Hello all
00:02 - 00:09
the topic for my weapons project was are we too far gone for a healthy blue planet
00:09 - 00:14
or can we reach potential resolution of these threads
00:14 - 00:16
before a climate tipping point.
00:17 - 00:21
Technological advancements has made our lives comfortable
00:21 - 00:23
while damaging our
00:23 - 00:24
atmosphere.
00:25 - 00:29
We have made travel faster manufacturing time, efficient
00:29 - 00:35
difference between day and night is gone with the provision of 24 7 electricity.
00:36 - 00:38
In short we are able to craft such a
00:38 - 00:40
convenient life for ourselves
00:41 - 00:43
but at what cost
00:44 - 00:45
in the end
00:45 - 00:47
it is destroying our environment.
00:47 - 00:53
But can we revert to old times or are we ready to spend that much time on completing
00:54 - 00:56
minor everyday tasks?
00:58 - 01:03
There is no question industrialization have proved detrimental
01:03 - 01:05
to our ozone layer,
01:08 - 01:10
transforming economies.
01:10 - 01:14
Health professionals and health journals have been born in for decades
01:14 - 01:18
about the severe and growing effects from climate change
01:18 - 01:23
including extreme temperatures, destructive weather events
01:23 - 01:26
and the degradation of essential ecosystem.
01:27 - 01:28
The IPCC
01:28 - 01:34
report shows that every fraction of a degree harder and dangers are health and
01:34 - 01:35
future.
01:37 - 01:40
So there is the need for rapid and profound change
01:41 - 01:44
and it's this need is based on the scientific
01:44 - 01:47
findings and the political commitments to the paris agreement.
01:48 - 01:50
The activists are therefore factually right.
01:50 - 01:51
However,
01:51 - 01:57
being right is not enough to justify or to accelerate the practical implementation
01:57 - 01:59
of knowledge and decision.
02:01 - 02:04
We need to do something to save our planet.
02:05 - 02:07
With the help of knowledge of science and
02:07 - 02:10
technology we can detect and prove global warming
02:11 - 02:13
and with the use of scientific knowledge,
02:13 - 02:16
scientists are trying to find different solutions
02:16 - 02:22
to save climate from harmful effects of various phenomenon happening around us.
02:22 - 02:27
So in today's circumstances, technology and the knowledge of stem
02:27 - 02:34
seems to be our only hope to fight climate change and we can reverse it.
02:34 - 02:36
With the use of various technological
02:37 - 02:40
innovations, such as the use of
02:40 - 02:43
reversible renewable energy sources,
02:43 - 02:49
as well as use of different technologies where we can help our ozone layer
02:49 - 02:50
to revive.
02:50 - 02:55
If all human emissions of heat trapping gasses were to stop today,
02:55 - 02:59
arts temperature would continue to rise for a few decades as ocean currents
03:00 - 03:04
bring excess heat stored in the deep ocean back to the surface.
03:04 - 03:09
Once this excess heat radiated out to surface earth's temperature would stabilize
03:10 - 03:13
experts saying the additional bombing from this hidden
03:13 - 03:17
heat are unlikely to exceed 0.9 degree Fahrenheit
03:17 - 03:21
with no further human influence. Natural policies would begin to slowly
03:22 - 03:25
remove the excess carbon dioxide from the atmosphere
03:26 - 03:28
And global temperatures would gradually
03:28 - 03:29
begin to decline.
03:30 - 03:33
Renewable energy is energy derived from natural
03:33 - 03:36
process that are replenished at a rate
03:36 - 03:38
faster than they are consumed.
03:38 - 03:43
Global renewable energy installations hit record high in the year 2020,
03:43 - 03:44
making experts predict
03:44 - 03:48
that renewable energy sources will replace coal
03:49 - 03:49
in
03:49 - 03:51
2025.
03:51 - 03:54
There are different types of renewable energy sources.
03:54 - 03:59
When solar, ocean hydropower geothermal biomass,
04:01 - 04:05
wind energy is the kinetic energy in wind can be converted to useful
04:06 - 04:06
forms.
04:07 - 04:12
Ocean energy, which is the energy in the waves and tides can be converted into
04:12 - 04:13
electricity.
04:14 - 04:18
Then there is the hydropower, which is energy brain from moving waters of ocean
04:18 - 04:19
geothermal,
04:19 - 04:23
which is the energy obtained from the energy
04:24 - 04:28
strapped under the surface of earth and atmosphere.
04:28 - 04:33
And then there is a biomass biomass is a biological material stored in solid liquid
04:33 - 04:40
and gas is form that has stores and light in the form of chemical energy.
04:40 - 04:44
Out of all these most important is the solar.
04:44 - 04:48
So today to active solar technologies that involve
04:48 - 04:52
electrical or mechanical equipment are becoming more common.
04:52 - 04:57
First solar collectors or panels are used to heat water or ventilation air
04:58 - 04:59
for use in buildings
04:59 - 05:05
and second solar photovoltaic technology uses solar cells to convert sunlight
05:05 - 05:07
directly into electricity.
05:08 - 05:13
There are numerous advantages associated with renewable energy sources,
05:13 - 05:18
renewable energy will not finish lower maintenance requirements, save money,
05:18 - 05:19
numerous
05:19 - 05:20
environmental benefits,
05:21 - 05:24
lowers reliance on foreign energy sources,
05:24 - 05:27
leaves to clean water and air
05:27 - 05:29
And can cut down on waste.
05:29 - 05:35
While there are some disadvantages associated with renewables as well,
05:35 - 05:36
which are high cost,
05:36 - 05:37
intermittent
05:37 - 05:39
limited storage capacity,
05:39 - 05:45
have geographical limitations and are always 100% carbon free.
05:46 - 05:49
While these renewables and these technological
05:50 - 05:55
advancements present a promising future for our environment,
05:55 - 05:57
there's still a lot of need,
05:57 - 06:00
a lot of needs for work to be done in this
06:00 - 06:08
field and without complete dedication to achieve our goal for,
06:08 - 06:11
to reverse carbon environmental.
06:12 - 06:16
Um Kara global warming. We cannot achieve this.
06:16 - 06:20
Uh without the continued dedicated effort,
06:21 - 06:24
Greta Thunberg is the Swedish environmental activist and
06:24 - 06:28
known for challenging world leaders to take immediate actions
06:28 - 06:31
to improve environment. Her activism began at home
06:31 - 06:36
when she persuaded her parents to take actions to reduce their carbon footprints
06:36 - 06:38
to decrease her own carbon footprint.
06:38 - 06:41
She sailed in a Yash to attend a conference in 2019
06:41 - 06:44
Climate action summit in North America.
06:44 - 06:45
Her speech there,
06:45 - 06:50
How dare you made her famous her message before she embarked on a journey for C.
06:50 - 06:55
O. P. 25 conference was the same as it has been since she began her activism.
06:56 - 06:58
My message to the americans is the same as to everyone
06:59 - 07:02
that is to unite behind the science and to act on the science
07:04 - 07:07
asserts that humanity is facing an existential crisis
07:08 - 07:12
because of global warming and holds the current generation of adults responsible
07:12 - 07:17
for creating the problem. She uses graphic analogies such as Our House is on fire
07:17 - 07:20
to highlight her concerns and often speaks bluntly
07:21 - 07:24
to business and political leaders about their failure to take
07:24 - 07:26
concerted actions.
07:41 - 07:45
Greta Thunberg was diagnosed with Asperger's syndrome at 11 years of
07:45 - 07:50
age and she was depressed about inaction regarding climate change.
07:50 - 07:57
She, the campaign she started was Fridays for future and she started,
07:57 - 08:00
she and her school aged friends,
08:00 - 08:03
they all started campaigning outside the Parliament house
08:03 - 08:08
to increase awareness about the climate survival.
08:08 - 08:12
While she has support from almost all the world leaders,
08:12 - 08:16
some of the world leaders like former US President Donald Trump.
08:16 - 08:21
They marked her enthusiasm about saving the environment
08:21 - 08:25
and he even suggested that she should go for anger management.
08:25 - 08:27
But apart from him,
08:27 - 08:28
most the world leaders expressed support for
08:28 - 08:31
her campaign and she has been nominated
08:31 - 08:34
for Nobel Peace Prize in 2019,
08:35 - 08:36
and 2021.
08:38 - 08:42
She is known for her blunt youthful style of
08:42 - 08:48
speaking and the concern she shows for the environment saving
08:48 - 08:51
while agreeing with most of the points,
08:51 - 08:57
it's impossible for us to stop using technology altogether.
08:57 - 09:00
So um as a whole,
09:00 - 09:05
I will conclude that trying to aggressively employ
09:05 - 09:08
these environment saving strategies in our everyday life,
09:08 - 09:14
use green um options everywhere where they're needed,
09:14 - 09:16
like using solar cells for electricity
09:17 - 09:23
And other renewables to have our daily day to day work
09:23 - 09:29
accomplished is the best way to stop these carbon emissions.
09:29 - 09:35
And in the end while it's not going to be done overnight, but after a while,
09:35 - 09:40
maybe a year, like a time period of 10 or 20 years, we will be able to reverse
09:41 - 09:44
these global warming and save our planet.
