What makes a planet inhabitable?

The conditions of a inhabitable planet varies from species to species, but for most of the species (excluding bacterium and other species that don't need some of the necessities that animals do) on Earth, an inhabitable planet must have water and an abundant food supply. If the planet does not have water, humans cannot live on the planet, and nothing can live without some energy source. If the planet has water, but not nutrients, for example if it's a gas planet with Hydrogen and Oxygen molecules that could combine to make water, but it lacks the nutrients needed for plants and other organisms, it is impossible to say that the planet is inhabitable.As far as scientists know, Earth is the only inhabitable planet.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
