pollution the presence or introduction into the environment of a substance that
0:04
has harmful or poisonous effects on the environment
0:07
and even us pollution comes in a variety of different way
0:11
news it may come in the water in the lower
0:17
or even in the air there are also two others
0:21
much less well-known light pollution and noise pollution
0:25
however those are not the worst of our problems
0:28
pollution can ruin our ozone layer it can prevent
0:31
plants from growing and even kill our animals let us start with a very
0:35
dangerous
0:36
but little-known former collusion now the dangers a plan
0:39
pollution plant pollution can be formed from many ways including industrial
0:43
activities
0:45
domestic waste an agricultural activities
0:48
land pollution is caused not just by landfill the domestic waste
0:52
but also by many other things including deforestation
0:55
which is the cutting down of trees industrial waste
0:58
such as nuclear substances mining and even some forms of mechanization
1:03
domestic waste including landfills can be a huge problem
1:07
domestic waste is the build-up home garbage in a certain place
1:11
they are a huge threat to the public landfills will attract debt your voice
1:15
and decomposers which are in some cases not good for the environment
1:19
the stuttered worries can include mice bowls seagulls
1:23
and other nasty beings despite all the problems posed by land pollution
1:27
that is not the least of our problems one serious problem posed by us would be
1:31
the introduction of water pollution
1:33
water pollution is not something that only comes from one source
1:37
it comes from many and those include waste watson's
1:40
sewage marine dumping and industrial pollution which includes oil pollution
1:45
waste waters are very dangerous both for your health and the health of your
1:49
eco-systems
1:50
so it would include all PCs urine and other toxic waste
1:54
if this waste is not read it below the bacteria will escape
1:58
causing the spread of diseases and in purification up water
2:02
leading animals to die when chemicals are in the water
2:05
they will cause immense damage to other nearby ecosystems
2:09
this type of water is referred to as brown sludge
2:13
on the other hand there is also a huge issue called coastal marine dumping
2:17
when substances are dumped into our water bodies it will be known as marine
2:21
dumping
2:22
no information about this was kept before the 1990s
2:25
any object could potentially be dumped into water these may include oil
2:29
plastics and other objects oil however is one that is very dangerous for the
2:34
help the bar
2:34
ecosystems Boyle takes a long time to be broken down naturally
2:38
and moves quickly throughout the Seas one prime example of this in action
2:42
would be the famous BP oil spill in the Gulf of Mexico
2:45
as shown here in case British Petroleum has sent 70 oil spillage
2:51
cleanup vessels in order to deal with any potential pollution
2:54
Katie slow
2:58
station I mean it raining
3:01
another table dumping is the dumping of chemicals
3:04
if there is too much alkaline in the water then animals can survive it that
3:08
pH level
3:09
indeed they will die one other huge method of water pollution would be the
3:14
dumping of plastics and other objects
3:16
these objects child and will kill over 100,000 marine animals each year
3:21
some beaches may even contain so many pollutants that can become an animal
3:25
graveyard
3:26
however aside from the beaches there is one place where this is definitely
3:29
present
3:31
in the pacific trash room taxes each one of the two is almost twice as big as
3:35
Texas
3:36
and is only growing larger these two garbage patches are connected by a
3:40
string of trash
3:41
called a six thousand mile long Convergence Zone there are more taxes in
3:45
every major sea or ocean
3:46
my
3:51
but did you also know that there is air pollution
3:55
air becomes polluted with noxious gases or black carbon particulates are
3:58
released into the air
4:00
there are three main gases that cause air pollution these are sulfur dioxide
4:04
carbon monoxide and nitrogen oxides
4:09
sulfur dioxide occurs mainly when palm oil are burned in power plants
4:14
this gas is also commonly found in smokestacks
4:17
as shown here
4:21
of
4:22
carbon monoxide is caused mainly by gasoline equipment
4:25
others are aircraft diesel and railroads carbon monoxide is much like carbon
4:30
dioxide
4:31
meaning that it is a harmful greenhouse gas nitrogen oxide only occur retire
4:35
temperatures
4:36
it facilitates and causes acid rain it is known to cause you to application
4:41
it is caused again by transportation vehicles
4:44
and power plant now to move on
4:47
a brief overview of black carbon pollution this phenomenon may account
4:52
for 18 percent of the world's global warming
4:54
it causes soupy brown hair this is only used to describe industrial particulate
4:59
pollution
4:59
did you know that nature creates its own pollution to
5:03
volcanoes spew ash into the atmosphere providing a stream of sulfur dioxide
5:08
the acid wracked with sunlight and blocks it sort of like what happened on
5:12
mount pinatubo
5:14
over towns and farmland killing more than 300 people
5:17
windstorms can also pick up to it and place it in the atmosphere
5:22
forest fires can create industrial sized smog
5:25
and can release carbon from the trees into the atmosphere
5:28
organic matter dies and when they do they will release their carbon into the
5:32
atmosphere
5:33
also when warmed our oceans will release some of the common they have stored
5:38
causing natural pollution
5:39
please note but this was all under regulation before the arrival of humans
5:44
if not for us pollution would not be a problem
5:47
pollution also had negative affect on our ecosystems
5:50
amphibians are hit hardest by water pollution they absorb water do their
5:54
skin
5:55
so any toxins present get directly inside their bodies
5:58
by insects will no longer be able to glide on water
6:02
due to the amount of pollution in the former debris or oils
6:06
in a land ecosystem when chemicals seep into the ground
6:09
plants may be tainted and will not be able to perform core functions
6:13
it's about time that you face the facts we must do something about pollution
6:17
pollution is bad for our health it kills millions of people each year who get
6:22
heart disease
6:23
lead poisoning and even some lung problems
6:26
and furthermore forty percent of America's rivers are too polluted from
6:30
fishing
6:31
swimming or aquatic life what can we do to help this growing problem
6:35
we can recycle plant a tree get better fuel efficient cars
6:40
or even contact their local authorities in governments to raise awareness
6:44
and put in place plans to make our community a cleaner
6:48
ecological place New Year just passed over
6:51
the development in northern Alberta
6:54
about the tar sands pollution affects us through the air
6:59
the land and the walls this is something we must be aware of as we proceed into a
7:04
hopefully greener future
7:05
to this a good day it's a good day fight
