The legislation authorized Medicine Chest be carried on every American Flag vessel of more than 150 tons back in the 1700's, so long as it had a crew of ten or more. A loose network of marine hospitals, primarily in port cities, was established by Congress to care for disabled and sick American merchant seamen around 1798. Federal entities, namely, the Marine Hospital Service, the Public Health and Marine Hospital Service, and lastly the Public Health Service continued to give healthcare to merchant seamen until 1981. The Medical Aid at Sea and Ship's Medicine Chest has been a part of much of this maritime history.
Based on the data provided, we can conclude that the graph in question corresponds to the K-selected theory in regards to the human species.
When considering the data of certain species and grouping them into categories such as extinct, endangered, or K/r-selected we take into account factors such as:
- Population size
- Behavior
- Carrying capacity
- Reproduction rates
and so on, then classify each species accordingly.
Species that are Extinct are no longer on the earth. This classification refers to species of the past and does not include humans as of yet. The endangered category is reserved for species whose population sizes are <u>at a critical low and are near </u><u>extinction</u>, which is also not the case for humans.
The K-selected and r-selected theories consider reproduction rates and carrying capacity as well when grouping species. Species that produce few offspring at a time are often found in this group. This category also refers to species whose offspring have a high chance of survival into maturity and whose population size is near the limit of the environment. All of this follows the data given and is the classification for the human species.
