The Stockholm Conference on Human Environment was held on June 5, 1972, in Sweden. Since then, this day has been celebrated as World Environment Day.

Ultraviolet radiation is the main cause of cataract. Exposure to UV radiation from the sun or other sources can damage the lens of the eye, leading to the development of cataracts. This is supported by research that shows a higher prevalence of cataracts in individuals who are frequently exposed to UV radiation, such as outdoor workers or individuals living in sunny regions. Protecting the eyes from UV radiation by wearing sunglasses and hats can help reduce the risk of developing cataracts.

Mercury is the correct answer because it is a metal that is commonly found in broken fluorescent bulbs, tube lights, and dead batteries. It can be transported with common municipal solid waste and can easily be swallowed, inhaled, or absorbed through the skin. Mercury is known to cause damage to the kidneys and nervous system, making it a harmful substance to human health.

The Geysers, located north of San Francisco, USA, is known for being the world's largest source of geothermal power. Geothermal power harnesses the natural heat from the Earth's core to generate electricity. The Geysers is a geothermal field where steam is produced from underground reservoirs of hot water. This steam is then used to power turbines and generate electricity, making it a significant source of renewable energy in the region.

The major concerns regarding the Narmada Valley Project include the submergence of over 4000 sq. km. of forest, cultivated land, and grazing land. Additionally, between 1 and 1.5 million people will be displaced as a result of the project. Furthermore, at least 40% of the land that is planned to be irrigated is prone to water-logging and salination. These concerns highlight the potential environmental and social impacts of the project, including loss of land and livelihoods, as well as the degradation of agricultural land.

Marine life primarily relies on phytoplankton as their main source of food. Phytoplankton are microscopic plants that float in the ocean and undergo photosynthesis to produce energy. They are the foundation of the marine food chain, as they are consumed by zooplankton, which are then eaten by larger organisms. Phytoplankton provide essential nutrients and energy to sustain the entire marine ecosystem. Sea weed and grass may also provide food for some marine species, but they are not the primary source like phytoplankton.

The correct answer is 48A and 51G. These two articles in the Constitution of India outline the responsibilities of both the State and the citizens in environmental protection. Article 48A states that the State shall endeavor to protect and improve the environment and safeguard the forests and wildlife of the country. Article 51G states that it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife. These articles highlight the shared responsibility of both the State and the citizens in ensuring environmental protection.

The Wildlife Week is celebrated from 2-8 October. This is the correct answer because it is the only option that states the correct dates for the celebration.

Therefore, the answer 2-8 October is the most accurate and logical choice.

Maharashtra is the correct answer because it was the first state to implement the path-breaking proposal of including the environment as a separate subject in schools.
