1. 0:07I died several times
2. 0:10and now you might be wondering what does
3. 0:13a 14 year old girl know about dying well
4. 0:16let me tell you I died when I inhale the
5. 0:19chlorofluorocarbons from the AC
6. 0:22I died when I ate the highly dangerous
7. 0:25food with added chemicals and
8. 0:27preservatives
9. 0:29I died when I drank water from our
10. 0:31Rivers
11. 0:33are we also not dying when all of this
12. 0:35is happening around us
13. 0:37ladies and gentlemen my name is Keith
14. 0:39kigosavi and I am here to talk about
15. 0:41climate change
16. 0:43now what exactly is climate change
17. 0:46by definition climate change is a
18. 0:49gradual heating of our planet through
19. 0:51the emissions of greenhouse gases ghg it
20. 0:55is an effect of human activities on our
21. 0:58planet more specifically industrial
22. 1:00activities
23. 1:03now what are the effects of climate
24. 1:05change
25. 1:07increasing temperatures the global
26. 1:09surface temperature rises together with
27. 1:12greenhouse gas concentrations
28. 1:14the hottest decade recorded was from
29. 1:172011 to 2020 that is more recent
30. 1:21there are more hot days and heat waves
31. 1:23now than there were ever
32. 1:27the Arctic is melting twice as quickly
33. 1:30as other locations that leads us to
34. 1:34severe storms in many areas destructive
35. 1:38storms have increased in ferocity and
36. 1:41frequency
37. 1:42as the temperature increases more
38. 1:44moisture evaporates resulting in very
39. 1:47heavy rainfall and flooding
40. 1:50that then result in more severe storms
41. 1:53that give us sorry that demolished
42. 1:56houses and towns
43. 1:59moving forward to heightened dropped
44. 2:02water supply is changing due to climate
45. 2:04change it is becoming more and more
46. 2:06limited in many places in already what a
47. 2:10stress areas climate change is making
48. 2:12things worse
49. 2:13it increases the danger of ecological
50. 2:16and agricultural trots which can be
51. 2:19harmful to our crops and make our
52. 2:22ecosystem more vulnerable
53. 2:24it Sparks the sandstorms that carry
54. 2:27billions of tons of sand across
55. 2:29continents
56. 2:31that leads us to insufficient food
57. 2:34now how you may ask well the more the
58. 2:38desert the less the agriculture Global
59. 2:41hunger and poor nutrition are on the
60. 2:43rise for a variety of reasons including
61. 2:46climate change crops animals and
62. 2:49Fisheries might all be lost
63. 2:51Marine Resources that provide food for
64. 2:54billions of people are in danger
65. 2:57food sources from hunting and fishing
66. 2:59have been hampered in several Arctic
67. 3:02locations due to snow and ice cover
68. 3:04changes
69. 3:06moving forward we get to more health
70. 3:08risks
71. 3:10there is only one thing that is now very
72. 3:13dangerous to humanity
73. 3:14and that is climate change air pollution
74. 3:18sickness harsh weather Force relocation
75. 3:21stress on mental health and increasing
76. 3:23hunger in areas where people cannot even
77. 3:27grow food are some of the examples 13
78. 3:31million individuals every year are
79. 3:34killed by environmental conditions
80. 3:36extreme weather events increase
81. 3:38fatalities making it challenging for
82. 3:41Health Care Systems to keep up with the
83. 3:43growing number of the diseased and
84. 3:45taking care of them
85. 3:47that leads us to declining species
86. 3:50the rate of Extinction on the planet is
87. 3:531000 times higher now than it has ever
88. 3:55been
89. 3:57threats from climate change include
90. 3:59exotic pests and illnesses forest fires
91. 4:02and harsh weather
92. 4:04a very good example of forest fires
93. 4:06would be the Amazon forest fire
94. 4:09one million species will be extinct in
95. 4:13several decades ahead
96. 4:15moving to rising sea levels all ocean
97. 4:19depths have experienced a significant
98. 4:22rise in Ocean warming during the past 20
99. 4:25years
100. 4:26sea levels increase as a result of
101. 4:28melting ice sheets endangering Coastal
102. 4:31and island people
103. 4:33additional CO2 is absorbed by water
104. 4:35keeping it out of the atmosphere but
105. 4:39it causes the ocean to become more
106. 4:41acidic endangering coral reefs and
107. 4:45marine life
108. 4:46now let us take a look at the causes of
109. 4:49climate change
110. 4:51endless desire of humans to produce
111. 4:54power is one of the reasons
112. 4:56burning coal oil or gas still supplies
113. 5:00the majority of the world's electricity
114. 5:02which produces carbon dioxide and
115. 5:05nitrogen oxide to potent greenhouse
116. 5:08gases that covers the planet
117. 5:10and trap the sun's Heat only a little
118. 5:14over the quarter is contributed through
119. 5:16renewable energy resources
120. 5:19moving on to deforestation a very big
121. 5:22problem currently destruction of trees
122. 5:25reduces Nature's capacity of emissions
123. 5:28out of the atmosphere because they
124. 5:31absorb carbon dioxide
125. 5:34cutting down forests to make way for
126. 5:36Farms pastures or even other purposes
127. 5:40increases emission because when trees
128. 5:43are filled they stored carbon inside the
129. 5:45trees is released leading to increasing
130. 5:48temperatures thus leading us to global
131. 5:51warming
132. 5:52moving forward consuming excessively
133. 5:56you can reduce greenhouse gas emissions
134. 5:58by changing the way you live how much
135. 6:00you throw away how much you eat and how
136. 6:02much you move around
137. 6:05private property owners
138. 6:07give or contribute a whole percent
139. 6:10to the greenhouse gas emissions the
140. 6:12richest one percent of worse population
141. 6:16together contribute to greenhouse gas
142. 6:18more than the lowest 50 percent hence
143. 6:22they suffer the most burden
144. 6:24now do you think it was right of us to
145. 6:27use all of this
146. 6:28do you think Humanity Will Survive
147. 6:31further
148. 6:32let me give you an interesting fact
149. 6:34nature keeps adapting it is US humans
150. 6:37that take more time
151. 6:39so now is our time to stand up on our
152. 6:42feet
153. 6:43and start working thank you ladies and
154. 6:46gentlemen
155. 6:47[Applause]
