It is impossible to know the exact birthday of the Earth. Scientists estimate that our planet is about 4.55 billion years old, but this leaves a possible margin of error of millions of years – so we cannot know the exact year, let alone the exact day the Earth was formed. Earth Day is a US holiday established in the year 1970, to draw public attention to environmental issues. The first Earth Day in 1970 inspired massive citizen demonstrations across the country in favor of strong environmental reforms, and is credited with helping trigger the passage of some of our most important environmental laws. These days Earth Day doesn’t get quite so much attention – but it’s still an important reminder that our planet needs help.
