Definition: soil degradation refers to the loss of fertility of the soil, often due to a chemical change.  

Types: water erosion, wind erosion, chemical deterioration and physical deterioration 

Causes: trafficking (by animals as well as by vehicles) and cultivation are the primary causes of this form of soil degradation.

Consequences: soil can degrade by becoming compacted by large machinery and hard-hooved animals, becoming acidic due to a build up of fertiliser or loss of soil nutrients.

Types: sheet erosion, rill erosion, gully erosion, ravine erosion, landslides, and stream-bank erosion.

Causes: natural phenomena such as rivers, waves, glaciers and the wind.

Consequences: loss of newly planted crops. ]]> 2022-02-10 05:42:01 UTC https://padlet.com/armstrongkay/mrjeh2h354vmwsf3/wish/2039532214 Ecosystems decline armstrongkay https://padlet.com/armstrongkay/mrjeh2h354vmwsf3/wish/2039534789 Definition:  Ecosystem decline is principally interpreted as vegetation change.

Types: No types

Cause: habitat loss, invasive species, overexploitation, pollution, climate change associated with global warming.

Consequences: desertification can occur when ecosystems are degrading.

Types: Carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution, and sulfur oxides.

Causes: 
  • The Burning of Fossil Fuels
  • Industrial Emission
  • Indoor Air Pollution
  • Wildfires
  • Microbial Decaying Process
  • Transportation

Consequences:  heart disease, lung cancer, and respiratory diseases such as emphysema

Types: 
  • Arch Dam
  • Diversion Dam
  • Gravity Dam
  • Hydropower Dam
  • Industrial Waste Dam

Causes: no causes

Consequences: dams disrupt the flow of water, flooding some areas and stopping water reaching other areas.
