Life on Earth is wiped out every 27 million years – and we have about 16 million years left until the next extinction, according to scientists.
Research into so-called ‘extinction events’ for our planet over the past 500 million years - twice as long as any previous studies - has proved that they crop up with metronomic regularity.

The last extinction event, 11 million years ago, saw 10 per cent of the Earth’s inhabitants wiped out.
This means there is around 16million years until the next event takes place, although the graph shows that it occasionally the event takes place up to 10 million years
With surprising and mysterious regularity, life on Earth has flourished and vanished in cycles of mass extinction every 62 million years, say two UC Berkeley scientists who discovered the pattern after a painstaking computer study of fossil records going back for more than 500 million years.
Their findings are certain to generate a renewed burst of speculation among scientists who study the history and evolution of life. Each period of abundant life and each mass extinction has itself covered at least a few million years -- and the trend of biodiversity has been rising steadily ever since the last mass extinction, when dinosaurs and millions of other life forms went extinct about 65 million years ago.
Research has revealed that the rise and fall of species on Earth seems to be driven by the undulating motions of our solar system as it travels through the Milky Way. Some scientists believe that this cosmic force may offer the answer to some of the biggest questions in our Earth’s biological history—especially where evolution has fallen short.
Researchers at the University of California, Berkeley found that marine fossil records show that biodiversity increases and decreases based on a 62-million-year cycle. At least two of the Earth's great mass extinctions-the Permian extinction 250 million years ago and the Ordovician extinction about 450 million years ago-correspond with peaks of this cycle, which can't be explained by evolutionary theory.
Our own star moves toward and away from the Milky Way's center, and also up and down through the galactic plane. One complete up-and-down cycle takes 64 million years- suspiciously close to the Earth's biodiversity cycle.
Once the researchers independently confirmed the biodiversity cycle, they then proposed a novel mechanism whereby which the Sun's galactic travels is causing it.
Normally, our galaxy's magnetic field shields our solar system from this "galactic wind." But every 64 million years, the solar system's cyclical travels take it above the galactic plane.
"When we emerge out of the disk, we have less protection, so we become exposed to many more cosmic rays," Melott has said.
As the Earth’s solar system travels around the center of the Milky Way galaxy, it also wobbles up and down from the galaxy’s disc. U.S. scientists found that these swings take about 62 million years to complete—thus, may expose the Earth to higher doses of dangerous cosmic ray that may also cause mass extinctions.
With a 3-million year uncertainty in the calculations, that 64 million year cycle matches well enough with the 62 million year cycle of extinctions. The match resonates with Richard Muller, who says of the KU team: “They succeeded where I failed in coming up with a possible explanation for the effect that we observed.” And if they’re right, we have time to prepare for the next major event, since the Solar System has just passed the mid-plane of the galaxy.
The extinction event that cries out for explanation here is the most recent, the Cretaceous/Tertiary dinosaur extinction that dates back some 65 million years. It’s exceptional in this context because it occurred within two million years of the Solar System’s mid-plane galactic crossing.

Anywho, this makes sense.
Extinction is a major generator of life.
Just be happy that despite these extinction, life continues to evolve at the same rate:

With 2012 only a couple years away I hear a lot of talk about the biblical prophecies that most modern religions interpret as "the end of the world." This of course stems from several cosmologies from around the world that have astrological calendars with significant dates from 2011 to 2013. These philosophies include the Hopi Indians, Tibetan beliefs, and the famous Mayan calendar. I have noticed in the past, there has never been a shortage of interpretations regarding these exciting predictions. The challenge I found is the lack of unity these theories seemed to have. This is not a new trend. Throughout history when new philosophies are born it seems they rarely give much credit to their sources. You will notice most religious symbols, rituals, and holidays have pagan (A word Roman’s used for local or native) roots. Religion is the oldest game on the planet. On the other side Mysticism has over centuries adopted many of the structured beliefs we find mainly in modern religion. There is a teaching in the bible that states, by two or three witnesses will truth be established. I believe that by combining different philosophies we can find some clarity on these tricky prophecies. Read more: www.articlesbase.com... Under Creative Commons License: Attribution
Planet Earth is nearing the completion of an evolutionary cycle that originated approximately 480,000 years ago. At the beginning of each such cycle, a "blueprint" is established to guide the nature of the experiences that are to unfold throughout the cycle. With regard to Earth, the blueprint for this particular evolutionary cycle was designed to provide souls an opportunity to experience a great diversity of life forms. Thus, in the beginning, samples of genetic structures were gathered from planetary systems throughout our universe. These were then used to create a wide variety of plant and animal forms. Approximately 300,000 years ago, conditions had evolved to the point that it was deemed appropriate to seed the planet with sentient species. Thus, a large number of new souls were created, and a variety of human and cetacean forms were seeded upon the lands and within the oceans.
To battle against the world of darkness, you will need the world of light to triumph over the influence of war, you will depend upon the angel of peace; to battle against sickness, pagues, and death you will have the charity of those invisible beings who are ready to pour their balsam of charity and comfort upon humanity. Now that I have informed you of the kindness and elevation of these beings, I must tell you that they are pure and thus can speak to the world about purity. They love me and love you, therefore, they have the right to speak of love. They are saturated with health and well-being and can share this with those who are ill. Do you believe that they have always been virtuous beings? Are you not aware that a great number of them have dwelled on Earth and have known of the weaknesses and great faults?

In the case of mass extinction, we are outside this alleged 27 million year cycle and are perpetuating our own mass extinction event. It is called the Holocene Extinction
It has been well underway and irreversible as man slaughters countless species through industrialization, greed, pollution and oil spills.
The evidence clearly shows, the food chain is not surviving man's appetite. You are living in a Mass Extinction Event. Yet you probably do nothing to stop it.
