One more reason to care for plants: those that bloom, cool the planet and refresh it.

That is at least the results of a climate model published in Proceedings of the Royal Society B. The effect is more notorius in the Amazon basin, where flowering plants replacement with the ones that do not blosom mean losing 80 percent of the area covered by rainforest.

The simulations showed the importance of the physiology of these plants in regulating the climate in forested regions, said C. Kevin Obice, author of the study, areas where the dry season is short or nonexistent and where most biodiversity occurs.

This is of physiological importance for the sequestration of carbon dioxide from the atmosphere for photosynthesis and water loss or transpiration.

This high density of veins in the leaves means that these plants are very efficient to transpire soil water back into the atmosphere, where you can go back to the ground as rain.

This process depends on the transpiration, which is much lower in the absence of flowering plants.

During most of Earth’s history there were no flowering plants known as angiosperms. Evolved about 120 million years ago during the Cretaceous and took another 20 million years to be the dominator.

The species with flowers are a late product of vascular plants, a group that includes ferns, but now dominate the world.
