All of them.
I don't mean to be flip about this, but think about it. If there were any conditions on Earth that weren't conducive to life, we wouldn't be here, would we? So just about any condition you can think of--temperature, pressure, chemistry, you name it--allows us to survive.
Probably, if we survive a climate disaster that threatens us if we continue to pollute the Earth at this pace.
Because just like a baby needs its mother to survive, we (and all life on Earth) need Mother Earth to be able to live, too. We also owe "her" that, since "she" gave us life and all that we need to sustain us. We protect the earth because she is the only planet that protects us and keeps us safe.
Us humans are rather finicky about the conditions we can live in. It can't be too hot, it can't be too cold, there has to be water to drink and air to breathe. The gravity has to be about what it is on Earth and so on... As far as we know at the moment no, as there are currently no planets that we know of with the necessary temperature, gravity strength and atmospheric composition for humans to survive. We can only know this about the planets in our solar system however.
The Ozone helps the earth in many ways, most likely too many to put on a list but the most important are, it protects the earth from meteors. Also it help hold in oxygen so the earth can have life.
Earth has many things which are necessary to sustain life. Water is essential for life, as well as an atmosphere with abundant oxygen and it is the perfect distance from the sun to provide us with enough heat and energy to survive.
Oxigen from trees
they give us energy to survive
important of afforestation is to save our earth,to survive us,to save the earth from the pollution.
Earth's rotation
We can easily survive here on Earth, because this is the planet that we evolved in; we are literally "made for" planet Earth. So how do we survive elsewhere? By taking a little bit of Earth with us. On Earth, we have the proper amount of air, water, and comfortable temperatures; in space, we build space stations or wear space suits that recreate our Earthly environment around us.
It is the only planet with the recourses necessary for us to survive.
by helping plants grow to let us survive
No!! Insects are needed for us to survive on earth! They help create the carbon dioxide on earth.
The earth help them to survive by providing food, wood, straws, that was needed. food to eat wood and straw to build their homes.
Because earth supports life, she provides us fruit bearing trees for food amd water to drink. Earth is the only planet that provides what we need to survive
earth provides oxegen wich we breath. also the vacum would kill us you
Probably, if we survive a climate disaster that threatens us if we continue to pollute the Earth at this pace.
