Earth

Earth, also known as Terra, is the home planet of humans located in Sol. It is filled with relics of cultures long-gone, which is perhaps its only redeemable feature. The planet is renowned for its variety of rubbish. Some of the rubbish is valuable, and thus Earth has become something of a mechanic's paradise.

Geography
Earth's surface is 85% water. What surface remains is typically arid desert or wasteland. Open plains are broken up by mountains of garbage and towering rock formations. Other areas that were formerly forests are seas of tree stumps as far as the eye can see. Beaches are common, but the soft sand is mixed with shards of glass and sharp pieces of aluminum.

Vast trenches, quarries, and strip mines run across the Earth's surface. Much of civilization has moved underground, using abandoned quarries and mines as expensive apartments. Apartments built into the sides of old quarries are the only apartments that offer windows peering into the outside world.

Toxic Conditions
Earth's temperatures are too warm for most humans to comfortably withstand. Most have left. Water levels are higher than they ever have been, so much of the surface has been lost.

However, what remains of the surface is scarred by war, mining, human construction, and other such activities. The surface is filled with junk and debris from not only natural disasters but overflowing human landfills and junkyards.

Rain is highly acidic and can cause damage to structures and exposed skin.

Due to the high carbon content in the air, the atmosphere is toxic and unbreathable to most species. Some species adapted to high carbon dioxide atmospheres are able to handle it, but every other species requires a form of mask.
