British Medical Journal: Climate change “poses an immediate and grave threat, driving ill-health and increasing the risk of conflict, such that each feeds upon the other.” | ThinkProgress And like all good medicine, prevention is the key. The British Medical Journal has a must-read editorial reviewing and synthesizing recent reports on climate change, public health, and national security. The lead author of Climate change, ill health, and conflict, is Lionel Jarvis, surgeon rear admiral of the UKs Ministry of Defence. I repost it below in full with links to the references: Damage to the fabric of human society is bad for human health. It can occur for reasons other than war.

Starvation, diarrhoea, and infectious diseases will become more common, and neonatal and adult mortality will rise, as a result of conflict.2 In accordance with this, in 2004, seven of the 10 countries with the highest mortality rates in children under 5 were conflict or immediate post-conflict societies.3.
