This 22nd April 2018 we observed the World Earth Day with the theme 'End Plastic Pollution'. The first World Earth Day was observed 48 years ago with the efforts of a US Senator. Who among the following US Senators are credited for initiation of World Earth Day?

Gaylord Nelson

Kamala Harris

Nikki Haley

Ernest Gruening

Explanation:

First option is correct.

The World Earth Day (WED) is celebrated every year on April 22 worldwide to demonstrate support for environmental protection. The day was proposed at the UNESCO conference in 1969 and the first Earth Day celebrations took place in 1970. The person credited with organising the event 48 years ago is US Senator Gaylord Nelson. The 2018 campaign theme ‘End Plastic Pollution’ will provide the information and inspiration needed to fundamentally change human attitude and behaviour about plastics.

Nikki Haley and Kamala Harris are US Senators of contemporary times and would have been infants 48 years ago. US Senator Ernest Gruening is credited with vocal support to Rachel Carson's 'The Silent Spring' and the senator spoke, "Every once in a while in the history of mankind, a book has appeared which has substantially altered the course of history."
