Water is an essential constituent of healthy, productive soils. It serves to bind and secure the physical particulates in soil structure and is the medium by which natural chemicals and essential trace element nutrients are transported to plants.
If Antarctica has coal beds, and coal is formed from pressured carbon, then it indicates that Antarctica once had living organisms. Because living things are carbon based.
Climate change is the charge of earth temperature from cold to warm to hot this, change is brought about by both man and nature induced factors in the environment.
Climate change is a universal phenomenon, it impacts every part of the earth and is not the same everywhere as someplace has a huge climatic impact while others have minimal, and others are badly impacted this further depends upon the alternation to the climate by man.
Changes in precipitation, rise in temperatures both on land and water and depletion of resources are fundamental to the large scale impact of climate change and this reduces the survival rates to various species to the planet, the loss of dinosaurs was in itself a big impact of climate change that to place millions of years ago and from that period onward the earth is getting heated and continues to get hot a hotter day by day.
Polar areas and ice caps are badly impacted reduction of land surface and increase in oceanic waters becoming more saline and changes in the atmospheric carbon content and depletion of stratospheric ozone are warning signs based on global climatic pattern's and data collected by decades of surveys around the world.
Shortly, this climatic induced forces will further lead to more drastic flooding and rains which if unchecked will bring another age of global cooling.
If you are asking which continent has the largest population then it would be Asia with 4.46 Billion people accounting for more then 62% of earths human population
