A growing number of people feel that animals should not be exploited by people and that they should have the same rights as humans, while others argue that humans must employ animals to satisfy their various needs, including uses for food and research. Discuss both views and give your opinion.

The diagram illustrates the functioning of an implant created to generate electric energy using the moving mass of the sea waves. Overall, the process starts with the wave entering a sea-level chamber and ends with the generation of electricity. The whole procedure does not imply repetitive stages but goes on as a continuous process throughout the whole duration of the sea swell, both when the waves approach the implant and when they slide away. As the

first

wave arrives in the lower chamber, it generates a positive pressure within it, which permits the air to flow inside the whole structure throughout a higher column, located over a cliff or a sea wall. Following

this

, the airflow reaches a turbine at the top of the column giving raise to a rotational movement, whose power is transformed into electrical energy.

Next

, as the wave slides away, a negative pressure is generated into the lower chamber.

Subsequently

, as the air flows back, it encounters the turbine again on the opposite side,

thus

keeping it rotating in the same direction and, despite the waves coming in a cyclical pattern, allowing the electricity production to go on as a continuous process.
