All animals and plants will vanish from the Earth within the next billion years, a new study suggests.

The predictions are based on a computer simulation of the impact long-term changes to the Sun are likely to have on Earth.

Ironically, the end of the world will arrive as a result of too little carbon dioxide in the atmosphere, rather than too much.  At the moment, experts are seeking ways to cut levels of the greenhouse gas to prevent global warming running out of control.

However, scientists predict a future with the aging Sun growing hotter, leading to greater evaporation and chemical reactions. Rainwater will remove more and more carbon dioxide. In less than a billion years, levels will be too low for photosynthesizing plants to survive.

As the Sun ages over the next billion years or so, it is expected to remain stable but to grow steadily brighter. The increasingly intense radiation will cause the Earth to heat up to such an extent that the oceans start to evaporate.

When that happens, life as we know it on Earth will cease to exist.

These speculations are interesting as long as they don't affect us here and now. Our forebears struggled to survive, lorded it over the animals, and even shot precious tigers as trophies all without a thought of what would happen in the future. We're doing the best we can for the planet now, based on what we know.

Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in varied forms.  The earliest evidence for life on Earth comes from fossilized mats of cyanobacteria called stromatolites in Australia that are about 3.4 billion years old. Ancient as their origins are, these bacteria (which are still around today) are already biologically complex—they have cell walls protecting their protein-producing DNA, so scientists think life must have begun much earlier, perhaps as early as 3.8 billion years ago.

But despite knowing approximately when life first appeared on Earth, scientists are still far from answering how it appeared. Today, there are several competing theories for how life arose here. Some question whether life began on Earth at all, asserting instead that it came from a distant world or the heart of a fallen comet or asteroid. Some even say life might have arisen here more than once.

I prefer to believe in a loving God, waiting in heaven for me to arrive home again. I think I've been here many times before and learned during each lifetime.
We all have an idea about life.
My husband thinks when we die, that's the end of us. Like a tree.
My daughter thinks aliens or divine beings are waiting to transform us right now.
However, nobody really knows.

Gosh, I'm impressed that you write every day and manage such in depth well researched posts. Very topical too.

Thank you. I just look over the headlines and find something that sparks my interest. Then, I research some background.

I am on the loving God side of thing. Through Jesus I will enter eternity.

I agree with Phoebe! It must be tricky coming up with a completely different topic everyday. I myself find it easier to write fiction :)
It's a scary thought that one day the Earth will cease to exist, I hope it's thousands of years after we're gone!

I don't think we need to worry about ourselves--just those who follow.

Francene,
Gosh, you must never stop thinking, my friend! You must even come up with fantastic blog posts in your sleep. I am on the "loving God" side of this issue, too. Sometimes I wish I could just see the future and see what's going to happen to this old earth and everything on it, but the Bible says that nobody--not even the angels--know the time when Christ will return. So I guess God doesn't want us to know, but I can relax knowing that He is waiting for me and that there will be no tears and no suffering where He is.

This removes any need to worry. Let's live life as best we can, bearing in mind those who follow.

It's amazing to think that not only can we know such things from the distant past but that we can also predict those from the distant future as well.
I'm not religious, I have no idea what will happen when I die and I'm okay with that.

I sometimes think mankind is too clever for their own good. As long as they use their minds for good purpose, I'm all for it.

I'm with you on God creating the earth. It's what I've grown up knowing and although I used to be overwhelmed with the "how" it doesn't bother me anymore. I just "believe".

Faith removes all doubts. How can we know the unfathonable? Thanks for commenting, Madison.
