Maybe. But then we might be placing too much faith in science. I don't think our planet will fall into ruin though, it might change and many organisms may fail to adapt but thus is the nature of the world, it's happened before and will happen again.>>658
No, generally that refers to creating an atmosphere nutrients are never really mentioned. Creating an atmosphere itself is next to impossible for us, enriching the soil of the planet is another thing entirely. The composition of the soil is quite important and even now is only really a novel field of serious enquiry. The reason that we use so much fertiliser to grow things is because we didn't really understand this and so the way we grew crops was removing nutrients from the soil and damaging the organic matter beneath it so we keep having to use fertiliser.
