Plants Are World Travelers
We think of plants as stationary life forms anchored to the soil, but National Geographic News reminds us that they have remarkable ways of getting around via seed dispersal mechanisms. Some fly through the air with parachutes or helicopters, some float in the water, and some rely on animals. It appears that some exotic species may be vanishing because animals they relied on for dispersal have gone extinct.
A wonderful film that reveals the hidden world of seed dispersal is the award-winning Moody science classic Journey of Life. This is a must-see nature film. Follow delicate packages of life as they travel through the air, across oceans and continents, down rivers, through fires, ride on birds and monkeys and cows, roll through the West, explode across the field and even crawl across the soil and drill themselves in the ground. The time-lapse and slow-motion photography is stunning. This “sermons from science” film ends with an analogy to another seed spoken of by the Lord Jesus in one of his parables: the word of God. The film would make a great introduction or conclusion to a local nature hike.
