An ancient farming system in which small patches of tropical forests are cleared and perennial polyculture agriculture practiced and is then followed by many years of fallow to restore the soil; also called swidden agriculture.

A naturally occurring, inorganic, crystalline solid with definite chemical composition and characteristic physical properties.

Repairing or rehabilitating a damaged ecosystem or compensating for damage by providing a substitute or replacement area.

Part of a hen’s natural reproductive cycle. After laying eggs for about a year, a
hen loses her feathers and rests for a few weeks as new feathers grow in. This
is called molting, or a molt, and it usually happens at the beginning of
winter. On factory farms, hens are subjected to forced molting, where farm operators
cause this process to happen rapidly by depriving hens of food and water for
several days and altering the schedule of light and darkness in the confinement
building. This way, all the hens molt simultaneously and over a very short time
period.

Environmental sabotage such as driving large spikes in trees to protect them from loggers, vandalizing construction equipment, pulling up survey stakes for unwanted developments, and destroying billboards.

Monoculture is the destruction of a diverse ecosystem and replacement with a single species
or crop. This is common practice in modern agriculture, where large acreages of
crops are grown for sale to other regions or countries. Monocultures deplete
the soil, and fruits and vegetables become more susceptible to pests and
disease than those grown in a diverse crop environment, thus requiring larger
amounts of chemical sprays.
