I'm your Mother Earth and I would like to say some words to you, people.

First, I want to thank all people. You should try to take care of my health. But I must say that I'm still very angry. Many of you don't respect me and throw litters in the streets and parks in different ways: wastes and litters are everywhere. They kill so many animals and cut down so many trees.

Wild life is now in danger. If you don't stop all  this, life will be in danger. So please don't forget that I am your only home and protect me!

The modern English word and name for our planet ‘Earth’, is said to go back at least 1,000 years. Just as the English language evolved from ‘Anglo-Saxon’ (English-German) with the migration of certain Germanic tribes from the continent to Britain in the fifth century A.D, the word ‘Earth’ came from the Anglo-Saxon word ‘erda’ and it’s germanic equivalent ‘erde’ which means ground or soil. In Old English, the word became ‘eor(th)e’ or ‘ertha ‘. There is speculation that the origins of the word may be from an Indo-European language base ‘er’ which produced more modern adaptations of the word used in languages today. What is certain though is of all the Planet’s names, Earth is the only one in our solar system that does not come from Greco-Roman mythology. All of the other planets were named after Greek and Roman gods and goddesses.
