Google celebrated the 50th anniversary of Earth Day with a Doodle on Wednesday. Earth Day is celebrated on April 22 across the world. The internet giant has dedicated the doodle to one of the smallest and critical organisms-the bees. In the video clip, it shows a bee roams on all the flowers and how it helps in blooming a variety of other crops and flowering plants through pollination. It says the bees help 2-3rd of crops possible and 85 % of flowering plants by means of pollination.
