Prove that the conditions for the existence of organisms in the ocean are more favorable than on land

Organisms are much easier to live in the ocean, even because there the degree of influence of external stimuli is much less. Water smoothes out the aggressive effects of light, dust and chemicals, which are much easier to carry through the air. In addition, due to the greater density of water, it keeps one temperature much longer, when the air can be heated and cooled in a short period of time, which can seriously complicate the life of any organisms, because the constancy of the environment is the main guarantee of a stable and prosperous life.
