Last but not least

In the next post I will be concluding the blog, after having exhausted the literature and attempting to gain both sides of the story for each theory, so to speak. If you look in the right-hand sidebar I have added a list of the theories I have discussed (although many of these are interlinked, for example agricultural failure and deforestation or agricultural failure, disease and diets). Hopefully this will simplify things and remind you of what has been mentioned over the past couple of months, so you too can come up with your own conclusions!
