Oil is "acutely lethal" to fish - that is, it kills fish quickly, at a concentration of 4000 parts per million [25] (0.4%). The toxicity of petroleum related products threaten human health. Many compounds found in oil are highly toxic and can cause cancer (carcinogenic) as well as other diseases. [23]
Earth's natural oil supply is effectively fixed because petroleum is naturally formed far too slowly to be replaced at the rate at which it is being extracted. Over many millions of years, plankton, bacteria, and other plant and animal matter became buried in sediments on the ocean floor.
This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals. Examples of biological hazards include bacteria, viruses, fungi, other microorganisms and their associated toxins.

The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
Oil prices plunged to their lowest level since December 2021, with Brent oil falling 4% to $68.99 on Tuesday. Supply and demand issues, including a slowdown in China's economy, are pressuring prices.
The exaerobic zone is found at the boundary of anoxic and hypoxic zones. Hypoxia can occur throughout the water column and also at high altitudes as well as near sediments on the bottom. It usually extends throughout 20–50% of the water column, but depends on the water depth and location of pycnoclines (rapid changes in water density with depth).
