Major endangered species in the Southern Aravalli region include the Indian leopard, Indian wolf, and striped hyena. Key reasons for wildlife loss in Rajasthan are habitat destruction, poaching, human-wildlife conflict, and climate change, which significantly impact biodiversity and ecosystems in the state.

Ozone layer depletion is primarily caused by chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances used in refrigeration, aerosols, and foam production. These chemicals release chlorine and bromine upon exposure to UV radiation, which breaks down ozone molecules.

The effects of ozone depletion include increased ultraviolet (UV) radiation reaching the Earth’s surface, leading to higher skin cancer rates, cataracts, and weakened immune systems in humans. It also adversely affects ecosystems, reducing crop yields, and harming marine life, particularly phytoplankton. Additionally, disruptions in weather patterns and climate change may occur, impacting biodiversity and global food security.

Rajasthan’s physiography and climate significantly influence its population distribution. The Thar Desert, with its arid conditions, supports sparse populations, while fertile plains like those around the Banas and Chambal rivers attract higher densities. The Aravalli Range creates varied microclimates, promoting agriculture in certain areas. Regions with irrigation facilities, such as Kota and Udaipur, see increased habitation. Conversely, extreme temperatures and limited water resources in desert areas hinder settlement. Additionally, urban centers like Jaipur and Jodhpur experience population growth due to economic opportunities, while remote areas face outmigration, reflecting the interplay of geography and climate on demographic patterns.
