Explanation:

There is a widespread theory that tries to explain that the fish left the water for vital needs. A period of droughts was established that greatly diminished their habitats, so that the individuals that moved and adapted were those that could survive. However, this theory is not very well supported, because there is no evidence of these droughts in the geological moments when these animals left the waters, nor is it believed that this cause alone could generate so many evolutionary changes. Today, more is bet on the stimulus that would be offered by the opportunities offered by the mainland.

The aquatic environment was stressful, it was overpopulated and presented all kinds of dangers, while the terrestrial one was much safer, it was almost depopulated and the resources were practically infinite, ready to be used by the first to arrive, without any competition, for that reason they did it.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
