|Why do all living things die?|
The reson for the death of all living things is
not clear. However, what is clear is that death
is an important part of life and it is the
last step in the circle of life. Ever since the
date of brith, living things start to use all ways
to survive but not to die. They compete with each
other for food and other resources that can make
them live longer. The reason for the death for
individual of the living things can be different.
For example, human beings die because of serious
illnesses, accidents and so on. Death is just a
circle of life and all living things has to
undergo the circle of life.
Every living thing know to exist has so far
been known to die or at least replace most of its
cells. I don't think it is fully understood
why some living things age and die faster then
others. But living lines are made up of living
cells that often die faster than the organisms as
a whole because the organisms can replace some of
the cells as they age and die. But typically, an
organisms ability to replace the cells
deteriorates with time so that eventually the
whole organism dies.
There is something in physics called
"entropy", which is a measure of the
disorder in something. One of the laws of
physics (the second law of thermodynamics) states
that entropy is indestructible: you can move it,
you can make more of it, but you can never get rid
of it other than by putting it somewhere else.Living things are highly ordered,
low-entropy things In order to live, we have
to create more entropy elsewhere. However, this
also means that if our own order is disrupted or
destroyed, we die, and because entropy cannot be
unmade, death is almost always permanent.
DNA (the blueprints for our cells) can only
handle so many replications because we lose info
every time, telomeres get shorter, but
there is theoretical research in medicine to
preserve telomere length.
Everything wears out as it gets older. When
living things get too worn out to stay alive, they
