Description: Explore fossils, stone tools, and discuss the history of life and climate with experts. What can fossil mammal teeth tell us about changes in Earth's environments over time? What were Earth's climates like thousands or millions of years ago? What do we know about early humans and how did our species come to dominate the planet? At our stand, you can explore these questions and climate history with specialists from the University of Helsinki.

Climate Change, Biodiversity Loss, and Future Forests

Organizer: Faculty of Agriculture and Forestry
Description: How will climate change and the loss of biodiversity affect the forests, the carbon assimilation of forests, and the organisms living in them? Further, will the use of wood as part of sustainable building have any impact on the well-being experienced and measured in humans? What kind of tools are currently used to measure forests and what will they be like in future? At this stand you will be able to take methane and carbon dioxide measurements, hug different kinds of trees, and find out which is your favorite kind of tree. You will also be able to look at the light produced by tree leaves, which is invisible to the human eye, and which gives us an indication of how the tree is doing.  We also have information on various forest insects and their secret social life, looking at insects through a microscope, learning to identify where insects have been feeding, and a detective assignment where you can learn about the color vision and behavior of pollinating insects with the help of UV lamps. These activities are suited both for children and adults.
