The area lies about 900 kilometres north of Vancouver. The nearest town is Kispiox, with a population of 300 people. The contested land is part of the Skeena Watershed, with the headwaters of several major salmon streams, as well as having untouched habitats for wildlife. The water is derived from snowmelt off local mountain ranges, as well as glacial runoff and local wetlands. The Klappan Valley is considered sacred by First Nations people. It is still an important part of the local economy through salmon-fishing, as well as providing a place to educate youth about traditional ways and knowledge.

The latest example is a large Turkish ship, carrying 1,000 tonnes of crude oil, off the coast of Croatia. Und Adriyatik is carrying trucks and unspecified “dangerous material” - said to be oil products. It caught fire, requiring full evacuation of the crew and passengers. Now, currents are driving the unmanned ship near the coast. The coast of Croatia is a popular tourist destination, and any oiling would have devastating consequences. Ironically, Croatia just declared a protected coastal zone to prevent just such an accident, as well as decreasing fishing pressure. A stinky issue

The issue is high concentrations of the gas from the facility, which mines the oil sands as well as processing synthetic crude. The production capacity is about 260,000 barrels per day. Hydrogen sulphide, more familiar as the nasty smell of rotten eggs, is not just unpleasant, it can be deadly. It occurs naturally in crude petroleum and natural gas, as well as in volcanic areas, from decomposition of organic matter, and through industrial processes. Hydrogen sulphide gas spreads, remaining in the atmosphere for about 18 hours, and transforming into sulphur dioxide and sulphuric acid. |

Worldwide markets and global businesses have made the world seem smaller. Apples from South America, toys from China, clothes made in Vietnam - these are all common sights in the local store. Part of the eventual price depends on transportation, often involving large cargo ships for transoceanic shipping. And this has its own hidden costs. Time and time again, accidents happen and oil ends up in the ocean.
