Seeding The environmenT The growth of new structures depends on the introduction of novel material into an environment. Bees distribute pollen from one plant

to another, promoting reproduction in plants. Farmers seed and fertilize soil to enable the growth of selected crops. Oxygen, iron and other heavy elements necessary for the

formation of planets are distributed into interstellar space by supernova explosions.

Bee distributing pollen.

Seeding occurs on very small scales. Flitting from flower to flower as they gath-er nectar to feed the hive, bees move pollen grains from a flower’s male parts to the female parts of the same species, fertilizing the flower and enabling it to reproduce. Pollination by bees and other animals is crucial to the production of most fruits, nuts, and berries on which people and wildlife depend.
