Namibia is the 88th country I have visited.

It has 2,533 794 inhabitants [2017], occupying 823 328 sq km.
London has 8,787,892 [2018] population[I have looked up several sources  and the figures are different],  living on  1,579 sq km.
It was surprisingly cold [20 C]  when we docked in Walvis Bay,the town that has nothing nice to say for itself other than it has the largest and most important port in Namibia.
Treasures of Namibia was the name of the tour I had chosen to participate in,as I very much wanted to see the prehistoric  Welwitschia Mirablis Plants unique to Namibia, and  so called after Welwitsch,a Portuguese botanist,born in Austria.They produce two leaves only in their lifetime.The two large woody leaves  lie on the ground, animals nibble at them,but cannot swallow. There is a conelike structure  between the leaves,very hard to the touch.The plants have a lifespan of 500 - 2,000 years.
We had to privilege to see lichen plants,too.Lichen is a "symbiotic association of a fungus and an alga,"it is a kind of crusty patch or a very,very low bushy growth that comes to life  in contact with water,as the tour guide had demonstrated.
Then there was the Dune 7 of the Namib Desert, at about 55 million years  the oldest in the world,where tourists come to wallow in the soft warm sand,and the  surreal moon landscape where Mad Max 2 was filmed.
The Namib Desert is a home to  The Palmato Gecko and The Desert Sidewinder.
The tour guide informed us  that in the arid nastiness that rarely sees water live various animals including giraffe,zebra and baboon, and told us to watch put for them.
My eyes were peeled yet I saw nothing and expected to see nothing.I told Okey,the very likeable guide, I did not believe an animal could live without water or food and therefore no animals other than those that live under  the ground can live in the Namib Desert and the surrounding land.Maybe, I said, years ago, when there was water and living edible plants, but not now.He was quite taken aback,I do not think any-one had ever doubted his word,
We passed the uranium mine owned by the Chinese,all uranium is shipped to China to use for nuclear energy.There is an 80 km long pipe that supplies water for the mine.The Chinese are paying  for it all. Any work [ the little we have seen] being done in Namibia is done in partnership with China.Should Chinese banks call it in, they would own the best of  Namibia,if not all of it.
We passed salt mines,they produce 500 000 tons of salt a year, 80% being exported to South Africa.
We stopped in a delightful oasis for the most excellent drink, delicious bubbly and very,very tasty snacks,included in the tour price.They also sold  incredibly looking oh so tempting cakes,but I left my debit card in the truck,so could not buy any.The almost five hours of the tour passed so very quickly.Even a bumpy ride was somehow an acceptable  part of the whole experience.
And as we were saying good-bye, I was so very happy to hand a bag-full of clothes to Okey to give to his wife.Not everything I wanted to leave,but most of it, I simply had no room for it all.   Oh,and the weather inland was at least 30 C,The Namib Desert is never cold.
