What are the dangers of over utilization of natural resources?
While natural ecosystems are essential for plant and animal growth, overexploitation can lead to severe issues like global warming, food insecurity, climate change, and mineral depletion.
What are the impacts of over utilization of resources?
The way we use resources provokes often irreversible ecological change. Extraction and processing of non-regenerative raw materials are often energy intensive activities involving large scale interventions in ecosystems and the water balance and result in air, soil and water pollution.
What are the consequences of using land as a resource?
Agricultural land use may also result in loss of native habitats or increased wind erosion and dust, exposing humans to particulate matter and various chemicals. Some land uses can accelerate or exacerbate the spread of invasive species.
What is the main cause of overexploitation?
Overexploitation occurs if a water resource, such as the Ogallala Aquifer, is mined or extracted at a rate that exceeds the recharge rate, that is, at a rate that exceeds the practical sustained yield. Recharge usually comes from area streams, rivers and lakes.
What are the consequences of over utilization of surface and ground water?
OVER-UTILIZATION OF SURFACE & GROUND WATER The increased extraction of groundwater far in excess of the natural recharge led to decreased groundwater level. The erratic and inadequate rainfall caused reduction in storage of water in reservoirs. This also led to decrease of groundwater.
How does overexploitation affect the environment?
Overexploitation or overfishing is the removal of marine living resources to levels that are too low for sustaining viable populations. Ultimately, overexploitation can lead to resource depletion and put a number of threatened and endangered species at risk of extinction. See also the article Species extinction.
What are the problems of land use?
Current land use challenges include urban sprawl, infrastructure congestion, accessibility to services, urban density, urban regeneration and negative externalities, such as pollution and the displacement of population due to excessive house prices and land hoarding.
What are the causes of over exploitation?
Often overexploitation occurs when natural populations are harvested for food. A classic example was the persecution of the passenger pigeon, which once was the most abundant bird in North America.
What are the consequences of overexploitation?
What is over exploitation of land use?
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource.
