The group, called the Haida Salmon Restoration Corporation, is supported by the village of Old Massett, British Columbia.

About 700 people live in the village, which is located on the Haida Gwaii islands.

They used to make their living by fishing for salmon, but now there are not enough salmon and 70 per cent of the villagers don’t have jobs.

Last July, the Haida Salmon Restoration Corporation paid $2.5 million to an American businessman named Russ George to dump a mixture of iron sulphate and iron oxide dust into the ocean about 370 kilometres west of the islands.

They hoped the iron would cause more plankton to grow in that part of the Pacific.

They believed that more plankton would help increase the number of salmon in the area.

Curiosity landed on Mars in August 2012 after travelling through space for more than eight months.

It was sent to Mars by scientists from NASA in the United States.

Curiosity is a motorized vehicle called a “rover” which is controlled by scientists back on Earth.

It is about the size of a car and has six wheels that allow it to travel across the planet’s surface and climb over sand and rocks.

It also has a robotic arm, cameras, and instruments such as a scoop, drill and microscope that allow it to examine things it finds on the surface.

Then it transmits the information back to Earth.

The main purpose of Curiosity’s mission is to find out if anything could live on Mars, either now or in the past.

On Nov. 2, NASA scientists held a press conference to discuss what Curiosity had found in its first two months on Mars.

The mummy is nicknamed “Ötzi the Iceman.” He was discovered in 1991 by two people hiking in the Alps in Italy.

By examining the body, scientists found that Ötzi (pronounced “`oetsi”) died from an arrow wound about 5,300 years ago. His body was preserved by ice and snow.

They discovered that he about 45 years old when he died, 1.6 metres tall and weighed 50 kilograms. He wore a goatskin coat, had shoes made from grass and deerskin, and he carried a bow, an arrow and some tools.

Recently scientists have learned even more about the Iceman, by studying his DNA. DNA is a collection of molecules that contains information about the characteristics of an individual plant or animal. This information is stored in the cells that make up each individual.
