- Care of the environment against technological impact

- Human Impacts On Environments

Technology
The application of technology often results in unavoidable environmental impacts. For example, given that the purpose of many technologies is to exploit, control, or otherwise improve upon nature for the perceived benefit of mankind while at the same time the myriad of processes in nature have been optimised and are continually adjusted by evolution, there will be disturbance of these natural processes by technology.
This results in negative environmental consequences. Technology has reached an advanced stage in terms of manufacturing products.
These operations result in emissions of different gases which affect our environment.
