Welcome to Earth Day.
In this unit, you will explore the history of Earth Day and the ways in which people
today are working to protect our planet.
Earth Day is held each year on April 22.
It organizes support for environmental protection and raises global environmental awareness.
Earth Day was founded by U.S. Senator Gaylord Nelson.
He first came up with the idea for an environmental holiday in 1969, after he saw the damage done
by an oil spill off the coast of Santa Barbara, California.
At the time, pollution from industry, such as harmful fog called smog in the air
and toxic waste in the water, was widespread.
On April 22, 1970, twenty million Americans participated in peaceful protests for the
first Earth Day.
People came together because they wanted to see change in how the environment was treated
in their local communities, throughout the country, and around the world.
Their commitment to the environment helped launch a global movement.
Earth Day is now the largest nonreligious holiday in the world, celebrated annually
by more than one billion people in almost two hundred countries.
Despite the success of Earth Day, we still face many environmental challenges.
Animals are endangered due to changes in their natural habitats, and plastic pollution litters
the world’s oceans.
However, the challenges have inspired technological innovations.
For example, green vehicles like electric cars greatly reduce the pollution caused by
Renewable energy devices, such as solar panels and wind turbines, use sunlight and wind to
generate power for homes and reduce harmful impacts on the environment.
In this lesson, you will explore the history of Earth Day and how it has inspired people
worldwide to help care for the natural environment.
