Civil rights and liberties: definition-amendments (1,5,6,13,14)-conflicts: freedom of expression and order. It is well known by now that the Bill of Rights was not a part of the United States Constitution and that it was added after the Constitution was ratified, at the request of some of the framers concerns for rights and freedoms found in the 1st, 5th and 14th amendments. The freedom of expression gives them the right to declare without fear any threat they feel in relation with any grievance they may encounter on a daily basis like, for example, school children being ill because of asbestos soundproofing materials in the school; or, people in their own home, suffering from sudden ailments such as nausea, migraine headaches, skin rash, eye and nose irritation all due to the terrible, silent killing pollutants in the air; asbestos in the workplace also poses a great danger to worker’s health.

Air pollution: definition and effects: Pollution is, since the beginning of time, the release in the environment, by human activities, of harmful substances (disturbing the relationship of all living things to their physical environment, and to each other, locally or over a large region) to any kind of life, including humans, plants, animals, insects, and small organisms that exist in the soil and water (Law 21).

Air is one of the four classical elements – air, water, earth, and fire
Air is the Earth's atmosphere. Air around us is a mixture of many gases and dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has no color or smell. It has mass and weight, because it is matter. The weight of air creates atmospheric pressure. There is no air in outer space.
Air is a mixture of about 78% nitrogen, 21% oxygen, 0.9% argon, 0.04% carbon dioxide, and very small amounts of other gases. There is an average of about 1% water vapour.
Animals live by aerobic respiration and need to breathe the oxygen in the air. In breathing, the lungs put oxygen into the blood, and send back carbon dioxide to the air. Plants need the carbon dioxide in the air to live. They give off the oxygen that we breathe. Without it we die of asphyxia.
Wind is moving air. This causes weather.
Air can be polluted by some gases (such as carbon monoxide), smoke, and ash. This air pollution causes various problems including acid rain and global warming.
Aircraft use propellers to move air over a wing, which allows them to fly. Pneumatics use air pressure to move things.
