Climate scientists from the University of Sydney in Australia say tourism causes over 8 per cent of greenhouse gasses. They also say that this figure will continue to increase because the tourism industry is growing. Their study looked at the carbon footprint of many different areas of tourism. It studied the CO₂ emissions from transport, events, hotels, restaurants and shopping. It even researched the carbon emissions from producing souvenirs. The researchers spent 18 months conducting the research. They included the tourist activities of 189 countries. Researcher Dr Arunima Malik said her team analysed the impact on the environment of over one million businesses involved in tourism.

The researchers said domestic travel was a bigger cause of CO₂ emissions than international or business travel. Air travel was the largest part of tourism's footprint. The researchers said flying would continue to increase global emissions as more people in the world become richer. The countries causing the most harm were the biggest and richest nations. The USA, China, India and Germany had the largest tourism carbon footprints. Their carbon emissions will continue to increase as more of their citizens travel. The researchers encouraged holidaymakers and travelers to try and reduce their carbon footprint when on vacation so their travel causes less harm to the planet.

Polar bears on an island in Russia are scaring people in a small town. At least 52 polar bears have been seen wandering around the town of Belushya Guba. The town is on the island of Novaya Zemlya, which is in the Arctic Ocean. The situation has become serious because the bears have chased people and entered homes and offices. Local officials have declared a "polar bear emergency". Local official Alexander Minayev said: "The people are scared. They are frightened to leave homes and their daily routines are broken. Parents are afraid to let their children go to school or kindergarten." A local said: "I have been [here] since 1983, but there have never been so many polar bears in the vicinity."

Officials say the polar bears are roaming into towns looking for food. They say that climate change is one reason for this. More sea ice is melting, which means the bears are moving into new areas to find food. They are attracted by the smell of food in bins outside people's homes. Town officials have asked for permission to kill the animals to reduce the danger to humans. However, Russia's environmental agency has refused this request. Polar bears are classed as a vulnerable species. The World Wildlife Fund says they are in danger because of the "ongoing and potential loss of their sea ice habitat resulting from climate change". It is helping to keep the polar bears away from the people of Belushya Guba.

In which body of water is the island in this news story?

Where was the food that the polar bears could smell?
