Desktop virtualization is software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
Atmospheric deposition of reduced nitrogen onto nutrient-limited semi-natural vegetation (unimproved grasslands, heathlands, blanket bog) can cause a shift in the balance of species in these sensitive systems because the nitrogen has a nutrient effect on plant growth.
When pollution is caused by nutrients and fertilizers, this is called nutrient pollution, and it leads to an overproduction of algae and other aquatic plants. This overabundance of plants and algae causes problems, because they cover the water surface and prevent sunlight from reaching the plants underwater.
