Australian Bioethics Professor Peter Singer wants all of us to turn vegetarian and think hard about pointless consumerism.
He argues that those who eat meat are, indirectly, making other people go hungry.
He also says that if all those who can afford them stopped buying luxuries and gave the money to efficient charities instead, it would end global poverty very quickly.
Laudable aims, but are they realistic?
Former Iraqi Finance and Defence Minister Ali Allawi seeks to revitalize modern Islam and broaden its scope, so that, once again, it encompasses areas such as architecture, science, economics and medicine.

She also argues that attempts at quick technological fixes to reduce cruelty are likely to backfire, so what can we do instead?
