Explanation:
Matter is defined as anything that occupies space and has mass, and it is all around us. Solids and liquids are more obviously matter: We can see that they take up space, and their weight tells us that they have mass. Gases are also matter; if gases did not take up space, a balloon would stay collapsed rather than inflate when filled with gas.
Solids, liquids, and gases are the three states of matter commonly found on earth (Figure 1). A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of a container, except that it forms a flat or slightly curved upper surface when acted upon by gravity. (In zero gravity, liquids assume a spherical shape.) Both liquid and solid samples have volumes that are very nearly independent of pressure. A gas takes both the shape and volume of its container.
A beaker labeled solid contains a cube of red matter and says has fixed shape and volume. A beaker labeled liquid contains a brownish-red colored liquid. This beaker says takes shape of container, forms horizontal surfaces, has fixed volume. The beaker labeled gas is filled with a light brown gas. This beaker says expands to fill container.
Figure 1. The three most common states or phases of matter are solid, liquid, and gas.
A fourth state of matter, plasma, occurs naturally in the interiors of stars. A plasma is a gaseous state of matter that contains appreciable numbers of electrically charged particles (Figure 2). The presence of these charged particles imparts unique properties to plasmas that justify their classification as a state of matter distinct from gases. In addition to stars, plasmas are found in some other high-temperature environments (both natural and man-made), such as lightning strikes, certain television screens, and specialized analytical instruments used to detect trace amounts of metals.

Pros: The rate at which modern medicine is advancing is astonishing. You can sit on your couch and watch TV and see commercials for new medications at an alarming pace — and these new medications have reduced our death rates for stroke, heart disease, and cancer. In fact, due to modern medicine, the death rate from heart disease has decreased by 60% since 1970! The death rate for HIV/AIDS has dropped more than 75% since 1995, when its was at its peak.
Cons: However, critics of modern medicine are quick to point out that there is a pill for everything . Yes we are quick to create more drugs, and yes, we are living longer due to said drugs but are we living better?
Medicine has evolved, and we now have surgeons who are able to perform surgeries robotically. But critics point out that medicine has evolved to the point that we are treating disease instead of preventing it .
Chlorofluorocarbons and other halogenated ozone depleting substances are mainly responsible for man made chemical ozone depletion.
