Top 10 Environmental Speakers for Earth Day 2021

On April 22, 1970, millions of Americans participated in the first Earth Day – an environmental movement that has since mobilized activists in over 193 countries, led to the establishment of the Environmental Protection Agency (EPA), and pushed for landmark legislation acts such as the Clean Air Act, the Clean Water Act, and the Endangered Species Act. According to Earth Day’s official website, it is “the largest secular observance in the world” as over a billion people use this day of awareness to tackle climate issues on a global, national, and local scale.

The need for awareness and meaningful change has only become more urgent, as the consequences of our climate crisis are now more apparent than ever. In 2020, Earth Day celebrated its 50th anniversary amid a global pandemic after a year of record heat, wildfires, and floods. The reality we’re all facing now is a grim one. COVID-19 has already laid bare the deeply rooted social injustices and inequality facing vulnerable communities – the same communities that have been disproportionately affected by climate change. But, as we now look forward to Earth Day 2021, we also look forward to a year of healing. This is reflected in this year’s Earth Day theme: “Restore Our Earth.” It’s a theme rooted in the idea of revival and hope, but not without decisive action.

Climate change and pandemics might define our future if we don’t adapt our impact on the environment and restore the planet’s ecosystems. The following environmental speakers are not only spreading awareness about the natural and technological solutions to climate change already within our grasp, but are also inspiring others to work toward making a better home for us all.

1. Erin Brockovich

Consumer Advocate, Author, TV Host & Environmental Activist

Erin Brockovich is an American legal clerk, consumer advocate, and environmental activist, who, despite her lack of education in the law, was instrumental in building a case against the Pacific Gas and Electric Company of California in 1993. Her successful lawsuit was the subject of a 2000 film, Erin Brockovich, which starred Julia Roberts.

 After uncovering a 30-year long history of poisoning the groundwater in California, Brockovich dug in and didn’t give up until she had exposed the truth – and had gotten justice for its victims. She truly is proof that one person can make a difference, and she believes that everyone – in their own way – can do the same. Seen by millions as a symbol of American justice and the importance of fighting for the truth, Brockovich continues to speak out on behalf of those who can’t.
