[30MIN] On the Human Requirement of Love

Humans have engaged in romantic affairs since the dawn of their existence. But do humans really need love? Yes, because of three reasons; the biological need for love, the chemical effects of love, and the anthropological origins of relationships. Keep in mind that the term, ‘love’, is being used to describe all relationships, romantic or otherwise.
First of all, the obvious reason; reproduction. Humans must reproduce in order to keep their species alive for the generations to come, and thus must find a mate to begin copulating. What about adoption? Does that not invalidate the need to mate? No, for the adopter has to still raise the child, and that is statistically easier with two people. In addition, in order for a child to be adopted, the child must have first been born, as a result of others reproducing.
Secondly, humans derive pleasure from creating relationships. Relationships are often difficult to create, whether it be between colleagues, acquaintances, romantic partners, friends, or even family members. These take a lot of time to establish, so the human brain rewards people for achieving a relationship. Through bonding, the brain releases certain chemicals like dopamine, serotonin, and oxytocin; the chemicals responsible for the sensation of happiness. Without these chemicals, the individual in question will start to go into a depressive state, possibly driving oneself to insanity.
But why? Why will humans break down without social connections? Well, back when humans were hunter-gatherers, the power of groups was rather prominent. Groups would rely on each other for food, warmth, and most importantly, safety. If someone in the group refused to cooperate, they would be left behind to die. Despite not having the same risk of death now as they did back then, the anthropological need for bonding still remains. The human brain is conditioned to crave connection because of the influence of connections from long ago.
In conclusion, humans need love and relationships because biology mandates reproduction, chemistry rewards connections, and anthropology sets the desire for love, quite literally, in stone. Connections are important for both physical and mental health, so all humans should be encouraged to seek these relationships. Even if they do not come naturally now, love shall eventually find its way.
