Scientist 1 suggests that:
F. Humans will always be adapt to any changes in Earth’s atmosphere and environment.
G. The earth will no longer be able to sustain human life in 7 billion years.
H. Sufficient time and incentive are not necessary elements in advancing technology.
J. Creating sunshades would help to increase levels of carbon dioxide in the air, which is important in maintaining life on the planet.

Scientist 1
Earth’s sun has another 7 billion years before it enters the Red Giant phase. Currently, Earth could not sustain human life during the Red Giant phase. However, it is important not to believe that human life on Earth will immediately cease to exist as we know it in 7 billion years. Technology has played a huge role in helping humans adapt to conditions on this planet. We humans have 7 billion years to advance technology and find solutions to adapt to the atmospheric changes the Red Giant phase would bring. For instance, creating a large sunshade to protect Earth would allow life to continue even when the sun enters the Red Giant phase. Another solution would be to develop technology that would stir the sun and bring new hydrogen to the sun’s core. This would greatly extend the current phase that our sun is in. There is enough time and incentive to discover ways to thwart the natural progress of nature. Therefore, I believe that human life on this planet will exist indefinitely.
