; Where is the Black Sea located?; Why is it called the Black Sea?; What are the main tourist centres in the Black Sea region?; Is the water in the Black Sea fresh or salty?; What is the wildlife of the Black Sea like?; Are there any natural resources in the Black Sea area?; What ecological problems does the Black Sea have?; The deep layers of the Black Sea contain a lot of salt and almost no oxygen, so even bacteria find it difficult to survive in those waters. Shipwrecks at the bottom do not rot, but are preserved untouched. In contrast, the upper layer is warm and inhabited. More than 200 types of fish live there, and some of them exist only in this sea. There are shrimps and crabs, too. And, of course, the tourists are delighted to see the dolphins there!; At first glance, the Black Sea looks like an ordinary saltwater basin, with typical, but not flourishing, flora and fauna – but it’s much more complex than that! Long ago, the Black Sea was a freshwater lake. Later, the water from the Mediterranean Sea began to flow in, which made the Black Sea salty. Today, it has both freshwater and saltwater. The upper layers are fresher due to large rivers flowing into the sea, while the deeper parts are saltier.; In addition to its natural wonders, safe waters, and popularity with tourists, the Black Sea is important to people for economic and development reasons. Oil and natural gas reserves beneath the sea are large, and their importance for industries is indisputable. Different minerals, such as manganese, copper, and even gold, can also be found in the region. The coastal areas also have sand, gravel, and other useful materials.; The Black Sea is the largest inland sea in Europe. Six countries have access to its coast. It has always been important for trade, transport, and tourism. The Black Sea is one of the favourite holiday destinations for families with children, due to its safe waters – no sharks, and no poisonous jellyfish! The sea connects to the Mediterranean Sea through the Bosphorus Strait in the southwest, and to the Sea of Azov via the Kerch Strait in the northeast.; Sadly, the Black Sea’s beauty comes with a warning. Fishing has always been one of the leading industries there, but overfishing has reduced the fish population and upset the marine ecosystems. Pollution is also a big danger. Factories and cities often throw waste into the sea. Gas and oil exploration, and drilling for them under the sea, adds to oil and noise pollution, which is harmful to dolphins and other sea inhabitants.; Can water look black? Of course, it may, when it is dirty, muddy or heavily polluted, but that is not the case with the Black Sea. Long ago, Greek sailors called it black, as they thought it was dangerous because of storms and hostile tribes on its coast. Some historians believe the name comes from old traditions that denote directions with colours. In that system, black meant north , so the Black Sea was simply the sea in the north .
