cause of global warming is the emission of greenhouse gases such as carbon dioxide, methane and nitrous oxide. human activity over the past 250 years, including the burning of fossil fuels, change of land use and agriculture, has increased the concentration of greenhouse gases in the earths atmosphere. As these gases build up in the atmosphere they strengthen what is known as the greenhouse effect. Global Warming there has been a clear decreasing trend in Arctic summer sea ice levels since records began in 1979. Sea level around the uk rose by 10cm during the 20th century. The earths surface has warmed.4 c on average since the 1970s, 1 c in last 100 years.
