What is Marine Conservation? | How to Protect Our Oceans

  • 0:08 - 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
  • 0:14 - 0:17
    the importance of 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 - 1:25
    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 more under
    threat than ever before,
  • 1:49 - 1:52
    and with half of
  • 1:53 - 1:55
    the world’s reefs having died in the last
    30 years, Marine Conservation has never been
  • 1:55 - 1:57
    more important than today.
  • 1:57 - 1:59
    I’ve already made some videos which answer
    these questions on my own channel, so if you’d
  • 1:59 - 2:02
    like to know why conservation is crucial to
    both yourself and the environment, and why
  • 2:02 - 2:06
    we should save endangered species and ecosystems,
    then make sure to check those videos out after
  • 2:06 - 2:07
    you’ve finished watching this.
  • 2:07 - 2:11
    Put simply, different species rely on each
    other for survival. If one species is under
  • 2:11 - 2:16
    threat, the likelihood is that so is another
    species. This can have a chain reaction, until
  • 2:16 - 2:21
    eventually a whole ecosystem is under threat.
    We need healthy ecosystems just as much as
  • 2:21 - 2:27
    the marine life itself, because without them,
    we’d have less food, less money, and less
  • 2:27 - 2:32
    life on our planet. The bottom line is, life
    on 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 - 2:41
    One of the most effective methods has been
    the setting up of marine protected areas.
  • 2:41 - 2:45
    This creates a much safer environment for
    marine life, undisturbed by the impacts of
  • 2:45 - 2:51
    overfishing, noise pollution from ships, and
    other human activities. Thankfully, biodiversity
  • 2:51 - 2:56
    has been found to increase by 21% within marine
    reserves like these.
  • 2:56 - 3:00
    We can also use artificial reefs. These are
    man-made structures, built to promote marine
  • 3:00 - 3:05
    life and the growth of new coral. Artificial
    reefs have proven successful in providing
  • 3:05 - 3:10
    a habitat for threatened wildlife, therefore
    allowing damaged ecosystems to recover, and
  • 3:10 - 3:13
    the regeneration of valuable biodiversity
    within reef ecosystems.
  • 3:13 - 3:17
    As well as these strategies, we also need
    to be careful in the way we interact with
  • 3:17 - 3:21
    the marine environment. For example, active
    demersal fishing techniques like trawling,
  • 3:21 - 3:26
    where a net is dragged along the bottom of
    the ocean, can destroy the seafloor, which
  • 3:26 - 3:30
    often contains ecologically important plant
    and coral species.
  • 3:30 - 3:34
    Active pelagic fishing techniques, where a
    net is dragged through the open ocean, can
  • 3:34 - 3:38
    also be just as bad. This is because it’s
    indiscriminate, meaning that the nets will
  • 3:38 - 3:42
    catch anything in their way, regardless of
    whether or not the fisherman are looking for
  • 3:42 - 3:47
    it. This often leads to protected animals
    like dolphins and turtles being injured or
  • 3:47 - 3:52
    even killed. For every 1 kilogram of prawns
    that are caught and sold in stores, 9 kilograms
  • 3:52 - 3:57
    of other sea animals are caught as bycatch,
    being injured or killed and then thrown away.
  • 3:57 - 4:01
    Marine conservation efforts have been made
    to reduce the destruction caused by these
  • 4:01 - 4:06
    fishing techniques, either by reducing how
    often they are allowed to be used, or by making
  • 4:06 - 4:12
    the technique itself less destructive. For
    example, by using specific fishing hooks that
  • 4:12 - 4:14
    are less likely to catch unwanted species.
  • 4:14 - 4:15
    So there’s a small insight into just some
    of the problems that marine conservationists
  • 4:15 - 4:18
    face today. Solving these problems does take
    a lot of hard work, but that doesn’t mean
  • 4:18 - 4:22
    there’s nothing you can do if you don’t
    work as a conservationist.
  • 4:22 - 4:26
    So here are some simple things that you can
    do to help marine conservation.
  • 4:26 - 4:32
    Firstly, use your water supply more economically.
    This will not only save you money but it will
  • 4:32 - 4:37
    reduce excess runoff, containing pollutants
    and waste, into the ocean.
  • 4:37 - 4:41
    Secondly, use less energy in your day to day
    life. Higher temperatures can cause the death
  • 4:41 - 4:46
    of corals, rising sea levels and flooding,
    and more extreme weather which can damage
  • 4:46 - 4:52
    marine ecosystems. Many marine species also
    rely on specific temperatures to determine
  • 4:52 - 4:56
    what sex they develop into (i.e. they have
    temperature-dependent sex determination),
  • 4:56 - 5:02
    and so by changing the temperature we can
    throw an entire population out of balance.
  • 5:02 - 5:08
    You can also fish responsibly, or just fish
    less, or not at all if this is an option to
  • 5:08 - 5:11
    you. The same goes for eating seafood.
  • 5:11 - 5:16
    Reducing your use of plastics is also essential.
    Ingestion of microplastics (bits of plastic
  • 5:16 - 5:22
    which are less than 5mm across) can lead to
    bioaccumulation. This is where harmful substances
  • 5:22 - 5:27
    build up in the food chain and eventually
    cause serious problems to the organisms at
  • 5:27 - 5:28
    the top.
  • 5:28 - 5:31
    There are just a few things that you should
    consider when trying to cause less impact
  • 5:31 - 5:36
    to marine life. There is of course plenty
    of other things that you can do to help, so
  • 5:36 - 5:40
    if you’d like to know more, then let us
    know down in the comments, and we can make
  • 5:40 - 5:45
    another video for you.
