Lake Burgas
Lake Burgas ( bg, Бургаско езеро, ''Burgasko ezero'') or Lake Vaya (езеро Вая, ''ezero Vaya''), located near the Black Sea west of the city of Burgas, is the largest natural lake in Bulgaria, with an area of 27.60 km2, a length of 9.6 km and a width of 2.5 to 5 km. It is up to 34 m deep. The lake's waters contain relatively little salt (about 4-11‰). Lake Burgas is inhabited by a wide variety of species, including 23 fish, 60 invertebrates and 254 bird species (of which 61 are endangered in Bulgaria and 9 in the world). An important fish-producing reservoir in the past, Lake Burgas lost much of its economic importance after the construction of the petrochemical plant near the city, but has witnessed an increasing number of species and decreasing pollution in recent years.

Bulgarian Black Sea Coast
The Bulgarian Black Sea Coast (), also known as the Bulgarian Riviera, covers the entire eastern bound of Bulgaria stretching from the Romanian Black Sea resorts in the north to European Turkey in the south, along 378 km of coastline. White and golden sandy beaches occupy approximately 130 km of the 378 km long coast. The region is an important center of tourism during the summer season (May–October), drawing millions of foreign and local tourists alike and constituting one of the country's most popular tourist destinations. Prior to 1989 the Bulgarian Black Sea coast was internationally known as the ''Red Riviera''. Since the fall of the Iron Curtain, however, its nickname has been changed to the ''Bulgarian Riviera''. The Bulgarian Black Sea Coast has a humid subtropical climate (Köppen climate classification ''Cfa''), with considerable maritime and continental influences. The area's average air temperature in the summer is about 28 °C, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burgas Lakes
The Burgas Lakes ( bg, Бургаски езера, ''Burgaski ezera'') or Burgas Wetlands (Бургаски влажни зони, ''Burgaski vlazhni zoni'') are a group of coastal lakes of varying saltiness located around the Bulgarian city of Burgas in the proximity of the Black Sea. They constitute the largest group of lakes in the country and comprise some of Bulgaria's biggest and most important lakes. The lakes' total area (including swamps, marshes, ponds and other reservoirs) amounts to 95 km2, of which 33.30 km2 are either proclaimed or proposed protected areas that are inhabited by a large number of locally or globally endangered species of birds, fish and mammals. Apart from this, the Burgas Lakes are also of economic importance, used to obtain sea salt and curative mud, as well as to supply the local economy with fresh water, in the case of Lake Mandrensko. The lakes comprise (in north to south order): * Lake Pomorie, an ultrasaline lagoon * Lake Atanasovs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...

Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over . The countries with most sites are the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...
