I choose these from our holiday with Grandma in Cyprus last year:
On the one hand, as divers you are at one with nature...the fish swim around you, and will feed out of your hand...it's quite a magical experience. On the other, without the man-made aparatus you wouldn't be there...man and nature in harmony, perhaps
And in this picture...if you look really, really hard, there's a kingfisher on the rusty iron...nature is doing its best to remove this man-made structure which intrudes into the sea, and by so doing creates a beautiful contrast....
