This year's global celebration's theme is "Forests and Climate Change". The International Day of Forests raises awareness about the alarming rate of deforestation, which not only accounts for 12 to 20 percent of global greenhouse gas emissions through forest fires, but also threatens the livelihood of Indigenous Peoples.
We have been campaigning against deforestation for decades, most recently we have been putting pressure on banks like HSBC to stop funding Indonesia's rainforest destruction.
Together with the Munduruku Indigenous people, Greenpeace also fights against the construction of mega hydrodams in the Amazon.
These pictures illustrate the wonderful biodiversity of forests worldwide, as well as the threats they face.

Whooper swans on a forest lake in Russia. Intact Forest Landscapes (IFL) in Russia are huge forest areas (more than 500 km2 or 50,000 hectares) without settlements, transport infrastructure and economic activities. Forest lands have degraded due to forest fires, logging, and extensive forestry, and the timber industry is now turning its attention to IFL. Proper management of forestry in Russia could protect virgin forests.
