What If Every Plant on Earth Dried Up?

Imagine waking up to a planet where every leaf has turned to paper. Forests, crops, lawns, algae, and phytoplankton have stopped functioning. Would humans suffocate immediately—or would the food system collapse first? This four-minute whiteboard science story follows the chain reaction: photosynthesis stops, food reserves become a countdown, food webs unravel, the water cycle loses a biological link, and the atmosphere slowly becomes less balanced. The key twist is that oxygen is not the first crisis. The first crisis is the loss of new food. #Science #Educational #Photosynthesis #Ecosystems #ClimateScience #Biology #WhatIf
