1: What would happen to our planet if the human population suddenly disappeared? | http://www.youtube.com/watch?v=K5wP6m0d0xc
2: Population Progression | Soon after all life disappears from earth the decomposition of human remains will begin to take place. Like fertilizer our remains will help the growth of grasses and plants around the world. As the years progress all the buildings and skyscrapers will begin to rot and rust away. Only the bits and pieces of the buildings' skeleton sare guessed to remain. After decades the world will begin to reaccustom itself to a time before the human race invaded. Only small signs of the damage that was done by an overpopulated race will leave any sign of any period of human life.
3: Effect on Resources | Most resources consist of food, water, shelter, and oxygen. Each category of resources consists for both animal and man. Food: Processed food will soon become an extinct subject, and only natural food, like plants and prey, will be available for animals. Water: There will always be types of lakes, rivers, and oceans on the earth to supply water for the non-human species. Rain will continue to nourish the plants and animals. Shelter: Animals will continue to find instinctual places to live and keep safe. Oxygen: Nothing can survive without it.
4: Effect on Non-Human Species | House pet animals, like dogs, would be the first the things to die. Without the help, support, and resources of humans many of these animals would not survive past the first year of a nonhuman population. Rats, mice, and other house pests would also have a massive die off. After finishing off what was left of “human food”, these animals would have to survive off of cardboard and glue. Predator/prey relationships would soon take on a whole new meaning, and the hunts would literally take place in our own backyard. The fight for survival is raised because there are no humans keeping this relationship at bay. Many carrying capacities will reach their limit, while others drop almost to the point of extinction.
5: Effect on Climate | The climate of the earth after the human population has left can be estimated to drop to a lower temperature, and cause an increase in rain. Yet many of earth's areas will see some of the same levels of climate; many will change due to the multiple amounts of plants popping up and a decrease in the burning of Fossil Fuels.
6: Effect On Biomes | Many biomes will remain as they were during the period humans on earth. Others though will see a drastic change in their environment. It is assumed that many of the river and lake areas will dry up. Leaving little remaining from the days of water flowing. While many rivers and lakes dry up some will overflow with water. These areas will reach their carrying capacity and overflow the land. The overflow will create a marsh area. Many of the biomes including the desert, forests, and grasslands will see similar effects. Due to the increase of rain, and the decaying animals' bodies creating new soil, many trees and plants will take over the land.
