Pollen and spores are like dust particles constantly floating in the air and sometimes traveling in the water of rivers, along with the wind and atmosphere's currents but also over birds, insects, and mammals bodies. In their travels, some pollen finds itself in a flower to create seeds, and these seeds will create ecosystems with a unique climate and environment.Some of the pollen and spores will fall over the soils and will create an ecological history record overall times. Like the sand that flows through an hourglass to keep a measure of time, the pollen grains flow through the atmosphere and in the layers of sediment they land to record the time of the earth’s structure. The pollen and spores rain is creating biodiversity and plants flourishing on Earth, it is like stardust that creates the universe. They make up our environment and provides a map of plants existence, like traces in the sand.
