Places where seawater and rainwater is pumped away are included. Fully natural places below sea level require a dry climate; otherwise, rain would exceed evaporation and fill the area. All figures are in meters below mean sea level (as locally defined), arranged by depth, lowest first:
The Prayagraj Mela Committee set up 150,000 toilets and urinals in the Maha Kumbh area, and a monitoring system was launched to track sanitation levels in toilets. About 10,000 sanitation workers were engaged for cleaning activity. [22] One cleaner was allocated for every ten toilets with a supervisor monitoring a batch of ten such personnel. [23]
If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 between 30 cm (1 ft) and 1.0 m (3 + 1 ⁄ 3 ft) from now and approximately 60 cm (2 ft) from the 19th century. With high emissions it would instead accelerate further, and could rise by 50cm (1.6 ft) or even by 1.9 m (6.2 ft ...
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
Mountains: Nationally designated protected areas cover 14.3% of the world's mountain areas, and these mountainous protected areas made up 32.5% of the world's total terrestrial protected area coverage in 2009. Mountain protected area coverage has increased globally by 21% since 1990 and out of the 198 countries with mountain areas, 43.9% still ...

An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation.
An analysis in 2004 of long term records from four New Zealand tide gauges indicated an average rate of increase in sea level of 1.6 mm a year for the 100 years to 2000, which was considered to be relatively consistent with other regional and global sea level rise calculations when corrected for glacial-isostatic effects.
