On a trip to New York, I visited the 9/11 memorial at One World Trade Center. I thought a lot about the relationship between war, peace, and architecture. After all, 9/11 and mass shootings are the only first-hand experiences I have had with war. In Normandy, France, where I grew up, the scars left by the first two world wars are omnipresent and most notable in the urban landscape. 

1 in 9 Americans were affected by food insecurity in 2018. That's 37 million people, including 11 million children who (according to the USDA's definition of food insecurity) do not have consistent access to enough food for an active and healthy life. Globally, 1 in 4 people – 1.9 billion – are moderately or severely food insecure.

What will we leave behind? How can we fix the future? Will we leave the world a better place than we found it? These questions have been haunting me for years.
