Deforestation

By: Reuben Harlin

Hypothesis

Deforestation causes harm to Earth's function in many ways

Defintion

Deforestation: The action or process of clearing forests (Merriam-Webster)

Deforestation for Mining

Mining impacts affect up to 33% OF GLOBAL FOREST ecosystems

  • High demand for earth minerals causes more forests to be cleared for mining
  • Affects the ecosystem by driving out natural wildlife
  • Mining can contaminate soil and water, causing the land to be useless after the depletion of minerals
  • 80% of mining is done in 10 countries, with rainforests suffering the most damage (WWF)

Deforestation and Earthquakes

DEforestation can increase THE chances of an earthquake

Deforestation can cause harsh changes to already sensitive land, making earthquakes more likely. The combination of deforestation and earthquakes can lead to massive landslides, which can lead to soil erosion and reroute waterways and flood farmland (Than)

Soil Erosion due to Deforestation

52%

Studies show that deforestation reduces soil organic matter by 52%. This decrease means the soil is unable to store and supply nutrients to plants and crops.

Deforestation & Fossils?

ARE These things related?

Deforestation can cause fossilization gaps. Disruption of soils that favor fossilization can alter our ability to estimate the timeline of fossils!

Deforestation and Oceans?

Natural Disaters & Man Made Ones

Tornados

Tornados can cause the same effects as man made deforestation can. Many places seek to RE-forest after a tornado is significant damage is done.

How Can I Help?

  • Purchase items that have the "CheckTree" label that shows environmentally friendly production (Perugia)
  • Choose sustainable foods that due not require deforested lands
  • Support Re-forestation
  • Recycle! Recycle products that are made from trees that can be reused instead of relying on new products that require deforestation.

What Are Some Solutions?

  • Implement reforestation and agroforestry
  • Lobby for more areas to become protected lands, like national forests
  • Choose more environmentally friendly products
  • Advocate for stronger laws protecting forests
  • Advocate for indigenous people who are often caretakers of land as they live and work there

Deforestion on earths functions

Deforestation has major effects on everything from agriculture, oceans, landscape, wildlife, people, global warming, and even natural disasters. Considering everything involves land and resources, deforestation has an effect on almost everything. Deforestation is the most impactful action that is affecting our earth's functions and systems.
