Join us for two interactive sessions exploring the meal's role in a circular economy for food. We'll discuss how tomorrow's food can be grown regeneratively, tackling climate change and boosting biodiversity through natural systems. Experts will share visions on technology and urban-rural relationships.

The second session focuses on returning nutrients to the land. Imagine a future where discarded organic materials are valorized, becoming valuable inputs instead of waste. By preventing edible food waste and redesigning products, by-products will enrich the wider economy, safely returning vital nutrients to the soil.

Giant water bugs are exceptional fathers. After mating, females of some species cement their eggs to the male's back, then depart, leaving him to parent alone.

For over two weeks, the male diligently cleans, aerates, and fiercely defends the eggs from predators until they hatch.

Research indicates that female giant water bugs prefer males already carrying eggs, suggesting that strong paternal care is a highly valued trait in sexual selection.
