Death zone:

The term ‘death zone’ describes the area of Mount Everest above 7,900 metres (26,000 feet). Above this height the shortage of oxygen restricts the normal functions of the human body. Many climbers who stay for extended periods in this area begin to develop serious, if not fatal health problems as a result. In the death zone there is only 33 per cent of the oxygen available in the air at sea level! This shortage of oxygen is the reason why many mountaineers climbing in the death zone use breathing apparatus.

Deforestation:

Clearing away trees from an area

Democracy:

Government of a country by representatives elected by the population.

Diet:

The sort of foods usually eaten by a person or an animal.
