Answer: A mitigation bank
Explanation:
Mitigation banks create, improve and conserve wetlands. First set up In 1983, mitigation banks combat the ineffectiveness of systems that were formerly in place to achieve the same task.
In this new system, a mitigation banker buys a site in need of restoration and is given mitigation credits by regulatory bodies. The mitigation banker can then sell these credits to corporates who want to carry out projects that will have a negative effect on a wetland or stream.
