Industrial and domestic waste are sources of nutrients (e.g. phosphorus and nitrogen) and man-made chemicals (e.g. estrogen) that can enter ponds via runoff after rainfall, pipes or atmospheric deposition, etc. Ponds that are generally shallow can concentrate these chemicals that can lead to changes in their chemical and physical properties. Plants and animals that live in ponds will be affected as well as the water quality of ponds.
Koi are most sutible in man made ponds.

False. Ponds do not form where freshwater and saltwater meet. They are usually man-made.

erosion occurs or it is man-made Water gathers at the lowest point.
Ponds are created through erosion or they are man made. If it was eroded then this take a long time and is especially effected by chemical weathering and just the ground being worn down by the consistent tread of animals and humans. and then it rains, the dip fills with water and overtime animals change the environment and make it into their perfect little habitat. =)
Cultural features are the artificial, man-made features of the environment. Some examples would be buildings, pools and man-made ponds, parks and Golf courses.

It does not really matter what source of water they are living in. As long as the water has a steady food supply and good conditions for them they will live there. Otters have been known to live in cold climates and warm. So food and the cleanliness of the water is really what counts for them.
Most ponds made by man are very simple affairs compared to the real thing. About the only thing they do have in common is water.
Artificial blood is a 'man made' product.It's a special blood cell which can live in people, animals and even sometimes plants.
