Question

what is human activities? How many types explain?

Answer 1

Humans rely on ecosystems to supply food and other necessities for a healthy human life. Certain human activities have had a devastating impact on ecosystems, however. From pollution to overharvesting, the damage and exploitation of wildlife and natural vegetation by humans has left some ecosystems in bad shape.

Ecosystem Pollution

Many byproducts of industrialization have harmed ecosystems. For example, burning coal to produce energy releases chemicals like sulfur dioxide. Such chemicals in the air lead to acid rain and acid deposition, which can harm plant and animal life, especially as it acidifies aquatic ecosystems. In addition, liquid chemical runoff from human activities can negatively impact ecosystems. Such runoff is not just produced by big industrial factories. Zinc and lead runoff from lawns, driveways and sidewalks in residential areas can damage ecosystems.

Urban Sprawl

Urban sprawl is the ever-increasing spread of cities out into formerly rural areas. Clear-cutting and deforestation have occurred in order to accommodate the push of urbanization into rural regions. Besides resulting in loss of forests and other vegetation, such actives lead to habitat fragmentation. When roads, homes or even vehicles cut through the original ecosystem composition, animals can be cut off from a large part of their habitat and, by extension, their population.
