TLDRThe video explains deforestation, the removal of trees and forests for various land uses, and its global prevalence. It highlights the importance of trees in carbon cycling, as they absorb carbon dioxide and release oxygen. Deforestation leads to increased carbon dioxide in the atmosphere, contributing to global warming. It also affects local climates by altering albedo and disrupting precipitation patterns. The video suggests solutions such as selective logging, protecting sensitive areas, and individual actions like reducing, reusing, and recycling to mitigate deforestation's impact.

    Deforestation, the removal of trees and forests for land use and wood resources, is a growing issue globally. It affects our daily lives as many products, from furniture to paper, come from trees. Despite the vast amount of trees on Earth, we are losing them at an alarming rate, roughly 36 football fields per minute. This deforestation impacts climate and ecosystems significantly. Trees play a crucial role in carbon cycling; they absorb carbon dioxide and release oxygen. When trees are cut down, not only is this balance disrupted, leading to increased carbon dioxide in the atmosphere—one of the greenhouse gases contributing to global warming—but the process also affects local climates, reflecting a need to understand the intricacies of such environmental changes.

  • 00:00:00
    deforestation is the process of removing
  • 00:00:02
    trees and forests from a landscape this
  • 00:00:05
    may be done for many reasons including
  • 00:00:07
    making way for other land uses such as
  • 00:00:09
    Agriculture and also to harvest for wood
  • 00:00:12
    resources although it might not be
  • 00:00:14
    something you see or hear about every
  • 00:00:16
    day deforestation is a problem that is
  • 00:00:18
    happening all over the world and has
  • 00:00:20
    been for many years you might be
  • 00:00:22
    wondering how does this affect me why
  • 00:00:25
    should I care well think about the desk
  • 00:00:27
    that you're sitting at and the pencil
  • 00:00:29
    and paper you're writing with along with
  • 00:00:31
    the majority of the furniture you use at
  • 00:00:32
    home what do they all have in
  • 00:00:35
    common they're all made from trees we
  • 00:00:38
    use trees to make a lot of different
  • 00:00:40
    products that we use every single day
  • 00:00:42
    which means we have to cut down a lot of
  • 00:00:44
    trees to make them so now you may be
  • 00:00:47
    thinking well why should I care there
  • 00:00:49
    are lots of trees and Forest on Earth
  • 00:00:51
    it's true there are a lot of trees on
  • 00:00:53
    Earth in fact Forest covers a quarter of
  • 00:00:56
    all land surfaces on Earth
  • 00:01:00
    but the problem is the rate at which we
  • 00:01:02
    Harvest them currently humans are
  • 00:01:04
    cutting down forests at a rate of 36
  • 00:01:06
    football fields per
  • 00:01:07
    [Music]
  • 00:01:09
    minute deforestation affects many
  • 00:01:11
    ecosystem functions but the question
  • 00:01:13
    we're asking in this video is how does
  • 00:01:16
    this affect the
  • 00:01:17
    climate first off let's talk about
  • 00:01:19
    carbon cycling think about how you
  • 00:01:21
    breathe you breathe in oxygen and you
  • 00:01:25
    breathe out carbon
  • 00:01:27
    dioxide plants and trees do the opposite
  • 00:01:30
    they absorb carbon dioxide and release
  • 00:01:33
    oxygen through a process called
  • 00:01:36
    photosynthesis when we cut down large
  • 00:01:38
    amounts of trees carbon dioxide is no
  • 00:01:41
    longer absorbed and it stays in the
  • 00:01:43
    atmosphere this is a problem because
  • 00:01:46
    carbon dioxide acts as a greenhouse gas
  • 00:01:49
    this means it acts like a greenhouse by
  • 00:01:51
    absorbing and re-emitting radiation back
  • 00:01:54
    down to earth we further contribute to
  • 00:01:56
    this when we burn Forest materials
  • 00:01:58
    because the carbon storage in them is
  • 00:02:00
    then released into the atmosphere
  • 00:02:02
    greenhouse gases have a warming effect
  • 00:02:04
    and because large amounts are being
  • 00:02:06
    released into the atmosphere all around
  • 00:02:08
    the world they are having a global
  • 00:02:10
    warming effect on the local scale
  • 00:02:13
    however deforestation is having a
  • 00:02:15
    different effect first let's talk about
  • 00:02:17
    albo the albo is the amount of light
  • 00:02:20
    that is reflected off a surface the main
  • 00:02:22
    control of albo is a surface's color
  • 00:02:26
    picture a black car in the Sun dark
  • 00:02:28
    colors absorb most of the light which is
  • 00:02:30
    why black cars get so hot on a sunny day
  • 00:02:33
    white reflects light which is why white
  • 00:02:36
    cars don't heat up as
  • 00:02:37
    much the same is true with land a dark
  • 00:02:41
    surface such as Forest cover will absorb
  • 00:02:44
    light while a bare surface such as grass
  • 00:02:47
    will reflect more this causes a local
  • 00:02:49
    cooling
  • 00:02:51
    effect precipitation patterns are also
  • 00:02:54
    affected by
  • 00:02:55
    deforestation when it rains plants and
  • 00:02:58
    trees absorb water through transpiration
  • 00:03:01
    plants lose water which is evaporated
  • 00:03:03
    into the atmosphere clouds form from the
  • 00:03:06
    evaporated water and when enough is
  • 00:03:08
    collected it begins to rain the cycle
  • 00:03:10
    then repeats
  • 00:03:12
    itself however the cycle is disrupted
  • 00:03:15
    when deforestation occurs when it rains
  • 00:03:18
    there are no trees left to uptake the
  • 00:03:19
    water so most of the Fallen rain
  • 00:03:22
    collects and moves off the surface as
  • 00:03:24
    runoff this means that little water is
  • 00:03:26
    left to be evaporated which means
  • 00:03:28
    there's a smaller contra contribution
  • 00:03:30
    towards the formation of clouds and Rain
  • 00:03:32
    eventually this degrades the environment
  • 00:03:35
    because it's lacking the water that it
  • 00:03:37
    needs deforestation has many negative
  • 00:03:39
    impacts on the environment but it can't
  • 00:03:42
    be completely stopped because humans
  • 00:03:43
    rely on it so heavily so what can we do
  • 00:03:47
    one way to fix this problem is to change
  • 00:03:49
    how we Harvest trees instead of cutting
  • 00:03:52
    down every single tree we can
  • 00:03:53
    selectively choose trees to cut and
  • 00:03:56
    leave others try and help maintain some
  • 00:03:58
    of the ecosystem functions
  • 00:04:01
    protecting and conserving ecologically
  • 00:04:03
    sensitive areas is another way to
  • 00:04:05
    decrease impacts of deforestation by
  • 00:04:07
    selectively choosing regions we can
  • 00:04:09
    conserve old growth forests and also
  • 00:04:11
    protect endangered species
  • 00:04:14
    habitats you can make a difference too
  • 00:04:17
    just follow the three Rs the first one
  • 00:04:19
    is reduce this means using less whether
  • 00:04:23
    that be paper tissue or even toothpicks
  • 00:04:26
    just try to use less the next one is
  • 00:04:29
    reused this one is easy and can save you
  • 00:04:31
    money for example use reusable
  • 00:04:34
    containers and cups instead of
  • 00:04:35
    disposable ones another example is to
  • 00:04:38
    reuse old furniture or pass it on to
  • 00:04:40
    someone
  • 00:04:41
    else and lastly the third R is recycle
  • 00:04:45
    this means disposing of waste properly
  • 00:04:48
    make sure recyclable items go into the
  • 00:04:50
    correct bins so that they can be remade
  • 00:04:52
    into something
  • 00:04:53
    new try and reduce your impact you can
  • 00:04:56
    make a difference
