I believe it could be both. A natural loss of habitat may be caused by flooding or a forest fire for instance. - A man made loss of habitat could be caused by building a highway or cutting down a forest.
Anthropogenic effects, processes or materials are those that are derived from human activities, as opposed to those occurring in natural environments without human influence.
Uniformitarianism is the assumption that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past. Thus the processes and results of a volcano erupting now are assumed to be the same as or similar to volcanoes of the past. This allows us to interpret the geological structures deposited by fossil volcanoes and infer the processes that caused them.
Chlorofluorocarbon (CFC) gases used in refrigeration
Hi how are tou
No it is not. It is caused by man made CFC's.
yes its true!
Ozone layer is caused by natural processes. It is formed by UV.
Ozone holes are the thinning of ozone molecules. This is caused by man made or natural processes.
The ozone depletion is caused by natural or man made processes. Man made process is the releasse of CFC's by humans.
A swallow-hole is a natural hole in the ground, usually found in karst landscapes, caused by various geological processes.
The thinning of ozone layer is the depletion of ozone molecules. It is caused by various man made and natural processes.
It was caused by natural Earth processes. The movement of the Indian sub continent into the Asian continent driven by mantle convection.
Yes, erosion is caused by the factors such as wind action, river and stream processes, marine processes (sea waves), and glacial processes, which is all due to gravity.
The hole in the ozone layer is the falling of the concentration of the ozone layer below a certain concentration. It is caused by various man made and natural processes.
