There are many purposes for having dams and reservoirs, and there's not really a definite answer to this question. However, if I would have to give my best guess, the two main purposes are to generate hydroelectricity from water spinning turbines within the dams and also to hold back water from a populated area
Western coast of Europe is the most affected. Back in the day they used to called westerlies the "anti-trade" winds because travelling cross atlantic took longer.They affect the climate because they carry remnants of tropical storms formed in the Caribbean and Eastern USA across the pond, which eventually reaches Spain, France and the UK (and to a certain degree the Netherlands). They also carry warm winds and waters.
There are four physical systems: the atmosphere, the biosphere, the hydrosphere, and the lithosphere. The physical processes on Earth create constant change including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

The correct answer is negligent.
In tort law, negligence refers to when a person or organization unintentionally causes harm or injury to others. For instance, if a day care facility has rotting mold (that the staff is not aware of) that affects the children's health and makes them ill, it is a negligence on the part of the day care center. Another instance of negligence is having your neighbor's dog escape their house (without your neighbor's knowledge) and then proceed to enter your house to attack your cat.
