Have you ever been underwater?   Scuba divers carry their own source of breathing gas,
yes i like scuba diving
Unfortunately, Immersion in water and exposure to high ambient pressure have physiological effects
wow i havent been that deep before
 Humans are not physiologically and anatomically well adapted to the environmental conditions of diving
thats why i always wanted to be a fish, i love water
One way to enjoy is  Ecology (from , "house", or "environment"; -λογία, "study of") the scientific study of interactions
interesting
: physical science and life science (or biological science).
- Social sciences: the study of human behavior and societies.
Natural and social sciences are empirical sciences, meaning that the knowledge must be based on observable phenomena and must be capable of being verified by other researchers working under the same conditions. This verifiability may well vary even "within" a scientific discipline
Natural, social, and formal science make up the fundamental sciences, which form the basis of interdisciplinary and applied sciences such as engineering and medicine
Underwater diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment.
Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done.
In ambient pressure diving, the
