Google celebrated Earth Day 2024 by replacing the letters with photos of some of the places around the world "where people, communities and governments help protect the planet's natural beauty, biodiversity and resources every day," the company explained. And so the letter G shows the Turks and Caicos Islands; first O the Arrecife Alacranes (the largest coral reef in the southern Gulf of Mexico); the other O is Vatnajökull, in Iceland, the largest glacier in Europe; the second G is Jaú National Park in the Brazilian Amazon; L shows the Great Green Wall in Nigeria, an ambitious project launched in 2007 to create a large belt of vegetation more than 7 thousand kilometers long from the west coast of Africa, in Senegal, to the east coast in Djibouti; E finally shows the Pilbara Islands Nature Reserve in Western Australia.
