The Earth has been around for about 5 billion years, and has about another 5 billion years to go.  It has been cooling since its formation, and its surface temperature has stabilized within about 100 degrees F of the freezing point of water.  This is critical, as liquid water appears to be a prerequisite condition for life.

As the Earth cooled, what we would consider a poisonous atmosphere evolved, containing high concentrations of methane and some ammonia. "Hard" ultraviolet radiation provided energy to get molecules to react in the early oceans, and biochemical processes began.  Oxygen, then a poisonous byproduct, began to accumulate in the atmosphere; aerobic life flourished.  As climate conditions altered, life forms altered as well, and will continue to do so.  Atmospheric changes 65 million years ago killed off the dinosaurs; several "Great Dyings" have been found throughout the Earth's history in the geologic record. Human population continues to increase, but will begin to slow and decline.  Increasing carbon dioxide production by human activity has exacerbated what may be a naturally occurring climactic warming trend. The increase in carbon dioxide in the atmosphere is now considered a poisonous byproduct.  Although humans may live or survive upon the Earth, or may not, the Earth will continue to exist  with some kinds of life.  However, all life will cease on the planet when the Sun goes nova in several billion years.

Earth's present condition is that it is in a damged state and under threat from dangers including those arising from global warming.

These threats include greenhouse gases,droughts and floods,hunger and famine and devastating diseases such as malaria and aids.

Some experts scientists are calling for carbon taxes to cut the risk. Damage from flooding alone could run into billions of dollars as creeks and estuaries beging to fill up and more ice melts. Climate change is seen by some scientists to present the biggest threat to our world today. The whole world needs to effect remedial   strategies by co-operating.

Levels of gases such as carbon dioxide are rising still and we are still at risk from deforestation and the burning of fossil fuels. Greenhouse gases may cause the world to warm up as heat cannot escape effectively from the surface of the planet. All of this might throw the natural rhythms of our world's climate. That's where we're at right now!

There is a lot of things that can be stated. Like the first post stated the earth seems like it is in a damaged state. We could sort of tell by the number of advocates for the earth. Global warming seems to be on the rise and if it continues, it can exacerbate the damage of the earth.

Apart from this concern, there is the work of big companies, like oil companies that seek to drill and extract as much oil as possible. For profit, people are also cutting down rain forests at a rapid pace, which are necessary for the earth's health. These are two examples, but there are many more ways in which we are harming the earth.
