Earth is the planet where life persists. The earth is said to be round in shape, but the exact shape of the earth is oblate spheroid. Earth comes between Venus and Mars in the solar system. There are several realms of the earth i.e. the lithosphere, hydrosphere and atmosphere. Structure wise, earth is made of the crust, the core and the mantle.
Earth is our planet, which we inhabit. Heaven follows the earth. According to C.S. Lewis, “if you aim at heaven and you will get the earth thrown in. Aim at earth and you will get neither.” You have to aim high to realise your aim. Remember, even the sky is not the limit. So, dare to dream big. People believe in service of the society and indulging in social service of the entire human race on earth. In this context, the words of Muhammad Ali strike our mind. Quote verbatim, “Service to others is the rent that you pay for your own small room here on earth.” So, help others and think for the benefit of the entire human race.
