Visualizing The Human Impact On The Earth’s Surface

Below is a look at how Earth’s various biomes fare under this ranking system:

Visualizing the Human Impact on the Earth’s Surface

Out of the 14 biomes studied, the least modified biomes are tundra, boreal forests, deserts, temperate coniferous forests, and montane grasslands. Tropical dry broadleaf forests, temperate broadleaf forests, Mediterranean forests, mangroves, and temperate grasslands are the most modified biomes.

Dense human settlements, agricultural land uses, networks of infrastructure, and industrial activities dominate the more highly modified biomes. These lands are commonly subject to five or more human stressors simultaneously, threatening naturally-occurring ecosystem services.

What are Ecosystem Services?

An ecosystem service is any positive benefit that wildlife or ecosystems provide to people, and they can be sorted into four categories:

  1. Provisioning Services: This is the primary benefit of nature. Humans derive their food, water, and resources from nature.
  2. Regulating: Plants clean air and filter water, tree roots help to keep soil in place to prevent erosion, bees pollinate flowers, and bacterial colonies help to decompose waste.
  3. Cultural Services: Humans have long interacted with the “wild” and it, in turn, has influenced our social, intellectual, and cultural development. However, the built environment of a city or town separates man from nature and ancient patterns of life. Ecosystems have long served as inspiration for music, art, architecture, and recreation.
  4. Supporting Services: Ecosystems contain the fundamental natural processes that make life possible such as photosynthesis, nutrient cycling, soil creation, and the water cycle. These natural processes bring Earth to life. Without these supporting services, provisional, regulating, and cultural services wouldn’t exist.

A Delicate Balance

With each encroachment upon habitat, the potential increases for humans to inadvertently upset the careful balance of ecosystem services that have nourished the processes of life on Earth.
