Do endangered species have shorter life expectancies than from before they were endangered?

Not necessarily on a physiological basis. 'Life expectancy' is an expected age that an organism should attain in its natural environment. Although some may have a reduced life expectancy due to affected physiology such as chemical contamination from fertiliser usage, the majority of endangered species are endangered because they are killed by humans or they die because of survival pressures placed upon them due to habitat threatening due to human influence...it is these and other such factors that reduce their likelihood to live to their expected age, but this is not 'life expectancy'.

First and foremost, womyn need their reproduction rights. Abortion is such a heated subject, but without giving womyn the right to have abortions then they could end up killing them selves also as they used to so much by using things like hangers or other awful ways. WOMYN NEED THE FREEDOM OF THEIR OWN BODIES. When that is also controlled by men, it keeps those sexist and patriarchy roles in place. Do some fem. research before comparing womyn's freedom to endangered plants.

If the reduced number forced them to become inbred. Life expectancies for individuals will be reduced due to the general reduction of vigour for the individual organisms.
