How does pollution affect the world?

Answer 1

Water pollution is the addition of harmful materials to a body of water in concentrations that affect its quality. Water pollution kills life that lives in water. Water pollution also affects the food chain when smaller organisms eat it and are than eaten by larger ones eventually humans come into the food chain too. People can get hepatitis by eating poisoned seafood. Plants are also affected by water pollution. As people dump chemicals into the water the plants there are affected by it. The chemicals work as a fertilizer by making the plants grow as they grow they need more and more oxygen that they used to share with other organisms that lived there. As the plants die from their lack of water they have to decompose which uses even more oxygen, which the fish and other organisms need to survive. This causes the whole ecosystem to be unbalanced.

Answer 2

SO, CO2 and Methane both contribute to the green house effect, creating a blanket around the earth that traps the suns heat, causing global warming and climate change. Also there is sulphur dioxide and nitrous oxides which dissolve with rain droplets to form weak acids which fall as acid rain damaging buildings and killing aquatic life.

Hope that's OK...

Answer 3

It can cause medical respiratory problems, and also affects the quality of life in the area and has been shown to have a non-causational link with house prices. It will also cause cancer in most people.

Answer 4

Air pollution has many affects. If it is in the form of gases in the atmosphere, it can cause global warming and Ozone Layer depletion. These gases can also condense within clouds and pollute the rain that falls, subsequently polluting the water and land that the rain falls onto. Also, air pollution can be very harmful if breathed in by humans. While there are many different levels of how severe the air pollution is and different people have varrying levels of sensitivity, but an alright AQ

I (Air Quality Index) can cause irritation in sensitive people, like those with Asthma or breathing problems. A bad AQU can cause lung problems in all people, and can be deadly if left for too long or if breathed in too much. Bad and polluted air can kill off animals that depend on fresh oxygen, like fish and microorganisms, and can also harm plant life and vegetation.

Answer 5

The air we breathe day in and day out has a significant impact on our health, especially for those with asthma and other types of lung or Heart disease.1 And while air quality in many cities in North America and Europe has improved significantly over the last two decades, many cities in both developed and emerging economies continue to have air pollution problems from the effects of burning fossil fuels.2 As economies and urban center populations continue to grow, the air quality challenge will grow as well. The combustion of fossil fuels for power generation and transport has been a significant contributor to urban air pollution, acid rain and smog; burning fossil fuels emits sulfur dioxide (SO2) and nitrogen oxides (NOx), unless these are "scrubbed out" of stack gas. That's changing for the better in many places: in transportation, reductions in emissions of pollutants can be achieved through the use of low sulfur fuels and other clean fuels; in electricity generation, gas-fired power plants and coal gasification are approaches that produce less air pollution than conventional coal plants.3 While switching to renewable energy often sounds like a solution to air pollution challenges, there are significant scientific and commercial challenges that will need to be resolved through the work of a broad array of business, government, and other stakeholders to make alternatives a viable choice for large scale deployment.4 Meanwhile, technology, regulation, and consumer choices can all play a role in reducing the impact of our energy use on the air we breathe. Air quality regulations such as the federal Clean Air Act in the United States have led to significant progress over the last twenty years. Additionally, new industrial facilities and power plants are being designed with innovative technology that creates substantially fewer pollutants than facilities with older technology. Further progress is also being made with the spread of low sulfur fuels as energy inputs, which are less polluting.5 Multi-stakeholder initiatives are bringing together donors, government agencies, and businesses to work on solutions for urban air pollution in mega-cities. Such partnerships include the Clean Air Initiative for Asian Cities (CAI-Asia), which was launched by the Asian Development Bank together with the World Bank and the US Agency for International Development as well as the Clean Air Institute which manages the Clean Air Initiative for Latin American Cities.6 Technology, regulation, and consumer choices can all play a role in reducing the impact of energy use on the air we breathe. Like many other environmental issues related to energy, air pollution can be reduced through energy efficiency and conservation improvements, both at the consumer and industry level.

Answer 6

it hurts it!!

well, yes it hurts the environment but it causes plants and animals to die.

Answer 7

Air pollution does a lot of damage. It also depletes ozone.

Answer 8

All sorts
