Deutsch: Monokulturlandwirtschaft / Español: Agricultura de monocultivo / Português: Agricultura de monocultura / Français: Agriculture en monoculture / Italiano: Agricoltura monoculturale

Monoculture farming in the environmental context refers to the agricultural practice of growing a single species of plant over a large area and for a prolonged period. This method is widely used in modern agriculture to increase efficiency in planting, managing, and harvesting crops, often leading to higher yields of commodities such as wheat, corn, soybeans, and rice. While monoculture farming can offer economic benefits and meet the demand for certain crops, it also presents significant environmental challenges.

"Monoxide" refers to a compound composed of one atom of oxygen and one atom of another element, typically a metal or non-metal. Monoxides can have various environmental implications, particularly in relation to air pollution and human health.

Deutsch: Motor / Español: Motor / Português: Motor / Français: Moteur / Italiano: Motore

A motor in the context of the environment refers to any machine or device that converts energy into mechanical motion, powering vehicles, machinery, or equipment. Motors are integral to transportation, industrial processes, and energy systems, and their environmental impact varies depending on the type, energy source, and efficiency of the motor in use. Conventional motors are often powered by fossil fuels, which contribute significantly to greenhouse gas emissions, air pollution, and environmental degradation.

Motor gasoline is a complex mixture of relatively volatile hydrocarbons, with or without small quantities of additives, obtained by blending appropriate refinery streams to form a fuel suitable for use in spark-ignition engines.
