Phoenix zones: where strength is born and resilience lives

Few things get our compassion flowing like the sight of suffering.

But our response is often shaped by our ability to empathise with others.

Some people respond to the suffering of only humans or to one person's plight more than another's.

Others react more strongly to the suffering of an animal.

These divergent realities can be troubling - but they are also a reminder that trauma and suffering are endured by all beings, and we can learn lessons about their aftermath, even across species.

Hope Ferdowsian has spent years travelling the world to work with people and animals who have endured trauma - war, abuse, displacement.

Here, she combines compelling stories of survivors with the latest science on resilience to help us understand the link between violence against people and animals and the biological foundations of recovery, peace, and hope.
