How method to write a preface about environmental science

Air pollution is linked to asthma, allergies and other respiratory illnesses. You can more about how the environment affects human health here.
Land Pollution

Land pollution is the degradation of the Earth's surface caused by a misuse of resources and improper disposal of waste. Some examples of land pollution include:
Litter found on the side of the road
Illegal dumping in natural habitats
Oil spills that happen inland
The use of pesticides and other farming chemicals
Damage and debris caused from unsustainable mining and logging practices
Radiation spills or nuclear accidents
Land pollution is responsible for damage done to natural habitat of animals, deforestation and damage done to natural resources, and the general ugly-ing up of our communities. (So stop being a litterbug, eh?)
Light Pollution
more stars from less light pollution
Light pollution is the brightening of the night sky inhibiting the visibility of stars and planets by the use of improper lighting of communities. Some examples of what causes light pollution:
Street lamps that shine light in all directions, instead of with a hood to point light downward toward the street.
Extra, unnecessary lights around the home
Cities that run lights all night long
Light pollution uses more energy (by shining more light up instead of down, meaning you need brighter bulbs for the same amount of light), may affect human health and our sleep cycles, and most importantly, corrupts our kids telescopes and their curiosity. (I grew up in a city. My first no-light night in the country blew my mind. Let's not make that such a rare occasion!)
Noise Pollution

Noise pollution is any loud sounds that are either harmful or annoying to humans and animals. Some exmaples of noise pollution:
Airplanes, helicopters, and motor vehicles
Construction or demolition noise
Human activities such as sporting events or concerts
Noise pollution can be disruptive to humans' stress levels, may be harmful to unborn babies, and drives animals away by causing nervousness and decreasing their ability to hear prey or predators.
Thermal Pollution
warm lake water from thermal pollution
Thermal pollution is the increase of temperature caused by human activity. A few examples of this include:
Warmer lake water from nearby manufacturing (using cool water to cool the plant and then pump it back into the lake)
Included in thermal pollution should also be the increase in temperatures in areas with lots of concrete or vehicles, generally in cities
These kinds of environmental pollution can cause aquatic life to suffer or die due to the increased temperature, can cause discomfort to communities dealing with higher temperatures, and will affect plant-life in and around the area.
Visual Pollution

Visual pollution is what you would call anything unattractive or visualing damaging to the nearby landscape. This tends to be a highly subjective topic. Some examples of visual pollution:
Skyscrapers that blocks a natural view
Graffiti or carving on trees, rocks, or other natural landscapes
Billboards, litter, abandoned homes, and junkyards could also be considered among three kinds of environmental pollution
Mostly, visual kinds of environmental pollution are annoying and ugly, although some may say they are also depressing, and they of course affect the surrounding landscape with the changes they cause.
