Explanation:

Water scarcity

Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.

It already affects every continent and around 2.8 billion people around the world at least one month out of every year.

More than 1.2 billion people lack access to clean drinking water.

Water scarcity involves water stress, water shortage or deficits, and water crisis.

While the concept of water stress is relatively new, it is the difficulty of obtaining sources of fresh water for use during a period of time and may result in further depletion and deterioration of available water resources.Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water.

A water crisis is a situation where the available potable, unpolluted water within a region is less than that region's demand.

Water scarcity is being driven by two converging phenomena: growing freshwater use and depletion of usable freshwater resources.

Water scarcity can be a result of two mechanisms: physical (absolute) water scarcity and economic water scarcity, where physical water scarcity is a result of inadequate natural water resources to supply a region's demand, and economic water scarcity is a result of poor management of the sufficient available water resources.

According to the United Nations Development Programme, the latter is found more often to be the cause of countries or regions experiencing water scarcity, as most countries or regions have enough water to meet household, industrial, agricultural, and environmental needs, but lack the means to provide it in an accessible manner.

The reduction of water scarcity is a goal of many countries and governments.

The UN recognizes the importance of reducing the number of people without sustainable access to clean water and sanitation.

The Millennium Development Goals within the United Nations Millennium Declaration state that by 2015 they resolve to "halve the proportion of people who are unable to reach or to afford safe drinking water."

According to baugh, what invention served to expose the artificiality of carpentered and painted stage forms?

KATRIN_1 [288]

According to Christopher Baugh, the invention of electric lighting beginning in the 1880s allowed for the exposure of the inherent artificiality of both the carpentered and painted stage forms, making them look more two-dimensional especially with respect to their three-dimensional scenic partners.

Prior to the use of electric lighting, gas or oil was used as the fuel to produce soft and gentle lighting that allowed for the blending of the carpentered and painted stage forms with the three-dimensional elements in the stage.

Explanation:

Self-regulation includes the process to maintain the stability of the emotions and thoughts, controlling them in the long run, and managing to produce positive results during the actions.

Performance is the second phase of self-regulation and it involves the learning processes. One of the key questions to consider during this phase is are there distractions and how can we get rid of them.

Any distractions during the performance phase can lead to more satisfying effects and usage of more time than it is planned and necessary. Distractions will lower the concentration and with it the control of the performance. This will have negative effects. Therefore, any distractions must be terminated while this phase of self-regulation is taking place.
