aaah o.k thank you very very much.
but you know just like the way there's the common green grassland that is very beneficial to animals and humans (by allowing humans to grow crops,etc,etc)...
is it possible, that there could be other types of basic foundation
example: on a high hill on one side it was all green grassland (like normal), but then right next to the pasture, there was another section. the ground on this side was wet,boggy,full of natural herbs,etc. one part of this section, there was a certain plant that looked like a yellow Sponge that you find in the sea.
o.k: so grassland for human use is beneficial for crops,living,wildlife,etc,etc.
now take the rainforest amazon for example, and the tribes living there. the people (most of the tribes) there live a peaceful and loving life. but from what I read the life expectancy
so take this example:
amazon rainforest:
- lots of rain, full of nature, green, plants,animals,wildlife,etc. all that is good.
but the tribes living there may have a low life expectancy because certain diseases from the wild (this is just from one source I read).
now think of the Sponge found in the sea. certain sponge's have natural antibiotic activities. but lets say a certain Sponge like Porifera evovled into a new certain grassland, and this certain grassland by tribes walking on it,etc instead of lets say a certain grassland that could cause diseases.
my point is:
think of there being no grassland. and in South Africa drought is a major problem. but then add the grassland to drought areas in South Africa. the grassland may help the problem.
so the Sponge or lets say some moss.
and in certain areas, a type of moss/fungi integrates with the grassland, and as a result that fungi/moss/etc helps protect nature but also promote growth and all that.
please note: when I said the Sponge idea, that was just a by the side concept/to give you an idea. so you replace Sponge with something else lets say.
I apologize if the question may be silly or whatever but its just of great interest and I have no knowledge what so ever and would just like to learn more . thanks.
