One of the gravest problems facing humanity right now is food security. The UN says that between 720 and 811 million people faced hunger in 2020. The State of Food Security and Nutrition in the World (SOFI) report specifically details the challenge with access to fresh produce.
In order to solve this challenge, we have seen people turn to vertical farming, a practice of growing crops in vertically stacked layers. Vertical farming not only rises from the need for fresh produce and climate challenges hindering access to it, but also from the ingenuity of farmers and technologists aiming to bring technology to improve food security.
