Polar seas is also an important habitat. There is an expected rise in the exploration and development of the Polar Seas due to an increasing demand for fuel and commodities. The emergence of China and India's economy is considered one of the main drivers of this phenomenon due to an unprecedented appetite for raw materials and fuel. Presently, there are still no exact figures that define the oil and gas reserves in the Polar Seas. Initial explorations, however, have resulted in the identification of its potential. For example, Canada's explorations discovered gas and oil in several Arctic locations such as Beaufort, High
