Travel through the countryside during the day, and you might think the fields and forests are empty, but nature is alive with activity at dawn and dusk. Like humans, animals have a rush hour - where they take advantage of cooler temperatures, avoid humans, and hide from predators.
In the desert, animals forage at dawn before the unbearable heat of the day, while on African plains, herbivores use the twilight rush hour to eat before nocturnal predators emerge. Every day, a huge rush hour that we don’t even notice takes place in the oceans, as billions of tiny creatures rise to feed, bringing cold water to the surface. When they return to the deep, they take warm water and carbon with them – unlike our rush hour, which causes global warming with carbon emissions, their rush hour helps fight climate change.
