Map of a dead Earth without biomass or ice

Earth is the cradle of civilization and the only known home of life in the universe, but it is under threat. Climate change is altering our planet rapidly, and the effects are accelerating.

In order to save our world, you must slow the increase of atmospheric gases and return the planet to a stable sustainable pattern. Preferably, before any massive ecological die-offs or societal collapse.

About

Earth is the third planet from the sun, where humans live, and one of the five worlds available in TerraGenesis for free (unlocked after achieving Victory on Venus, which in turn is unlocked by Victory on Mars). It is one of two planets that already have cities when the game starts (unless count Native Civilizations), the other being Lethe..

Information for Terraforming

Earth starts with 12 cities positioned and named after major regions of the world, such as North America, Western Europe, Central Asia, etc. The cities have no terraforming buildings — not even a basic Hab Unit. However, due to Earth’s habitability, there are large starting populations already spread out on the surface around each city.

Players will be faced with a couple of immediate problems:

• Temperature permanently increases by 10 mK/min due to an effect titled 'Climate Change'. If it is not compensated for, it will cause ice to melt and make the sea level become too high. A Cooling Plant I and Cooling Plant II can quickly solve this issue at the start of the game.
• Biomass is the main reason for Earth being considered hard, as it’s falling at an increasing rate, and already at over 1,200 Mt/min because the planet's inherent biomass growth features is insufficient to support the population. With no Habitation buildings to feed the large population centers, biomass management will be the first priority. A silly way to solve this issue is to just wait until loss of plant-life kills off everyone, from there the biomass will start to regrow without the massive population. This problem does not apply to Beginner mode or on Biospheres.
  

  

  An example of Earth natives

• If playing with the Biospheres feature, the plant species will be producing excess oxygen, not used up by animals species. Build a couple of O2 Filters. Also, if you don't stabilize Temperature, all of the species will go extinct, and that will affect the terrestrial plants support number. If that number falls below 9, Earth will still become uninhabitable.
• In Expert mode, there is a permanent "Population Maintenance", which causes the credits to fall. Also, if using Biomass, there is a permanent -24 ppm O2 decrease titled “Stable Biosphere“.

Here are some tips to solve issues around plummeting biomass:

1. Spend some GP (Genesis Points) to quickly research coral reefs, which one will need to build a lot of to offset the plummeting biomass. GP can be earned by watching ads coming in from transmissions. Since coral reefs require Algae Colony and Kelp Forest, make sure to have more than 30 GP (Exact numbers will vary. FFI and UNSA will need less than Horizon Corp, for example.).
2. Be sure to spend a lot of real time in the game in order to get a lot of sports leagues (The League event) to drastically increase revenue, so you can quickly build the Sky Farm satellite, which will make biomass irrelevant and instantly save the planet. Also, one should build the Soletta satellite to stabilize Temperature. Those Satellites only avaliable in Normal Difficulty.
3. After building Coral Reefs, it may be worth spending some time playing to get the Coral Reefs upgraded to Level X by the Wonder of World event to drastically slow the decrease of biomass.
4. Assign governors that reduce biomass consumption to the most populated cities (South Asia, East Asia, and so on) to borrow some time that can use for researching and building coral reefs.
5. If you are lucky, Eureka events can make Coral Reefs occur faster (which one would need it to occur three times to almost instantly research Coral Reefs.). After that, build at least three Coral Reefs, and hope that get upgraded by the Wonder of Earth event. This is, however, very rare and is fully dependent on RNG.

Earth has 78 species when start a new world, the most out of all worlds along with Lethe. Click the links for more info on biospheres and phyla and traits.

Trivia

• On Earth, Culture Points spend towards Unification instead of Independence to achieve victory, although this is merely a name change.

• The starting date (and mission date) displays in the current date. (On standard network time)

• When leaving the game save of Earth alone for a long time, it will become a lava world due to climate change, which increases the temperature by 10 per minute, unless the temperature doesn’t rise.

• For some reason, Sharks were written with genetic code as "mammals", despite clear fact that they are fish. So, if you care especially about realism, create a new shark species that is a fish.
  • Additionally, whales are classified as "herbivores", even though all whales are carnivorous. This could possibly be due to the fact that they mainly prey on krill instead of larger herbivores.

• The starting Biomass was increased from 630,000 Mt to 750,000 Mt. But the real amount is about 550,000 to 560,000 Mt and growing.

• Earth will be swallowed or melted when the sun turns into a red giant about 5 billion years in the future.
• Earth's real life temperature is 287,820 mK, the oxygen is about 209,460 ppm, and the pressure is about 101,325 Pa. The reason for these differences is due to rounding made by the devs.

  Oxygen	209,460 ppm
  Water	1,103,400 cm (7,000 frozen in ice)
  Biomass	560,000 Mt

• 14 °C is equal to 287.15 Kelvin, not exactly 287 Kelvin. Once again, rounding is likely involved.
• Earth's average sea level is about 3.65 Kilometers, but the deepest point is about 11.4 Kilometers, which is the Mariana Trench.
• In Southern Africa, there is a "Plague Outbreak -1,000" in the population tab.
• Earth has a special event that spawns a native civilization. This event does not happen on any other world.

SPOILER ALERT — Victory Text

Unity.

For thousands of years, that single word has been the goal of conquerors and politicians, scientists and poets, maniacs and saints. But now, finally, the nations of the world and all [number] of people within them are united and focused toward a common goal: the advancement of humanity and our exploration of the universe.

If Earth still habitable for humans: Looking back on your life, you can remember dark times. Famine and drought, disasters of ever-increasing devastation. Climate change threatened to ruin the cradle of humanity, as if the ground on which we stood was rebelling against us. But through focused effort, great expense and the help the scientists from across the world, you were able to calm the beast, and the Earth was saved.

If Earth isn't habitable for humans: The cradle of humanity, the only known home of life in the universe, can no longer support us. In our youth and arrogance we ruined the garden in which we were born, and nothing can change that now. But with focused effort, great expense, and the help of scientist from around the world, perhaps we can one day walk freely on the surface of Earth again.

Under your leadership, the [faction] has become the foremost authority on interplanetary hominization. New societies are springing up on world after world, each modeled on your [description of culture]. You've effectively settled the terraforming debate as well, encouraging/discouraging terraforming efforts on other planets by your own example.

A new chapter in the history of humanity is unfolding on Earth. Will you stay to continue on it, or move on to new worlds among the stars?
