What was a challenge faced by early ocean explorers?
The unsanitary conditions could lead to a rapid spread of disease. Provisions were also a concern, without any clear idea of where they were going provisions could run short and the poor diet could lead to malnutrition or scurvy, which is caused by a lack of vitamin C.
What is the main obstacle to exploring the ocean depths?
Three main obstacles have kept us from studying the depths of the ocean: absence of light, very cold temperatures, and high pressure. As you know, light only penetrates the top 200 meters of the ocean; the depths of the ocean can be as much as 11,000 meters deep.
What is the biggest scientific issue for ocean exploration?
Darkness, cold, and crushing pressures have challenged the most experienced engineers to develop submersibles that descend to seafloor depths that are not safe for divers, allowing us to explore the deep ocean firsthand.
Why is ocean exploration better than space exploration?
With space exploration, scientists can see everything that’s in front of them, using telescopes. With ocean exploration, we’re can’t see very far. Light doesn’t permeate deep into open water. In fact, it’s easier to send a person to space than it is to send one down to the bottom of the deepest part of the ocean.
Is exploration worth the risk?
Exploration can lead to advances in science and medicine, and will improve safety and help us combat everyday hazards. Because major exploration will help improve safety, it proves further that exploration is worth the risk.
What are some dangers of exploration?
Even ‘everyday exploration’ without boundaries and other precautions can be dangerous. One can just drift – read books, surf the internet aimlessly, travel, jump from one relationship or brief fling to another and avoid ‘real life’ problems… It is important to ensure your physical and other needs are met.
What are the risks of exploring space?
5 Hazards of Human Spaceflight
- Radiation.
- Isolation and confinement.
- Distance from Earth.
- Gravity (or lack thereof)
- Hostile/closed environments.
- Human research essential to space exploration.
Why do astronauts risk their lives?
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
What happens if you drank pee?
When urine passes through the urinary tract, it becomes contaminated with bacteria. Drinking urine, whether your own or someone else’s, introduces bacteria into your system that can cause gastrointestinal problems or other infections.
