The Taima mandala is based on the Contemplation Sutra, but other similar mandalas have been made subsequently. Unlike mandalas used in Vajrayana Buddhism, it is not used as an object of meditation or for esoteric ritual. Instead, it provides a visual representation of the Pure Land texts, and is used as a teaching aid.
Sand mandala (Tibetan: དཀྱིལ་འཁོར།, Wylie: dkyil 'khor, THL kyinkhor; Chinese: 沙壇城/壇城沙畫) is a Tibetan Buddhist tradition involving the creation and destruction of mandalas made from colored sand.
There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic) and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living ...
Marine debris and marine aerosols refer to particulates suspended in a liquid, usually water on the Earth's surface. Particulates in water are a kind of water pollution measured as total suspended solids, a water quality measurement listed as a conventional pollutant in the U.S. Clean Water Act, a water quality law.

Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric ...
For example, each year, more than 6 million people die prematurely from indoor and outdoor air pollution. Short-lived climate pollutants are largely to blame. Fast actions on short-lived climate pollutants, such as the widespread adoption of advanced cook stoves and clean fuels, have the potential to prevent over 2 million of premature deaths ...
Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, and the natural or built environment. Air pollution may come from anthropogenic or natural sources.
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill. Non-point sources are more diffuse.
