Earth Day 2026 is observed globally on 22 April with the theme 'Our Power, Our Planet' — commemorating the movement's 1970 origins when 20 million people participated in the first Earth Day in the United States, inspired by Rachel Carson's 'Silent Spring' and organised by US Senator Gaylord Nelson.

Earth Day 2026 is being observed globally on 22 April with the theme 'Our Power, Our Planet'. The day mobilises attention toward climate change, pollution, and biodiversity loss and emphasises that both individual and community actions can shape environmental outcomes. The observance traces its origins to the US environmental movement of the 1960s — particularly Rachel Carson's 1962 book 'Silent Spring', which documented the harmful effects of pesticide pollution, and US Senator Gaylord Nelson's nationwide campaign that culminated in the first Earth Day on 22 April 1970, with roughly 20 million people participating across the United States. The 2026 theme calls on individuals and communities to shift toward renewable energy sources, adopt sustainable lifestyles, and participate in local environmental initiatives. India's parallel policy architecture includes the National Action Plan on Climate Change (NAPCC), the Green India Mission, the International Solar Alliance, and the Swachh Bharat Mission.

• Trap · Earth Day vs World Environment Day

  Correct: Earth Day = 22 APRIL (first observed 1970, civic-movement origin). World Environment Day = 5 JUNE (UN-designated, 1972 Stockholm Conference origin). Two different observances with different origins.

• Trap · First Earth Day year

  Correct: 1970 — NOT 1962 (that is when Silent Spring was published) or 1990 (when Earth Day went global).

• Trap · First Earth Day scope

  Correct: The first Earth Day in 1970 was a US domestic observance with approximately 20 million participants. It did not become a global observance until 1990.

• Trap · Silent Spring topic

  Correct: Silent Spring (Rachel Carson, 1962) specifically documented the harmful effects of PESTICIDE POLLUTION — particularly DDT — not general pollution or climate change.

• Trap · ISA co-founder country

  Correct: International Solar Alliance co-founded by India and FRANCE (2015, COP21 Paris) — NOT the UK, Germany, or US. ISA is headquartered at Gurugram, India.

• Trap · NAPCC mission count

  Correct: NAPCC (2008) has EIGHT national missions. Key ones include Solar Mission, Enhanced Energy Efficiency, Water Mission, Sustainable Habitat, Green India Mission, Sustainable Agriculture, Strategic Knowledge for Climate Change, Sustaining Himalayan Ecosystem.
