Problem: greenhouse gas pollution Reason: burning fossil fuels Sub-reason: create much carbon dioxide Solution: phasing out fossil fuel Example: not building any new coal-burning power plants Pollution whether it is vehicular‚ electrical or industrial is the main contributor to the global warming. Most of the greenhouse gas emissions come from the burning of fossil fuel for energy such as electricity and transport. When oil‚ gas or coal burns‚ carbon contained within it combines with oxygen

What is Pollution Prevention? Pollution is the contamination of air‚ soil‚ or water by the discharge of harmful substances. Pollution prevention is the reduction or elimination of pollution at the source (source reduction) instead of at the end-of-the-pipe or stack.
