Zusammenfassung

TLDRThe video discusses biodiversity, which encompasses the variety of living organisms that support ecosystems. Key threats to biodiversity include climate change, habitat loss, pollution, invasive species, and over-exploitation. Climate change impacts species and ecosystems significantly, while habitat loss due to natural and human-induced changes leads to displacement of organisms. Various forms of pollution threaten life forms, particularly through nutrient imbalances. Invasive species disrupt ecosystems by dominating habitats, and over-exploitation through activities like overfishing diminishes species diversity. The video advocates for increased awareness and engagement in conservation efforts to protect biodiversity.

    The video discusses biodiversity, which encompasses the variety of living organisms including plants, animals, bacteria, and humans, and how it supports ecological functions like providing oxygen and clean water. It then identifies threats to biodiversity, starting with climate change, which leads to long-term effects on population distribution and ecosystem functionality. Habitat loss and degradation follow as a significant threat due to natural disasters and human activities like deforestation, displacing organisms and reducing biodiversity. Pollution in its various forms, particularly nutrient pollution, poses another risk to biodiversity. Invasive species, characterized by their adaptability and capability to dominate, threaten native species and habitats. Lastly, over-exploitation through activities like overfishing leads to lower species diversity, increasing the risk of extinction. The video concludes by urging viewers to participate in biodiversity conservation through education, awareness, and support for policies that protect ecosystems.

    in this video we are going to tackle the
  • 00:00:03
    threats to biodiversity
  • 00:00:05
    [Music]
  • 00:00:06
    but before that what is biodiversity
  • 00:00:09
    exactly
  • 00:00:11
    biodiversity talks about the variety of
  • 00:00:13
    living organisms
  • 00:00:15
    it also brings together the different
  • 00:00:17
    species and forms of life
  • 00:00:19
    including plants bacteria animals and of
  • 00:00:23
    course
  • 00:00:23
    human for ecological support
  • 00:00:28
    biodiversity provides functioning
  • 00:00:30
    ecosystems that supply
  • 00:00:32
    oxygen clean air and water pollination
  • 00:00:35
    of
  • 00:00:35
    plants pest control waste water
  • 00:00:39
    treatment
  • 00:00:39
    and many ecosystem services
  • 00:00:42
    so now let's talk about the threats to
  • 00:00:45
    biodiversity
  • 00:00:47
    so first is the climate change climate
  • 00:00:50
    change refers to the long-term and
  • 00:00:52
    irrevisible change that occurs in the
  • 00:00:54
    earth's climate
  • 00:00:55
    this increase in the temperature of the
  • 00:00:57
    atmosphere has major effects on the
  • 00:01:00
    environment
  • 00:01:01
    such as the seasons rising of the sea
  • 00:01:03
    levels and glacial retreats
  • 00:01:05
    a biodiversity of organisms are affected
  • 00:01:08
    regarding their population
  • 00:01:10
    distribution level of ecosystem
  • 00:01:14
    and even the individual's morphology and
  • 00:01:16
    function
  • 00:01:18
    next is the habitat loss and degradation
  • 00:01:21
    habitat loss refers to the changes in
  • 00:01:23
    the environment
  • 00:01:24
    that results to the rendering of the
  • 00:01:26
    specific habitat to be functionally
  • 00:01:28
    available so what are the costs of
  • 00:01:31
    habitat loss
  • 00:01:33
    these are natural calamities geological
  • 00:01:36
    events
  • 00:01:37
    anthropogenic activities like
  • 00:01:39
    deforestation
  • 00:01:40
    and man-induced climate change
  • 00:01:43
    in the process of habitat degradation
  • 00:01:46
    the organisms that were once living in a
  • 00:01:48
    particular area or region
  • 00:01:50
    are displaced and are forced to relocate
  • 00:01:52
    thus resulting in biodiversity or
  • 00:01:55
    reduction
  • 00:01:56
    the third threats to biodiversity is the
  • 00:01:59
    pollution
  • 00:02:01
    field water air or land pollution
  • 00:02:04
    all forms of pollution appear to be a
  • 00:02:07
    threat to all life forms on earth
  • 00:02:10
    however it plays a major threat to
  • 00:02:12
    biodiversity
  • 00:02:13
    when it comes to the nutrient slowly of
  • 00:02:15
    the elements nitrogen and phosphorus
  • 00:02:18
    next to habitat loss invasive species
  • 00:02:21
    are around as the second biggest threat
  • 00:02:23
    to biodiversity
  • 00:02:24
    the greatest threat that the invasive
  • 00:02:26
    species can bring is their capability to
  • 00:02:28
    change an entire habitat
  • 00:02:30
    these species are highly adaptable and
  • 00:02:32
    can easily dominate a certain area
  • 00:02:35
    because many natural species survive
  • 00:02:37
    only in a particular environment
  • 00:02:39
    they tend to be displaced or worse
  • 00:02:41
    perish
  • 00:02:42
    lastly is the over-exploitation
  • 00:02:45
    over-harvesting
  • 00:02:47
    overfishing and over-hunting are some
  • 00:02:49
    examples of overexploitation
  • 00:02:52
    so as population or ecosystem continues
  • 00:02:55
    to suffer from low species diversity
  • 00:02:57
    the probability of getting wiped out
  • 00:02:59
    completely when a natural disaster or
  • 00:03:02
    other forces increases
  • 00:03:05
    so what can we do now let us participate
  • 00:03:09
    in biodiversity conservation
  • 00:03:11
    by increasing our knowledge of
  • 00:03:13
    environmental issues
  • 00:03:14
    increasing our awareness of the impacts
  • 00:03:16
    of biodiversity
  • 00:03:18
    laws and increasing support for
  • 00:03:20
    government policies
  • 00:03:21
    and actions that conserve our valuable
  • 00:03:23
    ecosystem
  • 00:03:25
    we can become educators and role models
  • 00:03:28
    as towers of the environment by aiding
  • 00:03:31
    the recovery of species at risk
  • 00:03:33
    and preventing other species from
  • 00:03:35
    becoming at risk
