teacher Tracey here with Prezi Edie, you and we're going
- 00:04 - 00:05
to talk about methane.
- 00:06 - 00:10
Methane is a potent greenhouse gas and doesn't always get
- 00:10 - 00:12
the attention that carbon dioxide does.
- 00:13 - 00:16
Methane is in fact, 84 times more potent than carbon
- 00:17 - 00:20
dioxide in the short term, mainly because of how effectively
- 00:21 - 00:21
it absorbs heat.
- 00:22 - 00:26
Efforts to reduce methane emissions should be just as important
- 00:26 - 00:27
as reducing carbon dioxide.
- 00:29 - 00:31
What are the main methane culprits?
- 00:32 - 00:34
Let's play a game of true or false and get
- 00:34 - 00:38
a better idea and maybe dispel some methane myths and
- 00:38 - 00:39
prove some fart.
- 00:39 - 00:45
Fax. True or false cow farts contribute to the amount
- 00:45 - 00:49
of methane in the air, mostly false.
- 00:50 - 00:53
While cows do pass gas, it's the methane from their
- 00:53 - 00:55
Burkes that is far more harmful.
- 00:57 - 01:00
True or false, methane is produced through decomposition.
- 01:03 - 01:07
True, Think of what happens in wetlands, swamps and even
- 01:08 - 01:09
landfills. Plans.
- 01:10 - 01:13
Trash and other things begin to decompose and low oxygen
- 01:13 - 01:18
environments, and as bacteria breaks them down, methane is created.
- 01:19 - 01:23
If the surfaces of these environments are disturbed, methane is
- 01:23 - 01:24
leaked into the atmosphere.
- 01:25 - 01:29
This actually means that methane is released and rice Patties
- 01:29 - 01:30
as well.
- 01:32 - 01:35
True or false termites are a methane contributor.
- 01:38 - 01:43
True, as these would chomping bugs digest, bacteria breaks the
- 01:43 - 01:45
food down and out comes the guests.
- 01:46 - 01:50
It's estimated to equal 20 million tons of methane each
- 01:50 - 01:53
year. However, termites have a natural filter.
- 01:55 - 01:56
They're termite homes or mounds.
- 01:57 - 02:00
Help filter the methane before it enters the atmosphere.
- 02:02 - 02:05
True or false, mething can't be frozen.
- 02:07 - 02:11
False methane is frozen and trapped under Arctic ice.
- 02:12 - 02:16
And as the atmosphere warms and the ice melts, these
- 02:16 - 02:20
methane gas hydrates are released into the atmosphere and large,
- 02:22 - 02:23
concentrated amounts.
- 02:25 - 02:32
True or false, volcanoes are methane producers, true and false.
- 02:33 - 02:35
While methane may not come out of the mouth of
- 02:35 - 02:39
a volcano, the heat from a volcano acts is an
- 02:39 - 02:41
incubator for method and bacterial microbes.
- 02:42 - 02:46
And if we're talking about volcanic glaciers, but then the
- 02:46 - 02:48
heat is melting the ice and well, you get the
- 02:48 - 02:51
picture. True or false?
- 02:52 - 02:56
Methane leaks from the ground at oil, natural gas and
- 02:56 - 02:57
cold sites.
- 02:59 - 03:03
True and our energy production and drilling for oil, natural
- 03:04 - 03:07
gas and coal, the methane that has been built up
- 03:07 - 03:10
from millions of years leaks from the earth.
- 03:10 - 03:14
Methane is not easy to capture and transport so many
- 03:14 - 03:17
regulations have been put into place to limit the escaping
- 03:17 - 03:21
methane. This is yet another reason to seek energy alternatives.
- 03:23 - 03:26
Fred Krupp from the Environmental Defense Fund says that methane
- 03:27 - 03:31
pollution causes 1/4 of the global warming that we're experiencing
- 03:31 - 03:32
right now.
- 03:33 - 03:36
Scientists are studying ways to reduce the amount of methane
- 03:36 - 03:41
released into the air, which includes reducing plastic use, which
- 03:41 - 03:45
is another methane producer when heated by feeding cows probiotics
- 03:46 - 03:50
like seaweed and onions and launching a satellite that will
- 03:50 - 03:51
show methane leaks.
- 03:52 - 03:55
Hope you enjoyed these this insight into methane, and now
- 03:56 - 03:57
you know it's more than cow farts.
