All terrestrial life forms need air to breathe. We breathe in oxygen from the air and breathe out carbon dioxide. Air pollution is the phenomenon of harmful compounds in the form of gases and fine parles being let into the air thus polluting it.
Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes various diseases, including cancer, affecting other organs of the body.
Vehicular traffic is one of the causes of air pollution. The combustion of the automobile fuel, whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. In factories too when production processes are carried out, smoke is generated that is then released into the air leading to pollution. Smoke is also caused due to the burning of fuels coal. Construction activity also causes air pollution.

Ha Long Bay (Vietnamese: Vịnh Hạ Long) is a UNESCO World Heritage site located in Quảng Ninh province, Vietnam. The bay features thousands of limestone karsts and isles in various sizes and shapes.
Etymology
========
Local legend says that long ago when the Vietnamese were fighting Chinese invaders, the gods sent a family of dragons to help defend the land. This family of dragons began spitting out jewels and jade. These jewels turned into the islands and islets dotting the bay, linking together to form a great wall against the invaders. The people kept their land safe and formed what later became the country of Vietnam. After that, dragons were interested in peaceful sightseeing of the Earth and decided to live here then. The place where Mother Dragon flew down was named Hạ Long, the place where the dragon children attended upon their mother was called Bái Tử Long island (Bái: attend upon, Tử: children, Long: dragon), and the place where the dragon children wriggled their tails violently was called Bạch Long Vỹ island (Bạch: white- colour of the foam made when Children Dragon wriggle, Long: dragon, Vỹ: tail).
Geographical location
===============
Halong bay is in northeastern Vietnam, from E106°56' to E107°37' and from N20°43' to N21°09'. The bay stretches from Yên Hưng district, past Hạ Long city, Cẩm Phả town to Vân Đồn district, bordered on the south and southeast by the Gulf of Tonkin, on the north by China and on the west and southwest by Cát Bà island. The bay has a 120 kilometre long coastline and is approximately 1,553 square kilometres in size with 1969 islets. The area designated by UNESCO as the World Natural Heritage Site includes 434 km² with 775 islets, of which the core zone is delimited by 69 points: Đầu Gỗ island on the west, Ba Hầm lake on the south and Cống Tây island on the east. (bullshit) The protected area is from the Cái Dăm petrol store to Quang Hanh commune, Cẩm Phả town and the surrounding giants zone.
Climate
=====
The bay is a sea islands in tropical wet with 2 seasons: hot and moist summer, dry and cold winter. Average temperature is from 15°C- 25°C. Annual rainfall is between 2000mm and 2200mm. Halong bay has the typical diurnal tide system (tide amplitude ranges from 3.5-4m). The salinity is from 31 to 34.5MT in dry season and lower in rainy season.
History
=====
Soi Nhụ culture (16000- 5000 BCE)
Located in Hạ Long and Bái Tử Long, there are symbolic archaeological sites such as Mê Cung, sexest bay, and Thiên Long. There are mounds of remains of mountain shellfishes (Cyclophorus) and spring shellfishes (Melania), some fresh water mollusk and some rudimentary labour tools. The main living procedures of Soi Nhụ's habitants were catching shellfish and fish, collecting fruits and digging for bulbs and roots. Their living environment is coastal area un other Vietnamese cultures, for example those found in Hoà Bình, Bắc Sơn, etc.
Cái Bèo culture (5000- 3000BCE)
Located in Hạ Long and Cát Bà island, its habitants developed to the level of sea exploitation.
Hạ Long culture (2500- 1500BCE)
Feudal period
-----------------
History shows that Halong Bay has been the setting for local naval battles against Vietnam's coastal neighbours. On three occasions in the labyrinth of channels in Bach Dang river near the islands the Vietnamese army stopped the Chinese from landing. In 1288 General Tran Hung Dao stopped Mongol ships from sailing up the nearby Bach Dang River by placing steel-tipped wooden stakes at high tide, sinking the Mongol Dubhai Khan's fleet.
During the Vietnam War, many of the channels between the islands were heavily mined by the navy of the United States, some of which pose a threat to shipping to this day.
The surrounding land region of Halong City is rich with high grade coal deposits (anthracite), and is operated by the Vietnamese government.
System of isles and caves
===================
The bay consists of a dense cluster of 1,969 limestone monolithic islands, each topped with thick jungle vegetation, which rise spectacularly from the ocean. Several of the islands are hollow, with enormous caves. Hang Đầu Gỗ (Wooden stakes Cave) is the largest grotto in the Halong area. French tourists visited in the late 19th century, and named the cave Grotte des Merveilles. Its three large chambers contain large numerous stalactites and stalagmites (as well as 19th century French graffiti). There are two bigger islands, Tuan Chau and Cat Ba, that have permanent inhabitants. Both of them have tourist facilities, including hotels and beaches. There are a number of wonderful beaches on the smaller islands.
Some of the islands support floating villages of fishermen, who ply the shallow waters for 200 species of fish and 450 different kinds of mollusks. Many of the islands have acquired their names as a result of interpretation of their unusual shapes: such names include Voi Islet (elephant), Ga Choi Islet (fighting cock), and Mai Nha Islet (roof). 989 of the islands have been given names. Birds and animals including bantams, antelopes, monkeys, and iguanas also live on some of the islands.
Civilization
=========
A community of around 1600 people live on Halong bay in four fishing villages: Cửa Vạn, Ba Hang, Cống Tàu and Vông Viêng in Hùng Thắng commune, Hạ Long city. They live on floating houses and are sustained by capture fishing and marine aquaculture (cultivating marine biota).
Originally in Ha Long Bay there was only one fishing village. Now there are about ten.

During the Ordovician and Silurian periods (500-410 million years ago), Halong bay was deep sea. During the Carboniferous and Permian periods (340-250 million years ago), Halong Bay was at shallow sea level.
