Our Solar System

Our Solar System Earth is the third planet from the Sun and the only astronomical object
known to harbor life. It is the densest planet in the Solar System and
the largest and most massive of the four rocky planets. About 29% of
Earth's surface is land, with the remaining 71% covered with water and
much of Earth's polar regions covered in ice. Earth's interior is active
with a solid iron inner core, a liquid outer core that generates Earth's
magnetic field, and a convective mantle that drives plate tectonics.
Earth formed over 4.5 billion years ago. Within the first billion years
of Earth's history, life appeared in the oceans and began to affect
Earth's atmosphere and surface. Since then, the combination of Earth's
distance from the Sun, physical properties and geological history have
allowed life to evolve and thrive. Almost 8 billion humans live on
Earth and depend on its biosphere and natural resources for their
survival, but increasingly impact Earth's surface, atmosphere and other
life. (This article is part of a featured topic: Solar System.).

What is interesting as I read about our Solar system is that we have over 8 billion people on this earth and with so many people on the earth we will eventually use up our resources for survival.

This is earth day with concerns of trouble with atmosphere and weather climate changing on the earth. I have not done a complete research on this subject, but I would like to know how serious is the climate?  

I hope our earth will be okay where all nations put on their thinking cap with healing our earth.

Happy Earth day!!!!
