Final answer:
Deforestation, forest fragmentation, and unsustainable resource extraction are three threats facing forests in the U.S. today.
Step-by-step explanation:
Three threats facing forests in the U.S. today are:
- Deforestation: The destruction of forests due to human activities such as logging, agriculture, and urban development. This leads to habitat loss, loss of biodiversity, and contributes to climate change.
- Forest Fragmentation: The breaking up of large forested areas into smaller patches, which increases edge effects, desiccation, tree mortality, and fuel loads. Fragmentation reduces the quality of habitat for many species and negatively impacts forest ecosystems.
- Unsustainable Resource Extraction: The unsustainable removal of natural resources from forests, such as timber, minerals, and water. This disrupts ecological processes and can lead to irreversible damage to forest ecosystems.
