The source of noise pollution is loud/noisy sound sources. An example is from a factory, where there are engines, vibrations, and air movement of gases and liquids. Others such as loud concerts, speakers, or even just a motorcycle passing you at high speeds. There are also natural sources such as volcanic eruptions, earthquakes, meteors fly-by, etc.
The consequences of noise pollution are as follows.
Living things in a polluted environment, both humans and animals will be disturbed by the irritating loud noise. Sounds that are too loud can result in damage, irritation, or even loss of one's hearing. According to research, sounds that reach above 70db played for a long period can damage one's hearing.
There are a few solutions we can do to prevent noise pollution. First, we can adjust the volume of our sound sources (eg. our music, our voice) to a one that is proportional and comfortable to hear. Secondly, we can definitely ask our neighbors to lower their volume, if they get too disturbing.
Thirdly, while this is a hard thing, (especially during the pandemic), we can spread the news about noise pollution, and how it is bad for humanity and animals alike.
    Secondly, we have Air Pollution
I'm sure you heard of the scenario named "fog" where a certain part of a location is covered in dust, ash, smoke, etc. Fogs are normally caused by air pollution.
Air pollution is when air quality becomes damaged and contaminated. There are two types of causes of air pollution, namely Primary and Secondary. Primary is when pollution is caused directly by the pollutant source, and secondary is when the reaction between primary substances in the atmosphere. An example of primary pollution is an increase in CO2. Example of secondary formation of Ozone.
The cause of air pollution is pollutant substances that pollute or poison the air. Some examples of these substances are Carbon Monoxide, Nitrogen Dioxide (NO2), and Sulfur Oxide (SOx).
There are several consequences of air pollution such as acid rain (pH of rain decreases to acid), the greenhouse effect where solar energy is reflected by the amount of CO2, CFCs, methane, ozone, and N2O in the air layer, and damage to the ozone layer. Air pollution can have an impact on us due to the reason that these polluting substances enter our bodies when we breathe. The same applies to plants and animals.
