What are the effects of water pollution on environment?
Harm to any of these organisms can create a chain effect, imperiling entire aquatic environments. When water pollution causes an algal bloom in a lake or marine environment, the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water.
What are some examples of natural air pollution?
Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.
What are the causes and effects of air pollution?
Also, sulfur dioxide is emitted from the vehicles burning petrol and coal cause harmful respiratory diseases like kidney failure, lung cancer and various other heart-related diseases. Smoke emitted from aeroplanes too is one of the major causes of air pollution.
What is the conclusion for air pollution?
The health of the public, especially those who are the most vulnerable, such as children, the elderly and the sick, is at risk from air pollution, but it is difficult to say how large the risk is.
How is air pollution harmful to the environment?
Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).
What is the result of air pollution?
The combined effects of ambient (outdoor) and household air pollution cause about seven million premature deaths every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.
How do we stop air pollution?
Ways to Reduce Air Pollution
- Riding a bike or walking instead of driving.
- Taking a bus or carpooling.
- Buying a car that has greater fuel efficiency.
- Turning off lights and appliances when they are not in use.
- Using energy efficient light bulbs and appliances.
- Buying fewer things that are manufactured using fossil fuels.
What are the main problems of air pollution?
Common air pollution issues are discussed below.
- 1.1 Acid Rain. The term “Acid rain” is commonly used to refer the wet (fog, rain, cloud water, snow, sleet, and dew) and dry (acidifying gases and particles) deposition of acidic components.
- 1.2 Global Warming and Climate Change.
- 1.3 Ozone Layer Depletion.
How does air pollution affect humans?
The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. Microscopic pollutants in the air can slip past our body’s defences, penetrating deep into our respiratory and circulatory system, damaging our lungs, heart and brain.
