lol you are so stupid.
This is what you have to say, since you don't have much else to say. Your arrogance doesn't add to anything you say, rather it shows you have NOTHING to say.
The local ecology of a place, even if it is an arid desert, is always ruined by human activity that involves the construction of dams and expansion agriculture. The unique biodiversity disappears and is replaced. This is harmful.
It seems like you don't understand what a desert is.
Life forms which live in deserts are much less, than a place which can sustain many different life forms because of the vegetation that is there.
Humans can change the ecology of an arid land, in order to cooler the temperature in that area which in turn would allow for more precipitation to occur.
With more vegetation, more life forms can sustain life there, than in arid conditions where there is
nothing for life forms to feed off of.
How can you rant on and on about ecology and yet not understand this simple concept? Are stubborn or simply thick?
If it was THAT simple, then people wouldn't go to university to get degrees in ecology.
It's funny, since you probably have never even obtained a life sciences credit in highschool, or university, yet you bash others which have.
Let me repeat: biodiversity decreases with agriculture. What is green and pretty does not always equal benefits for the ecosystem. Even an arid desert has unique wildlife that disappears with human expansion.
Again, biodiversity would decrease when you have a forest and that forest is torn down to make a corn field, for instance.
But when you have arid conditions and you grow vegetation, yes your changing the ecology, but its to suit the needs of the country. Life forms will be able to thrive more in areas where there is something to feed off of, rather than arid land where there is nothing.
Yes deserts do have unique life forms, but we are not short of arid land and deserts, but we are short of vegetation and fresh water.
I have now written this in a way that even a child, or an illiterate like you, should understand.
Please, for the love of God, just google "agriculture + biodiversity" and read for yourself before you make an ass out of yourself.
Agriculture in arid conditions, is beneficial for the area. If you are able to grow vegetation and sustain it, it will lower the temperature of the area, attract more life forms there and be overall better for the country and the ecosystem.
Having deserts is not the greatest thing and we are not short of deserts and arid land. What we need to do is sustain vegetative life forms to lower the temperature of certain areas, and this will help for allowing for precipitation to occur.
The water that leaves Iran due to evaporation, maybe, can fall back if we are able to lower the temperature of certain areas by growing more vegetation and trees.
You don't attack the points i made, you just repeat what you've Google and have never even studied one bit.
