Well, everyone knows that women are the ones who bring love in everyone's heart. Mothers, wives, sisters are very affectionate and there is another reason is that the population would die out because there would be no reproduction. Love,Care, Happiness, Softness, Beauty, Charm all are attributes of women only. The world would be incomplete. In any species/ organism, female is very important as it brings the generation forward. The presence of women in this world is very important as the other resources like land, water, air, etc. Human beings are known as renewable resource due to the presence of women.
hope this helps.... all the best!
