Love is what keeps the world go around. Imagine what the world be like without it. Everyone would go about their business with hate, anger and depression. Without love, the world would be nothing. No one would get along and there would be fights in every home, every day.
The world would not have any sort of future, whatsoever. There would be no children to carry on our legacy and change the world in a more positive way, in their own little way. Death would be everywhere, even more than there is now in a more grander scale.
Children are so full of love waiting to share with the world. Look at a child's bright, smiling face and you'll see all the love in the world. That's why we all say that children are our future. We just have to show them how to express that love in a really positive way. We, as adults, are their teachers after all. If we show them hate, then that's all they know what to show and they'll think it's “love.” But if we show them love then that's what they'll know is true love.
