isn't it amazing the way that plants take water and carbon dioxide, just out of the air, and turn it into this green stuff we see here? i mean, it's growing out of nothing. that material wasn't inside the seed it came out of, or in the soil, because the level of the soil is staying the same. The only thing that it appears to consume is water... and the co2 from the air... and it turns it into all sorts of stuff that is plants. it's a miracle. how did the plants ever come to figure out those chemical reactions?? i'm awed. my grass is growing.
