The history of the Earth is a history of humanity's constant relationship with the forest. The forest is a refuge, a source of food, raw materials, construction material, a means of transportation, and fuel. Over its existence, humanity has significantly transformed forests: some have been permanently replaced by fields and meadows, others regenerate but are periodically burned and logged. The main impacts on forests are:
- logging;
- fires caused by humans;
- use of chemicals: pesticides, herbicides, fertilisers, etc.;
- industrial pollution;
- reclamation of forest lands;
- intensive tourism, and more.
