Can we drink ocean water?

Drinking seawater can be deadly to humans. Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.

What year will we run out of oxygen?

Based on NASA’s calculation that a human needs 840 grams of oxygen per day, and the fact that Earth’s atmosphere contains about 1000 billion tonnes of oxygen and the global population is 7.5 billion, it would last around 370 years.

Why do we not run out of oxygen?

With so many organisms breathing in and using oxygen how is it that we never run out? Short answer: It is because oxygen is continuously regenerated by organisms that employ photosynthesis, which use residuals from respiring organisms (carbon dioxide and water) to synthesize carbohydrates (sugars) …
