Consists of material objects, systems or ecosystems created or cultivated by humans.
Examples of man-made ecosystems are orchards, home aquariums, zoos, botanical gardens and parks. These ecosystems are sustained by human interventions. Aquarium and zoo ecosystems, for example, cannot survive without the care of humans. Man-made ecosystems are created for specific purposes.
A manufacturing process (often called a progressive assembly) in which parts (usually interchangeable parts) are added as the semi-finished assembly moves from workstation to workstation where the parts are added in sequence until the final assembly is produced. By mechanically moving the parts to the assembly work and moving the semi-finished assembly from work station to work station, a finished product can be assembled faster and with less labor than by having workers carry parts to a stationary piece for assembly.
A botanical garden or botanic garden is a garden dedicated to the collection, cultivation, preservation and display of a wide range of plants labelled with their botanical names. It may contain specialist plant collections such as cacti and other succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, shade-houses, again with special collections such as tropical plants, alpine plants, or other exotic plants.
Water Treatment Plants
Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities.
