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.

What is growing that will cause greenhouse gasses to increase?

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.

All creatures need to eat something in order to survive. Fortunately, different species of animals have different things that they eat as food. No matter what a creature eats, the food must have enough calories in it to maintain life. Calories, or the energy stored in the food, provide the fuel animals, including humans, need in order to live and move about in the world. Any creature that does not consume enough food, or in other words enough calories, will starve and die.

The term calorie has a scientific meaning. Calorie is a measure of an amount of energy just like pound is a measure of weight. A calorie is officially defined as the amount of energy it takes to raise the temperature of 1 gram of water by 1 degree Celsius, which is 1. 8 degrees Fahrenheit. The term "calorie" and "Calorie" with a capital C have two different meanings to scientists. The term Calorie (with a capital C) means one kilocalorie, the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. A kilogram is the same as 1,000 grams and a kilocalorie is 1,000 calories. Food calories are always measured as Calories but average people don't care much about the difference and just use the word calories.Food is composed of proteins, fats and carbohydrates. Nutritionists know that a gram of protein contains 4 Calories, a gram of fat has 9 Calories, and a gram of carbohydrate has 4 Calories.

All food contains calories. When we eat something, it provides energy for our bodies to use when we are active. We even need energy or calories while we are sleeping because, for example, our bodies are still breathing, our heart is pumping, and we continue to digest the food in our stomachs. If a person eats more food and more calories than is used up by activity, the body stores the excess calories in case it might need it later when food might not be available. So a person gains weight due to the extra food and calories. Similarity, if a person consumes fewer calories than are used every day over several weeks and is more active, that person will lose weight.

Calorie is a measure of _______.

Reflexology is a natural treatment dating to ancient times. It is based on the idea that there are zones, or areas, in the feet and hands that are related to other parts and systems of the body. For example, the tips of the toes or fingers are related to head and neck, and the ball of the foot is related to the heart and chest. A reflexologist applies pressure to specific areas in a patient’s feet and hands to relieve symptoms or pain in other related areas.

This type of treatment does not cure or diagnose specific health problem, and it does not involve any medication. Yet many find that it successfully relieves symptoms of stress and disease. Reflexology is effective for pain, headaches, and sleeping difficulties, among other ailments. Applying pressure to the feet and hands relieves tension, improves blood circulation, and relaxes muscles. It promotes the natural, healthy functions and well-being of the entire body. Reflexology is often used along with other types of treatments, including conventional medicine.

This gentle therapy is safe and simple. A reflexologist’s only tools are his or her hands. Pressure is strong, but not uncomfortable. It’s not uncommon for patients to fall asleep during treatments.

A typical treatment session lasts one hour. Treatment is usually focused on the feet for most of the session. A patient is asked to remove his or her shoes and socks, to sit in a comfortable reclining chair, and then to relax as the reflexologist warms the patient’s feet with his or her hands and applies pressure to the appropriate parts of the foot. The last ten minutes of the session are dedicated to the hands.

After relieving specific problems, many patients continue a regular programme of treatment to maintain good health. Some reflexologists suggest building at least a five – minute reflexology session into every day for long – term relief of stress and pain.

Reflexology is a natural treatment which is based on the idea that.......................
