I really wasn’t sure what to expect from the Festival of Dangerous Ideas.  This was not my usual scene.  FODI has been the home of some strange and disturbing thinking.

In fact the organisers had earlier had to cancel a talk by a Sydney-based Muslim speaker titled Honour Killings Are Morally Justified.

So as I walked into the Sydney Opera House on Saturday I decided to approach the festival with an open yet skeptical mind.

What I was really interested in was a talk by Kajsa Ekman on the topic of surrogacy. Ekman is a Swedish journalist and activist. She’s the author of the book Being and Being Bought: Prostitution, surrogacy and the split self.

Given the recent controversy surrounding surrogacy, including the heart-wrenching story of baby Gammy, I wanted to hear what Ekman had to say.

Here are three things I learned about surrogacy from Ekman’s talk at the Festival of Dangerous Ideas.

Surrogacy is baby trading

This position is difficult to refute. The surrogate mother doesn’t get paid for being pregnant. Rather, she is paid for handing over a baby. Money changes hands and the item being purchased is a new born baby. This is the ultimate in the commodification of humanity and is blatant buying and selling of children—a modern form of human trafficking.

Surrogacy exploits women in poverty

Supporters of surrogacy argue that women who are trapped in poverty can change their circumstance through selling the rights to their womb. Singles or couples are prepared to spend tens of thousands of dollars to get a child.

In defending the right to commercial surrogacy we are defending the interests of the world’s richest people to purchase a family.

Some people argue that because some women are poor, they should sell their womb in order to survive. Poverty becomes an excuse for exploitation. Is that the kind of world we want? This is commercialising life itself – everything is for sale, while those facilitating the transaction get rich. Surrogacy demeans the unique mother-child bond as women can now solely be used as breeding machines.

Surrogacy violates the rights of children

Surrogacy is too often a bad bargain for both the women and children involved in the process.

The UN Declaration on the Rights of the Child affirms that a child must not, "save in the most exceptional circumstances, be separated from his mother", and yet surrogacy does exactly that.  It is deliberate and premeditated.

Australian ethicist Professor Margaret Somerville condemns any deliberate destruction of the child's biological identity. She says:

"It is one matter for children not to know their genetic identity as a result of unintended circumstances. It is quite another matter to deliberately destroy children's links to their biological parents, and especially for society to be complicit in this destruction."

Helping an infertile couple to have a baby of their own is seen by many as a generous and compassionate gesture from a woman who can help. In this way, everyone can have their own children without having to be pregnant, and poor women can earn some extra money. It looks like a win-win situation. But at a closer look, the surrogacy industry is an exploitation of women's bodies and a sophisticated form of baby trade.
