Welcome to the twelfth Daily Field Note! Here you find the top post of the day, one covering each scientific field that is included by Geopolis. Since these authors put a lot of effort in writing a good post they surely deserve the extra exposure.
Geopolis is a project to promote and connect authors who write in the fields of global sciences. Upvotes are currently worth more than $1,50 so don't hesitate to get involved or become a member for higher rewards! You can read more about the project and how to join here:
Subjects curated by Geopolis are Geography, Anthropology, Ecology, Geology and certain branches of History.
Geology: Beautiful day for geology
Now you can go on a field trip without leaving your chair! 
Went to an interesting outcrop today on the side of the road. My entire class participated in inspecting the rock face that had so many aspects to it. You can see the folding of the sandstone in the photos. We had a beautiful day with clear skies and a bright sun. The best part is that we were right by a river that had some rapids.
Geography: The Crisis: Global Mass Migration
A nice summary on the current migration crisis is given to you by 
History has it that humans have been migrating from the beginning of creation. Since the end of the last ice age, humans have wandered as far as they could exploring every nook and cranny of our world. The current trend of migration is the migration of people of developing nations to developed nations, that is Least Economic Developed Countries (LEDC) to More Economic Developed Countries (MEDC).
International Migration is at his peak and shows no indication of slowing down anytime soon, this is because of the challenges some parts of the world are experiencing; terrorism is at its peak, civil war has made many people to flee their country of residence, oppressive regimes, financial crisis among others.
Ecology: That time mushrooms saved the world
An entire post about mushrooms? It is possible and actually very informative. Make sure to read this post from 
This is an ancient, primitive history. From an Earth that had already suffered many apocalypse and that was heading, slowly but decidedly, towards another glacial collapse. An Earth of dense air, where carbon dioxide was disappeared and oxygen reached such high levels that it is difficult to imagine.
Where the centipedes of two and a half meters dragged their bodies without worries and where the 75 centimeter dragonflies plowed the skies of half a planet. But, above all, an Earth where wood reigned. A tyrannical reign that pushed the world towards the fourth glaciation. As Andrew Tomes explained, that's how mushrooms saved the world.
Anthropology: Sumerian culture that valued the literacy
Sumer is one of the most ancient civilizations on earth. It is well known that the Sumerians began to build cities and roads 7,000 years ago. They are among the first in the history of mankind to give up tribal housing and start building real homes. Today we have some artifacts from their ancient culture, but that's part of what scientists have discovered today.
