Forests and Climate

Why plant a tree, or even better – many

trees?

Forests and climate

1. The athmosphere keeps the Earth warm 2. Carbon circulates from one stock to another 3. Plants need CO2 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?

1. Atmosphere keeps the Earth warm

HUMAN

Requires a protective layer of CO2 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 CO2 emissions, more CO2 binding

If you eat more than you consume

First getting fatter, gradually negative effects on health

GLOBE

If more CO2 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 forhis vital functions

2. Carbon circulates from one stock to another

-wood and wood products act also as carbon stocks

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

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.

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
