100 Points Given for Answer

Answer 1

1) Air pollution

Air pollution is a result of industrial and certain domestic activity. An ever increasing use of fossil fuels in power plants, industries, transportation, mining, construction of buildings, stone quarries has led to air pollution.

Main causes of air pollution

Particulate pollutants

Particulate matter suspended in air are dust and soot released from the industrial chimneys. Their size ranges from 0.001 to 500 µm in diameter. Particles less than 10µm float and move freely with the air current. Particles which are more than 10µm in diameter settle down. Particles less than 0.02 µm form persisent aerosols. Major source of SPM (suspended particulate matter) are vehicles, power plants, construction activities, oil refinery, railway yard, market place, industries, etc.

Water pollution

Water pollution is one of the most serious environmental problems. Water pollution is caused by a variety of human activities such as industrial, agricultural and domestic. Agricultural run-off laden with excess fertilizers and pesticides, industrial effluents with toxic substances and sewage water with human and animal wastes pollute our water thoroughly. Natural sources of pollution of water are soil erosion, leaching of minerals from rocks and decaying of organic matter. Rivers, lakes, seas, oceans, estuaries and ground water sources may be polluted by point or non-point sources.

Main causes of water pollution

Pesticides like DDT and others used in agriculture may contaminate water bodies. Aquatic organisms take up pesticides from water get into the food chain (aquatic in this case) and move up the food chain. At higher trophic level they get concentrated and may reach the upper end of the food chain.



2) The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities..

3) Benefits of Renewable Energy

Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.

Disadvantages of Renewable Energy
Renewable Energy Is Not Available Round the Clock. ...
The Efficiency of Renewable Technologies Is Low. ...
The Initial Cost of Renewable Energy Is High.

4) Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization.

5) recycling = build an eco brick
reusing = reuse plastic bags
reduce. = close the water while brushing your teeth.

Answer 2

answer 1:

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light

Air Pollution

Water Pollution

Soil pollution

Noise pollution

Radioactive pollution

Light pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil

Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

Effects:

Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.

answer 2:

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

anwer 3:

advantages are

1_A Fuel Supply That Never Runs Out

2_Zero Carbon Emissions

3_Cleaner Air and Water

4_A Cheaper Form of Electricity

5_Renewable Energy Creates New Jobs

disadvantages are

1_Higher Capital Costs

2_Electricity Production Can Be Unreliable

3_Energy Storage Is a Challenge

4_It’s Impacted by Environmental Conditions

5_Renewables Still Have a Carbon Footprint

anwer 4:

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.

answer 5:

You could do this by:

1_Try to stay away from disposable goods. In particular, paper plates, cups, bottles, and plastic utensils.

2_Buy durable and reusable goods. ...

3_Pack your lunch in a reusable box rather than foil or cling film.

4_Buying products with less packaging. ...

5_Buying products in bulk.

I WISH THIS WILL BE HELPFUL, GOOD LUCK :)
