SimEarth: The Living Planet/Edit menu

The edit menu contains a wide variety of objects which can be placed in your planet, and actions that can be performed in an area on your planet.

Biomes

 * Rock (50&#937;): Bare rock; the absence of biome. Life cannot survive here.
 * Arctic (50&#937;): Glaciers and shelves of ice. No lifeform can survive here.
 * Boreal (50&#937;): Cool, pine forests. Every land life can thrive here.
 * Desert (50&#937;): Hot, arid climates. Only reptiles, dinosaurs, and insects and thrive here.
 * Grass (50&#937;): Temparate, flat prarie in which every lifeform can live comfortably.
 * Forest (50&#937;): Temperate areas populated with many trees in which many lifeforms thrive.
 * Jungle (50&#937;): Humid forests, product of high rainfall.
 * Swamp (50&#937;): Hot, humid wetlands in which many sea-life, as well as land-life creatures can survive.

Sea life

 * Bacteria (50&#937;): Single-celled organisms (prokaryotes).
 * Amoeba (100&#937;): Multi-cellular organisms (eukaryotes).
 * Starfish (150&#937;): (Starfish)
 * Crab (200&#937;):
 * Octopus (250&#937;):
 * Fish (300&#937;):
 * Whale (350&#937;):

Land life

 * Trichordates (400&#937;): Tricordates are beings with three spinal cords, which became extinct long ago. They have a chance at survival in SimEarth.
 * Insects (450&#937;):
 * Amphibians (500&#937;):
 * Reptile (550&#937;):
 * Dinosaur (600&#937;):
 * Birds (650&#937;):
 * Mammals (700&#937;):
 * Carniferns (unavailable): Carniferns are mutated, carnivorous plants, which can occur only naturally. Having an abundance of insects allows for these lifeforms to develop.

Civilizations

 * Stone (500&#937;): The first level of organized culture.
 * Bronze (1000&#937;): The usage of agriculture allows for higher populations.
 * Iron (1500&#937;): Further advancements allow for even higher populations. This time period represents the dark ages to the renaissance.
 * Industry (2000&#937;): With the beginning of the technological time scale, the use of fossil fuels is having a detrimental effect on the environment.
 * Atomic (2500&#937;): Cities which make use of Atomic energy. Overuse of nuclear fuels can cause radioactivity.
 * Inform (3000&#937;): Representative of present-day modern cities in which the flow of information is important, and computers are a significant part of everyday life.
 * Nanotech (3500&#937;): Cities set in the future in which miniaturisation has taken a predominant role in science and medical technology.

Terraformers
Terraformers are devices used to alter conditions of the planet. If a terraformer is destroyed, it no longer functions, and conditions will revert.
 * Biome (500&#937;): Produces biomes in the area surrounding where it is placed.
 * O2 Genr (500&#937;): Produces oxygen into the atmosphere for life to survive and can lower the planet's temperature.
 * N2 Genr (500&#937;): Produces nitrogen into the atmosphere.
 * Vapor (500&#937;): Produces water vapor, thereby increasing rainfall.
 * CO2 Genr (500&#937;): Produces carbon dioxide, which allows plant life to thrive and can raise the planet's temperature.
 * Monolith (2500&#937;): An extraterrestrial tool that can be used to spark intelligence into lifeforms, making them civilized. The monolith has a 1 in 3 chance of being successful.
 * Ice metr (500&#937;): A large meteor comprised of ice that can be used to create oceans on a dry planet.

Events

 * Storm (50&#937;): Violent storms which originate in oceans.
 * Tidal (50&#937;): Massive waves of water which destroy cities and devolve lifeforms.
 * Meteor (50&#937;): Meteors make large craters and add dust particles into the atmosphere.
 * Volcano (50&#937;): Volcanoes can be used to raise land quickly, in the creation of land masses. They also put dust into the atmosphere.
 * N-Bomb (50&#937;): Atomic bomb detonations that destroy all life and cities in their area and render the land unusable for a long period of time.
 * Fire (50&#937;): Fires destroy all life, cities, and biomes, reducing the area to bare rock.
 * Equake (50&#937;): Earthquakes, used for changing the direction of the magma flow.
 * Plague (50&#937;): Mass disease outbreaks that destroy cities.

Raise/Lower land

 * Raise (50&#937;): Gently raises the land in the area surrounding the cursor.
 * Lower (50&#937;): Gently lowers the land in the area surrounding the cursor.

Examine

 * Examine (5&#937;): Allows you to receive information about a specific area on the map. Pressing  will call up a window displaying any lifeforms and cities which occupy the area, terrain, altitude, and temperature.
 * Special Case: In scenario planets, you must examine the present to open it.
