PRINCIPLE OF MATHEMATICAL INDUCTION 65 P(k + 1): a k k + 1 = 5.a k = 5. (2.5– 1) = 2.5k = 2.5(k + 1)–1 Thus P(k + 1) is true whenever P (k) is true. Hence, by the Principle of Mathematical Induction, P(n) is true for all natural numbers. Example 7 The distributive law from algebra says that for all real numbers c, a 1 and a 2, we have c.

8.5.2 Principles for pollution controlThe following principles are used to help control pollution.Polluter pays principleThe polluter pays principle says that whoever is responsible for pollution should pay for the damage caused. It is about economic accountability. Any organisation or individual is responsible for handling and taking care of the waste they produce and should be accountable for any damage that it causes. Imagine a factory that produces many types of wastes that potentially damage the air, water and soil. The polluter pays principle encourages the factory to treat the waste before it is released. If any damage to the environment is caused by the factory waste, then the factory is liable to compensate for the loss of life, damage to health and damage to property and the environment.Precautionary principleFor any activity, there should be an obligation not to cause harm, even if you are not sure of the outcome. For example, if a factory owner wants to discharge wastewater into a river, they should not be allowed to do so if the possible effects of the wastes are not known.

The precautionary principle means you do not release any waste into the environment even if you are not certain that damage will result. It means to be cautious rather than take risks about unknown consequences.Principle of duty of careArticle 44 of The Constitution of Ethiopia provides a guarantee that citizens have the right to live in a clean and healthy environment. But how can this be achieved? All citizens should be actively involved in safeguarding their environment, either by not producing any waste or by properly handling and taking care of their own waste.
In other words, each citizen has an obligation or duty to make their environment clean and safe.
