So one more captured here ( passing th8 ofcourse ;) )

We need energy to sustain life. Energy comes to us in the form of food intake we take majorly ( leaving apart solar energy ). Food we intake is a living thing ( be it veggies or non-veg ). Then why in order to live and get energy do we have to consume living things. Can't the energy we get from other sources be enough to get our lives through ??
