The formation of ozone hole in the Antarctic region has been a cause of concern. What could be the reason for the formation of this hole ?

• Increased temperature at polar region due to global warming.
• Absence of polar front and stratospheric clouds; and inflow of methane and chlorofluorocarbons.
• Presence of prominent tropospheric turbulence; and inflow of chlorofluorocarbons.
• Presence of prominent polar front and stratospheric clouds; and inflow of chlorofluorocarbons

The conditions for declaring a region as a 'biodiversity hotspot' are

• It must have rich biodiversity of plant and animal species and high degree of threat to that area
• It must contain certain number of endemic species of animals and high degree of threat to that area
• It must contain certain number of endemic species of plants and high degree of threat to that area
• It must contain certain number of exotic plant and animal species and high degree of threat to that area

If a wetland of international importance is brought under the ‘Montreux Record’, what does it imply?

• Changes in ecological character have occurred, are occurring or are likely to occur in the wetland as a result of human interference
• The survival of the wetland depends on the cultural practices and traditions of certain communities living in its vicinity and therefore the cultural diversity therein practices and traditions of certain communities living in should not be destroyed
• The country in which the wetland is located should enact a law to prohibit any human activity within five km from the edge of the wetland
• It is given the status of ‘World Heritage Site’
