Answer:
Decompression sickness
Nitrogen narcosis
Rapid air consumption
Explanation:
Sea divers can not dive beyond 600 meters from the surface of the sea because of the following :
Decompression sickness
Nitrogen narcosis
Rapid air consumption.
Deep Diving is any dive that is deeper than 20 meters which is 60 feet. However, we there are diverse kinds of diving which gives deep diving its own distinct definition.
In Recreational diving, the maximum depth limit to go is 40 meters which is equivalent to 130 feet
In technical diving, any dive deeper than 60 meters which is equivalent to 200 feet is known as a deep dive.
Decompression sickness : When a diver dive, the air breathe composed of oxygen, nitrogen and other gases. The body uses the oxygen but nitrogen is subsequently released over time since our body does not usually need it. So when pressure suddenly decline or drops, the nitrogen gas which is in the body expands and develops into bubbles. These bubbles are mostly trapped in the joints causing severe pain which is called decompression sickness.
Nitrogen narcosis is experienced when you accumulate too much of nitrogen. The first sign are tingling of the fingers, dizziness and disorientation. It also affects the sight by experiencing a tunnel vision this caused difficulties in reading gauges and instruments. The deeper you dive, the greater the effect of nitrogen narcosis experienced.
Rapid air consumption : The air breathe will become denser as you go deeper due to increasing pressure. Which will subsequently leads to consumption of more air while deep diving as compared to diving at shallower depths

<h2>NATURE IN MY CITY</h2>
________________________
Hello there brainly user! Actually I don't live in city, I'm currently living in a town, where all buildings were made from simple things, like cement, and there are alot of houses in my hometown. My opinion about nature in my hometown is a undescribable feeling. Why? If you are here in my house you can see a mesmerizing mountains, trees and some flowers, I can say that it was really taken care of. Furthermore, nature is valuable in and of itself. This is why Wageningen researchers are working on projects involving threatened animal and plant species in the city, tiny forests, nature-inclusive construction, urban agriculture, and green business parks. “There is lots going on, but there are still substantial barriers.” In addition, Most animals do not like noise, human activity, or disturbances. However, environment and ecology researcher Joost Lahr realised that for roughly 10% of plant and animal species, the city actually serves as a sanctuary.
