Each year, an estimated 23,000 people die
from Antibiotic Resistant Infections.
Bacteria can become resistant to antibiotics overtime.
Everytime a person takes antibiotics, sensitive bacteria are killed,
but resistant germs may be left to grow and multiply. Repeated
and improper uses of antibiotics are primary causes of the increase in drug
This topic can relate to the peppered moths as of how they have adapted
to living in a dark environment through natural selection. These
Heritable genetic vaiation.

four components consist of:
"Peppered Moth and Natural Selection - Moths Count"
Individuals with charateristics which increase their probability of
survival will have more opportunities to reproduce and their offspring
will also benefit from the heritable, advantageous character.
So over time these variants will spread through the population.
Just like the peppered moths, the dark ones were able to
give dark/good traits to their offspring, giving them a better chance to survive.
"Evolution in Color: From Peppered Moths to Walking Sticks."
During competition, these bacteria have few to none competitor bacterias which gives them access to more resources. With less competition, and an abundant of resources, this gives the bacteria a chance to reproduce much more compared to others that lack in resources. Just like the resistant bacterias, it was able to resist against the antibiotics. This leaves the resistant bacterias a chance to reproduce more bacterias with resistant genes.
The survival of organisms that are better fit in a changing environment is the most important factor for the overall population of natural selection because the camoflauged moths/dark ones had a better chance to live and survive compared to the light moths which didn't blend in to the dark environment giving predators an easier chance to snatch and kill the light moths. This leaves dark moths to reproduce giving these traits to its offsprings.
