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.

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. ...
