Eutrophication refers to an increase of nutrients in a body of water. Although eutrophication is a natural process, when it is accelerated it is an issue for concern. Many human activities have led to widespread eutrophication in rivers, streams, lakes, and oceans around the world. If left unchecked, eutrophication becomes a problem, severely impacting water quality and biodiversity. Eutrophication was first recognized as a problem in the middle of the 20th century, and many biologists study it extensively in an attempt to prevent further eutrophication of vital bodies of water around the world.

In the sense of a natural process, eutrophication is part of the aging of bodies of water. When a body of water initially forms, it tends to be low in nutrients. As streams feed the body of water, they carry nutrients which foster plant life, ultimately allowing other species to grow as well. A layer of sediment slowly grows, and gradually the body of water will ultimately turn into a marsh or bog, as the sediment displaces the water and the species in the area change.

Define the Superfund program
Weegy: Superfund is the name given to the environmental program established to address abandoned hazardous waste sites. [ It is also the name of the fund established by the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA statute, CERCLA overview). This law was enacted in the wake of the discovery of toxic waste dumps such as Love Canal and Times Beach in the 1970s. It allows the EPA to clean up such sites and to compel responsible parties to perform cleanups or reimburse the government for EPA-lead cleanups. How Superfund Works The Superfund cleanup process is complex. It involves the steps taken to assess sites, place them on the National Priorities List, and establish and implement appropriate cleanup plans. This is the long-term cleanup process. In addition, the Agency has the authority to conduct removal actions where immediate action needs to be taken; to enforce against potentially responsible parties; to ensure community involvement; involve states; and ensure long-term protectiveness. The blueprint for these activities is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), a regulation applicable to all federal agencies involved in responding to hazardous substance releases. Over the past 20+ years, we've located and analyzed tens of thousands of hazardous waste sites, protected people and the environment from contamination at the worst sites, and involved others in cleanup. ] (More)

Some courts hold that an engagement ring is a conditional gift that becomes an absolute (effective) gift only on marriage. Other courts conclude that when an engagement ring is given to the donee, the donee should have full ownership rights in the property. Where do you stand on this issue? Why?
Weegy: My personal stance is that it is a conditional gift given in contemplation of marriage. If the marriage is broken off by the male, she keeps the ring. But if she breaks it off, he gets it back. It is kind of the "if he changes his mind penalty". [ If she breaks it off, she doesn't get to keep a nice present without going through with the underlying reason for the ring. . So essentially it depends on who is at fault for breaking off the marriage. If it is not able to be determined, or if it is a mutual agreement, then the guy gets the ring back. . To me it just seems fundamentally fair. Someone does not buy someone a ring as a gift. They buy it as a wedding ring. So the innocent party in any breakup gets to keep the ring because they have done nothing (or less than the other person) to cause the marriage plans to fall through. ] (More)
