Before humans arrived, the world was a natural environment with diverse ecosystems and wildlife. There were no human-made structures or cities, and the land was mostly untouched by human activities. The climate and landscapes were shaped by natural processes, and animals roamed freely without human interference.
Less than 3% of the world's land surface remains unaffected by humans. This includes areas like remote wilderness areas, deserts, and high mountain regions. Human impact, through activities like agriculture, urbanization, and infrastructure development, has significantly altered the majority of the Earth's land surface.
For humans to be able to use nitrogen it must be converted from N2 (g) to ammonium (NH4^+), nitrate (NO3^-), or organic nitrogen. Nitrogen is the majority of the air we breath but it is relatively inert due to the triple bond between N atoms.
Humans shape the Earth by altering landscapes, climate, and ecosystems through activities like agriculture, urbanization, and resource extraction. These changes interact with natural forces like weather patterns, plate tectonics, and natural ecological processes, leading to a complex interplay between human activities and the natural world that shapes the Earth's environment.
Humans use land for agriculture, urban development, and infrastructure like roads and buildings.
Modern humans, Homo sapiens, have been on Earth for approximately 200,000 years. However, the earliest human-like ancestors, such as Australopithecus, date back around 4 million years.
Just as it is now, very cold and covered in ice and snow except for the dry areas which are just very cold.

Life in America before Europeans arrived was described as pretty primitive. These natives relied only on nature and how they could use it.
it was a great lifetyle
It's not a real thing
the soldiers dug the trenches them selves so they just looked like fields.
had, we use past perfect because we talk about an activity that was before you arrived in the past, so it's like a prepast tense
Rome is in Europe. Its inhabitants were always predominantly European.
Humans first arrived in what would become Kuwait around 100,000 years ago and parts of Kuwait were part of Ancient Sumeria. It's not like somebody planted a flag and said "I Explorer X have discovered Kuwait" like Europeans did when they arrived in the Americas or Australia.
Full of activity
well, without humans, the world will have no problems ,like global warming, pollution. But there won't be any pluses like, cures, and many animals would be injered and would get infected, but i guess that's natural. Before we were here that's what happend. Good question. I hope i helped you get an idea. 2nd answer Don't know. How would we know if there is no humans.
god is a bit of both because he created the world to treat humans however if he is not worshiped and there is many sins he like before will create a rapture
