I seen a lot of things like global warming, over population and even the sun going to a red giant phase and scorching the earth - what do you think will most likely happen? I personally kinda always felt like mankind is its worst enemy and I heard lotta people say that as soon as even our grand children the earth may no longer be able to sustain life for humans because of pollution and damage to the ozone. A part of me kinda wants the earth to be destroyed cus some really fucked up things have happened on this place and I think it would be most beautiful for all life to cease and just have this giant ball of history just continuing its orbit around the sun indefinitely.
also they say every star in the sky represents a solar system just like ours, do you think there is life on other planets out there somewhere? I kinda feel like odds are there is, at the very least I would bet that single celled organisms exist somewhere out there.
The sun will burn up life on earth long before it goes red giant and engulf the earth.
The sun has been steadily brightening since 4.5 billion years ago. It will get much brighter still before it runs out hydrogen to fuse in its core and enter the helium burning phase to become a red giant.
Earth and its biosphere has coped with the gradual increase in solar brightness and heat out out by gradually reducing the greenhouse gases in the atmosphere. We may think we are putting a lot of greenhouse gases back into the atmosphere, but the total amount pales compare to what they were in the geological past. The truth is there is no a whole lot more greenhouse gas left in the atmosphere that can be removed to compensate for increasing solar output. As the sun heats up and brightens more, biosphere and geosphere will run out of more greenhouse gases to pull out the atmosphere to compensate. When that happens, a slow, inexorable, irreversible natural global warming will occur. Eventually That will trigger a vicious feed back cycle that will cause the oceans and the earth to regurgitate back into the atmosphere orders of magnitude more greenhouse gas than the atmosphere had ever contained before, leading to a runaway greenhouse effect, that will destroy all life on earth.
Estimates give life on earth another 500 million or so years. After that it's over. Life on earth has already ran 85% of its expected life expectancy.
