What is Marine Conservation? | How to Protect Our Oceans

  • 0:07 - 0:11
    Hello and welcome to the
    Natural World Facts Awareness Project.
  • 0:11 - 0:14
    A new series in which I’ll be
    explaining the importance of
  • 0:14 - 0:17
    wildlife conservation and
    what you can do to help.
  • 0:18 - 0:20
    In this video, I’m joined by Alex Collins,
  • 0:20 - 0:23
    a fellow YouTube wildlife
    enthusiast and biologist
  • 0:23 - 0:25
    at the University of Bristol.
  • 0:25 - 0:27
    His channel is linked below,
  • 0:27 - 0:28
    I recommend you check it out
  • 0:28 - 0:31
    for videos on some of the world’s
    rarest species
  • 0:31 - 0:33
    and what you can do to help them.
  • 0:34 - 0:36
    So what is Marine Conservation?
  • 0:36 - 0:40
    Marine Conservation is defined as
    the protection of marine ecosystems,
  • 0:41 - 0:44
    with the focus of limiting the damage
    caused to them by humans
  • 0:44 - 0:47
    and protecting threatened species.
  • 0:47 - 0:51
    The main threats being seen in
    our oceans include species loss,
  • 0:51 - 0:52
    habitat degradation,
  • 0:52 - 0:54
    and changes in ecosystem function.
  • 0:55 - 0:57
    Human activities causing a rise
    in extinction rates
  • 0:58 - 1:01
    has lead to a huge decrease
    in biodiversity,
  • 1:01 - 1:04
    particularly in coral reefs,
    88% of which are threatened
  • 1:04 - 1:06
    by excessive CO2 emissions.
  • 1:07 - 1:11
    These reefs are among the most important
    stores of biodiversity on the planet.
  • 1:12 - 1:15
    It takes around ten thousand years
    for a reef to form from coral polyps,
  • 1:15 - 1:17
    and up to 30 million years for
  • 1:18 - 1:20
    a reef to fully mature,
  • 1:20 - 1:24
    hosting an estimated 25%
    of all marine life.
  • 1:27 - 1:29
    And yet, around the world,
  • 1:29 - 1:31
    coral reefs are dying,
  • 1:31 - 1:34
    as warming temperatures and
    stressful conditions bleach the corals
  • 1:34 - 1:37
    white as they are forced to expel
    the colourful algae
  • 1:37 - 1:40
    on which the coral depends
    for its survival.
  • 1:41 - 1:43
    So, why does this matter?
  • 1:43 - 1:45
    Why is marine conservation
    so important?
  • 1:46 - 1:49
    With the world’s oceans currently
    under more threat than ever before,
  • 1:49 - 1:53
    and with half of the world’s coral reefs
    having died in the last 30 years,
  • 1:53 - 1:55
    marine conservation has never been
  • 1:55 - 1:57
    more important than is today.
  • 1:57 - 1:59
    I’ve already made some videos
  • 1:59 - 2:01
    explaining why conservation is
    so important to you
  • 2:01 - 2:03
    and why we should save
    endangered species
  • 2:04 - 2:06
    So make sure to check
    those videos out after
  • 2:06 - 2:07
    watching this.
  • 2:07 - 2:10
    Put simply, different species rely
    on each other for survival.
  • 2:10 - 2:12
    If one species is under threat,
  • 2:12 - 2:14
    the likelihood is that so
    is another species.
  • 2:15 - 2:16
    This can have a chain reaction, until
  • 2:16 - 2:19
    eventually a whole ecosystem
    is under threat.
  • 2:19 - 2:21
    We need healthy ecosystems
    just as much as
  • 2:21 - 2:23
    the marine life itself,
  • 2:23 - 2:26
    because without them,
    we’d have less food, less money,
  • 2:26 - 2:29
    and with altogether less life
    on our planet.
  • 2:29 - 2:31
    The bottom line is Earth needs
    healthy oceans, and it is our
  • 2:32 - 2:34
    responsibility to protect them.
  • 2:34 - 2:36
    So how can we do this?
  • 2:36 - 2:40
    One of the most effective methods has been
    the setting up of marine protected areas.
  • 2:41 - 2:43
    This creates a much safer environment
    for marine life,
  • 2:44 - 2:45
    undisturbed by the impacts of overfishing,
  • 2:45 - 2:49
    noise pollution from ships, and
    other human activities.
  • 2:50 - 2:56
    Thankfully, biodiversity has been found to increase
    by 21% within marine reserves like these.
  • 2:56 - 2:58
    We can also use artificial reefs.
  • 2:58 - 3:01
    These are man-made structures,
    built to promote marine life
  • 3:01 - 3:03
    and the growth of new coral.
  • 3:03 - 3:06
    Artificial reefs have proven successful
    in providing a habitat for threatened wildlife,
  • 3:08 - 3:10
    These allow damaged ecosystems to recover
  • 3:10 - 3:13
    and valuable biodiversity to regenerate.
  • 3:13 - 3:16
    As well as these strategies, we also
    need to be careful in the way
  • 3:16 - 3:18
    we interact with the marine environment.
  • 3:18 - 3:21
    Active demersal fishing techniques,
    like trawling,
  • 3:22 - 3:24
    where a net is dragged along
    the bottom of sea floor,
  • 3:24 - 3:26
    can be really destructive
  • 3:26 - 3:30
    as this destroy ecologically important
    species like certain corals.
  • 3:30 - 3:34
    Active pelagic fishing techniques, where a
    net is dragged through the open ocean,
  • 3:34 - 3:36
    can also be just as bad.
  • 3:36 - 3:38
    This is because that it’s indiscriminate,
    meaning that
  • 3:38 - 3:40
    they catch anything in their way of net,
  • 3:40 - 3:42
    regardless of whether
    the fisherman want it or not.
  • 3:42 - 3:47
    This often leads to protected animals
    like dolphins and turtles being injured
  • 3:47 - 3:51
    or killed. For every 1 kilogram of prawns
    that are caught and sold in stores,
  • 3:52 - 3:54
    nine kilograms of other sea animals
    are caught as bycatch,
  • 3:54 - 3:57
    being injured or killed and
    then thrown away.
  • 3:57 - 4:00
    Marine conservation efforts have been
    made to reduce the destruction
  • 4:00 - 4:02
    caused by these fishing techniques,
  • 4:02 - 4:05
    either by reducing the amount of time
    of these techniques are allowed to be used
  • 4:06 - 4:08
    or making the technique itself
    less destructive.
  • 4:09 - 4:12
    One example of this, is to use
    specific fishing hooks which
  • 4:12 - 4:15
    are less likely to catch unwanted species.
  • 4:15 - 4:17
    Solving these problems does
    take a lot of hard work,
  • 4:17 - 4:19
    but that doesn’t mean
    there’s nothing that you can do
  • 4:20 - 4:21
    if you don’t work as a conservationist.
  • 4:22 - 4:26
    So here are some other things that you can
    do to help marine conservation.
  • 4:27 - 4:29
    Firstly, use your water supply
    more economically.
  • 4:29 - 4:32
    This will not only save you money, but it will
  • 4:32 - 4:37
    also reduce excess runoff, containing
    pollutants and waste into the ocean.
  • 4:37 - 4:39
    Secondly, use less energy in your daily life.
  • 4:39 - 4:41
    Higher temperatures can cause the death
  • 4:41 - 4:45
    of corals, rising sea levels and flooding,
  • 4:45 - 4:48
    and more extreme weather which
    can damage marine ecosystems.
  • 4:49 - 4:52
    Many marine species also rely on
    specific temperatures to determine
  • 4:52 - 4:54
    what sex they develop into.
  • 4:54 - 4:57
    This is called temperature-dependent
    sex determination,
  • 4:57 - 5:02
    and so by changing the temperature we can
    throw an entire population out of balance.
  • 5:02 - 5:05
    You can also fish more responsibly,
  • 5:05 - 5:08
    or just fish less, or not at all if that is
    an option to you.
  • 5:08 - 5:10
    The same goes for eating seafood.
  • 5:10 - 5:13
    Reducing your use of plastics
    is also essential.
  • 5:13 - 5:15
    Ingestion of microplastics, bits of plastic
  • 5:16 - 5:20
    which are less than 5mm across,
    can lead to bioaccumulation.
  • 5:20 - 5:22
    This is where harmful substances
  • 5:22 - 5:25
    build up in the food chain and eventually
    cause serious damage
  • 5:25 - 5:27
    to the species at the top.
  • 5:28 - 5:30
    There are just a few things
    that you should consider
  • 5:30 - 5:32
    when trying to cause less impact
    to marine life.
  • 5:32 - 5:36
    There are of course plenty
    of other things that you can do to help.
  • 5:36 - 5:38
    So if you’d like to know more,
  • 5:38 - 5:39
    then let us know down in the comments,
  • 5:39 - 5:42
    so that we can make another video for you.
