Compounds

The plants manufacture complex chemical compounds.

Carbon monoxide is a poisonous substance formed by the incomplete combustion of carbon compounds.

All life is based on chemistry and all living things are composed of chemical compounds.

Lipids are organic compounds.

Amines are nitrogenous compounds.

Organic compounds are generally molecular compounds.

Thirty years ago, the international community signed the Montreal Protocol on Substances that Deplete the Ozone Layer and began regulating ozone-depleting compounds.

The ozone hole over Antarctica is expected to gradually become less severe as chlorofluorocarbons—chlorine-containing synthetic compounds once frequently used as refrigerants – continue to decline. Scientists expect the Antarctic ozone hole to recover back to 1980 levels around 2070.

Fish, birds, and mammals are especially sensitive to even small amounts of toxic compounds in oil, fuel, and other petroleum products.

Although Europa is thought to have the ingredients needed to support life—water, energy, organic compounds—it lies outside of our solar system's habitable zone.
