Study Notes
Water Consumption and Availability
- Agriculture consumes approximately 70% of water in industrialized countries.
- The industrial sector is the largest consumer of water globally.
- About 70% of the world's freshwater is locked up in ice caps and glaciers.
- Countries like India and China are highlighted as facing severe water problems upon reaching the industrialization levels of wealthy nations.
- The domestic sector consumes more water than agriculture in industrialized countries.
- Oceans contain around 97% of the world’s water, which is unsuitable for drinking.
Environmental Impact of Agriculture and Deforestation
- The estimated annual cost of soil, water, and wind erosion due to deforestation in India is around $10 billion.
- Unsustainable agricultural practices lead to the loss of vital topsoil in forest ecosystems.
- Clear cutting and converting forest land for agriculture, plantations, and housing significantly disrupt quality and quantity of water resources in hilly areas.
- Human activities such as agriculture, urbanization, and logging destroy crucial habitats for endangered species.
- Pesticide spraying in forest plantations can have detrimental effects on surrounding wildlife and ecosystems.
Forest Types and Characteristics
- Evergreen coniferous forests typically contain species like pine, spruce, and fir.
- Boreal forests are characterized by long, cold, dry winters with limited sunlight.
- Coniferous forests feature trees with needle-like leaves and cone-borne seeds.
- Tropical Moist Deciduous forests are mainly located in the southern regions of India, including states like Kerala and Tamil Nadu.
- A unique forest type in India extends as a North-South strip from the Himalayas to Kanyakumari containing diverse species.
Vulture Population Decline and Its Effects
- The primary reason for kidney failure in vultures was the consumption of livestock treated with the anti-inflammatory drug diclofenac.
- With the decline of vulture populations, the wild dog population increased, leading to more scavengers.
- The rapid spread of the rabies virus among villagers in India was related to the increased wild dog population.
- Vultures played a critical role in controlling pathogens like rabies, reducing disease prevalence in ecosystems.
- Decreased vulture populations have led to increased human-leopard encounters due to altered food chain dynamics.
Environmental Awareness and Challenges
- Parsis faced a dilemma in disposing of their dead without vultures, disrupting traditional practices.
- Environment Studies have gained importance as awareness of ecological crises rises.
- A general lack of public awareness about environmental issues stems from ineffective education and outreach.
- Wealthy individuals often fear environmental initiatives due to potential economic impacts on their lifestyles.
- False anti-environment propaganda arises from vested interests opposing regulations.
- Lack of reliable environmental information hampers public understanding and engagement.
- Political parties frequently prioritize short-term gains such as economic growth over long-term environmental conservation efforts.
