Forest Conservation covers a broad range of economic, educational, legal, political and preservationist activities to safeguard the environment for people, animals and future populations. Forests provide essential habitats for many plants and animal species. They are also places of natural beauty and scientific interest, and they play an important role in replenishing the Earths atmosphere by replacing carbon dioxide with oxygen and filtering out airborne pollutants. Educational activities include raising public awareness of the environmental, social and cultural impacts of deforestation and ecological change. A
related, though sometimes more controversial approach is "eco-tourism", which encourage new volunteers and spread awareness through walks, tours and site visits. Economic and political measures include supporting governments, communities, workers and land-owners in maintaining forests and regulating logging activities, or finding non-destructive solutions for utilising local forests. Exonomic measures can also include trade sanctions and legal action against individuals and organisations responsible for logging and deforestation. Park rangers and conservationists may carry out agricultural work to replant forests, protect soil, improve growing solutions or actively remove invasive species and surveys to monitor chaging climates and populations.
