How does soil pollution affect the ecosystem?
Soil pollution has bad consequences: It impacts food security both by impairing plant metabolism and thus reducing crop yields, as well as by making crops unsafe for consumption by animals and humans.
How does soil act as a carbon sink?
A study just published by the Joint Research Centre (JRC) in Nature Climate Change shows that soils can be a net sink of greenhouse gases through increased storage of organic carbon. Plants absorb carbon dioxide from the atmosphere and stabilise it in the soil.
How does soil pollution affect soil productivity?
The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield. The contaminated soil is then used to produce fruits and vegetables, which lacks quality nutrients and may contain some poisonous substance to cause serious health problems in people consuming them.
What are the cause and effect of soil erosion?
Soil erosion is a type of soil degradation that naturally occurs on all land. There are many causes of soil erosion, most of them being the same as other forms of erosion: namely water, ice, wind, and gravity. The effects of soil erosion can include the loss of fertile land to floods or water pollution, among others.
What happens when soil erodes to dirt?
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
What are the effects of soil respiration?
Inherent factors that impact soil respiration, such as climate, cannot be changed. Inherent soil respiration rates depend on amount and quality of SOM, temperature, moisture, salinity, pH, and aeration. Biological activity of soil organisms varies seasonally, as well as daily.
How is soil erosion harmful?
The effects of soil erosion are not just land degradation. It has led to a drastic increase in pollution and sedimentation in rivers that clogs the water bodies resulting in a decline in the population of aquatic organisms. Degraded lands lose the water holding capacity resulting in floods.
