Environmentalism Gaining Momentum – Denis Hayes and Earth Day

  • László Erdős


Earth Day was first proposed by peace activist John McConnell and Democrat Senator Gaylord Nelson. The principal organiser of the first Earth Day in 1970 was Denis Hayes. The first large-scale green event of the world was extremely successful with an estimated 20 million participants. Earth Day 1970 had a massive effect. It united various environmental branches and organisations under a common flag and changed people’s attitude toward the environment. Major environmental laws were passed that would have been unthinkable a few years earlier. Earth Day developed into a global event and became the largest secular holiday of the world.
