During my recent debate with Justin Vacula, he brought up the problem of so-called 'natural evil', asking why natural disasters occur. Insofar as the example of earthquakes occurring that Justin brought up, I linked
an article quoting the director of the German Space Research Centre Institute of Planetary Research and chairman of European Space Agency’s scientific advisory committee, Tilman Spohn. Spohn notes ...
"It is an idea growing in popularity among planetary scientists. Says Spohn, “plate tectonics replenishes the nutrition that primitive life could live on. Imagine a top surface that is depleted of the nutrition needed for bacterial life. It needs to be replenished, and plate tectonics is a method of achieving this.”
Spohn found that the further he delved into the issue, the more important plate tectonics seemed to be for life. For example, it is believed that life developed by moving from the ocean to the kind of strong and stable rock formations that are the result of tectonic action. Plate tectonics is also involved in the generation of a magnetic field by convection of Earth’s partially molten core. This magnetic field protects life on Earth by deflecting the solar wind. Not only would an unimpeded solar wind erode our planet’s atmosphere, but it also carries highly energetic particles that could damage DNA.
Another factor is the recycling of carbon, which is needed to stabilize the temperature here on Earth. Spohn explains, “plate tectonics is known to recycle carbon that is washed out of the atmosphere and digested by bacteria in the soil into the interior of the planet from where it can be outcast through volcanic activity. Now, if you have a planet without plate tectonics, you may have parts of this cycle, but it is broken because you do not have the recycling link.”
It has also been speculated that the lack of tectonic action on Venus contributed to its runaway greenhouse effect, which resulted in the immense temperatures it has today."
I personally thought using so-called 'natural evil' as an argument against the existance of God to be absurd, and on a couple of different levels. Last night while surfing the net, I came across this article by Dinesh D'Souza (above) which deals with another objection that skeptics might raise. D'Souza quotes "Rare Earth, a 2003 book by Peter Ward and Donald Brownlee that traces the myriad conditions required for life to exist on any planet. In a sense, the authors—an eminent paleontologist and an astronomer at the University of Washington in Seattle—are discussing the "anthropic principle," which specifies the degree to which our planet appears fine-tuned for complex life." D'Souza goes on to note...
"Why didn't God devise a world that didn't require plate tectonics and consequently one that wouldn't have to put up with earthquakes?" In other words, surely God could have made a universe that operated according to a different set of laws.
Ward and Brownlee's answer to this is as simple as it is devastating. Such a world could have produced life, but it surely could not have produced creatures like us. Science tells us that our world has all the necessary conditions for species like Homo sapiens to survive and endure.
Our planet requires oxygen and a warming sun and water in order for us to live here, and we appreciate this, even though we recognize that people can get sunstroke and drown in the ocean. So, too, it seems that plate tectonics are, as Ward and Brownlee put it, a "central requirement for life" as we know it.
This is not to suggest, as the scientist and philosopher Leibniz once argued, that ours is the best of all possible worlds. But ours may be the best of all feasible worlds, at least as viewed from a human perspective."
So there you have it, earthquakes are necessary for life. It also appears that hurricanes serve a purpose too. Gravity occurs through natural processes and bad things can concievably come about because gravity exists, but nobody is going around arguing that the planet would be better off without gravity.
The important thing to keep in mind, as philosopher Peter Kreeft once mentioned, is to be there for people when bad things occur in their lives. To be Christ for them as God's love shines through us as we comfort them in their time of need and despair.
