Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Answer:
Selective breeding is used to promote the benefits of both animal and plant breeding inheritance. It is essentially done by controlled breeding. However, it has its own set of disadvantages, like any other agricultural method-although it is supposed to offer benefits to society. If you want to selectively breed your crops and cattle, weigh them down and decide whether that’s a good way for you.
No company patent is required.Anyone working in farming can start breeding selectively whenever they want. It is a way for him to create more profits every year, as he can grow animals and plants with different characteristics such that they can be generated over centuries, which is good for businesses. And since he is free, he only needs to be knowledgeable and well equipped in the process to achieve the best result.
It makes higher profit possible.Selective breeding encourages more beneficial plant and animal characteristics for farmers. If they have selectively bred cows, for example, these animals can produce more milk than the typical cows and the gene can be transferred to their descendants. If the method is used on crops, more than the typical ones will also be grown. Promoting these advantages will certainly increase their product’s market value. Selective breeding is certainly an perfect choice for farmers who are in a major company.
