Our planet has been explored on land, sea, atmosphere and the reaches of Space beyond. All the information earned over the last century has presented us with a complexity that did not exist to this previously previously. We are facing the fact that our explorations and activities have harmedally affected the soil and its vegetation, our waterways, seas and our atmosphere that all suffer as a result. Pristine conditions can not now exist in the state of the natural elements we are familiar with, and even those we have yet to see or discover in the micro spheres.
It would seem that we are proud to have discovered many laws and processes in our natural world but as yet can offer no correction that is satisfactory in curbing the negative effects of our human activity. There is little time to make any correction as it looks Nature itself is in the process of eliminating what we have come to accept as the normal environmental conditions we have enjoyed on our planet. These natural happenings we all know are intensifying. The extreme weather conditions and changes, the floods, tornadoes, earthquakes and volcanic activities all over the planet have increased in number and varying intensities that cause concern to our scientists and naturalists.
It is the last mentioned, that is volcanic activity, that has been of concern confined to those who live in near environments to the active volcanoes but should be of concern to us all. The reason is that we know very little about what is the true nature of the deep interior of our planet and if we are to avoid disturbing the hot magma beneth the thin surface crust we must take further care.
The inner environment of the earth is only comparatively recently explored. We know that the outer crust of our earth is a thin and brittle nature. Then deeper is the mantle and down further, the central core. It is the mantle that occupations the greatest volume and contracts a great deal of concern for that reason. At present the knowledge about its constituents is limited but from the movement of the tectonic plates that have a long history of movement and change, scientists conclude that the mantle material then increases in density down to denser substances. The hot mantle zone is at varying depths from the surface crust and produces the molten magma that rises to the through the outlets of existing volcanoes when an eruption occurs.
Geologists have intensified their studies directly associated with the interior of the core since the more recent cases of earthquakes and volcanic activity through the globe. It seems that one factor of the assessment of the temperature of the innermost core is equivalent to the 6000 degrees on the Sun surface! For most of us, this means very, very, very hot!
As laymen we could have forgiven for wondering how deep drill mining is affecting what is deep down in our planet, as well the underground explosions and nuclear tests we have heard about.
Hopefully scientists can one day insure us that there is no danger of the hot magma increasing to destroy human surface activity. But it is not hopeful, as there are many signs of old volcanoes awakening from dormancy, even the giants such as Krakatau!
Nature will have its way and maybe humans will with urgency change our ways to demonstrate respect for the environment we say we cherish but have seriously harmed.
