We look at how human activities negatively impact vegetation, ways to improve soil quality, and the role humans play in altering the physical environment. Please explain how negative activities impact the environment and share examples of these concepts, especially as it relates to your local area.

Human activities are impacting the quality and quantity of topsoil, which has humus content for the development of a good vegetation by the process of mass extinction and deforestation of trees and modification of the environment of agricultural practices man has altered the soil contents.

All these have negatively impacted the soil and caused desertification, acidification and made barren wastelands, as in the case of Sahara desert which was once lush green filled with water sources.

My local area to is affected by the same type of man-made disaster, as the river bed which used to be placed where vegetables were grown now seems like a stretch of stinky channel covered with deposits of harmful toxic gases and foam of industrial pollution and toxins released every day by the industries and households nearby.

Thus destroying the oxygen levels of soil and making water unfit or contaminated for consumption.
