What are the consequences of overexploiting forestry resources?

  1. Overexploitation of forestry resources contributes to habitat fragmentation and can lead to the inability of certain species to survive in their environments.
  2. Reasons for forestry overexploitation include clearing land for agriculture and livestock farming, as well as logging for timber and firewood.
  3. The extraction of wood from forests generally results in improved biodiversity and habitat connectivity.
  4. Overexploitation of forests has no significant impact on plant and animal populations.

    Read Explanation:

    • The overexploitation of natural resources is one of the major environmental problems.

    • These problems arise from the over-exploitation of any species with a high commercial value, without taking into account the population, appropriate use, breeding periods and size of the species.

    • Regarding forestry resources, throughout the world this resource has been overexploited for various reasons, from ploughing for agriculture and livestock farming, to the felling of timber and firewood.

    • The extraction of wood is the start of a series of problems, such as the opening of roads through forest areas, noise, and pressure on plant and animal resources.

    • When these situations arise, habitats are fragmented and some species do not survive in that environment.
