Forests and Climate Why plant a tree, or even better – many trees?

2/(12) Forests and climate 1.The athmosphere keeps the Earth warm 2.Carbon circulates from one stock to another 3.Plants need CO 2 and they bind it at the same time 4.How did this happen? 5.Forests are important: let’s increase the amount, manage and use them in a sustainable way 6.Multiple values of forests -what does a forest mean to you? 7. What can we do?

3/(12) 1.Atmosphere keeps the Earth warm EARTH ATMOSPHERE

4/(12) HUMAN Requires a protective layer of CO 2 and other gases around it to retain a sufficient temperature on the Earth THE SITUATION GETS WORSE UNLESS SOMETHING CHANGES SOLUTION : less food, more exercise SOLUTION : less CO 2 emissions, more CO 2 binding If you eat more than you consume First getting fatter, gradually negative effects on health GLOBE If more CO 2 stays in the atmosphere than to which the current ecosystem is ”used to” First, the temperature on the Earth arises, gradually the effects of the elevated temperature starts to show Needs food to get energy for his vital functions

5/(12) 2. Carbon circulates from one stock to another -wood and wood products act also as carbon stocks

6/(12) 3. Plants require CO 2 and they bind it at the same time light (energy) carbon dioxide CO 2 water H 2 O oxygen O 2 sugars oxygen O 2 carbon dioxide CO 2 energy PHOTOSYNTHESIS : BURNING :

7/(12) CO 2 BEFORENOW THE GOAL TIMELINE 4. How did this happen? 1 ton CO 2 1 m 3 wood

10/(12) 6. Multiple values of forests -what does a forest mean to you?

11/(12) 7. What can we do? USE WOOD IN CONSTRUCTION PLANT NEW TREES!!! MANAGE AND PROTECT FORETS DRIVE LESS RECYCLE WOOD PRODUCTS USE WOOD AS BIOENERGY

12/(12) What can I do? Save energy… ride a bike use public transport instead of using own car travel by other means than airplane change energy saving lamps remember to turn off lights and electric devices when you don’t use them –also stand-by mode! have only a quick shower and avoid unnecessary use of water eat less meat prefer local products …and plant a tree.

13/(12) THE ROLE OF FORESTS IN CONTROLLING CLIMATE CHANGE Increasing and growing forests in a sustainable way and using them in multiple ways Substitute non-renewable materials with wood Recycling wood products
