One of the main causes of environmental issues is population increase, which calls for an increasing amount of (non-renewable) resources for its own needs.

The prevalence of disease was significantly reduced by massive advances in hygiene brought about by the availability of clean water sources and reticulated sewage systems to eliminate waste.

As a result, life expectancy has significantly increased, which affects population numbers. If everyone survived to the age of 30, there would be half as many people on the earth.

The rapid expansion of our population is also a result of medical advancements, which, coupled with improved hygiene, have increased the likelihood that women and children will survive delivery and that most infants will grow up.

In addition, the development of medicines and vaccinations has significantly reduced the prevalence of disease, particularly infectious disease.
For instance, vaccination has eradicated smallpox, which once claimed the lives of millions of people.
And because to antibiotics, we can now control basic bacterial illnesses that used to kill individuals within a week of getting scratched by a rose thorn while gardening.
