so what do biologists do usually
scientist bit into three main subjects
biology chemistry and physics today is
all about biology biology is the study
of all living things like microorganisms
plants flowers arthropods
fish amphibians reptiles birds and
mammals and that's where we fit in
now this evolutionary list is far bigger
than what I've mentioned and in actual
fact it's a field of biology in itself
but what actually makes something living
well biologists have defined this with
the checklist now in something meets
these criteria bingo you have a living
being
so that chair you're sitting on okay it
may respond to stimuli when you push it
but that's just physics and it most
certainly does not reproduce so in our
table jects like rocks and silver are
left for chemists and physicists now
there's some great videos and what's
considered a living thing I'll leave the
links in the description below
firstly let's dive into some of the
different fields that biologists work in
and how they made an impact here on
earth Earth is not only a place for
humans but for millions of other species
too although we are making incredible
progress by jurists have discovered just
15% of the world species which is just
over and many different individual
living things unfortunately through
human activity we are losing species
faster than we are finding them
effectively removing pages in annex I
clip edia without knowing the contents
on them in order for Earth to continue
to sustain life biodiversity must have
room to flourish now this is where a
zoologist come in they sure that the
full spectrum of the world's organisms
are sustained for future generations
some of the most elegant species on
earth are already endangered and are
facing extinction by studying their
evolution anatomy physiology behavior
and distribution so what are just ensure
that our human activity doesn't affect
them further this means not clearing a
football field worth of forests every
single second as we saw in 2017 in other
words d4
sation similar to this barges
recommendations influence governmental
policy
so when customs ages ask if you're
bringing food or meat produce into the
country is to protect the ecosystem
living there some species from abroad
could completely destroy an ecosystem
but the Asian common toad or the
Japanese knotweed which can destroy in
Thai houses and buildings moving to
marine life what about the amount of
fish you can catch surely there has to
be a limit because without one which
could very quickly become endangered or
even extinct now onto land agriculture
is a big part of biology we humans
depend on the Earth's natural resources
for sustenance so you've got some pretty
good botanists figuring out the best way
to get the most out of our crops and now
we can avoid using pesticides and other
chemicals and some are going beyond
looking at ways to create crops like
heat tolerant wheat that's good news for
some places in the world where the
climate is just so suitable for growing
anything or you could check out what
Mark Watney did when he grew potatoes on
Mars using his own poop now there's some
debate about whether this would work and
that's the beauty of biology it's all
about the research some research looks
at why some animals have a tail or why
we even have a tail bone and whatever
happened to the rest of that tail bone
although this is probably more closely
related to evolution think about the
knowledge and impact it can have on
helping biomedical engineers make
prosthetics for humans like actually
adding a mechanical tail to help those
who struggle to balance or even helping
veterinary scientists allow dogs to walk
again we all know what microorganisms
are things like bacteria viruses or
fungi the interesting part is using
these to help us with our everyday lives
like pharmacologists and immunologists
having doctors to find cures to the
world's deadliest diseases by making
vaccines and antibiotics some biologists
have taken a slightly different approach
finding one of the most important drugs
in modern medicine morphine in a poppy
plant how incredible is that now to
something a little smaller
enzymes some by technologists look at
finding ways to keep your laundry clean
how by adding enzymes which are tiny
protein molecules that boost the rate of
reaction to break up all the bonds
between your clothes on the stains so
just remember this the next time you put
on that nice crispy white shirt that
brings us to where they were and as
you've probably guessed universities
laboratories forests deserts polar
regions jungles artists see pretty much
anywhere there's life but also places
there's no life why well there's a
reason there's no life and we should
know why limited oxygen to hot to cold
by just need to know with all of that
what can we say about it just does or
anything to do the living a tag
biologist is on the case so you know
finding these species helping biomedical
engineers doctors or even understanding
evolution and the origins of life itself
