The diagram illustrates the generating of electricity using the hydropower From an overall point of view, manufacturing this renewable energy consists of several different stages, starting with the consumption of water from a reservoir and finishing with the generation of the hydroelectric. At the first stage of the process, water trapped in the Hydroelectric Dam's reservoir is released by running through an intake gate and makes its way across a narrow penstock. This raw water is eventually absorbed in a turbine below the dam, which later transforms them into the energy source in order to produce hydroelectricity In the subsequent steps, the water flow, now in the aforementioned turbine, is divided into two branches. One stream is pumped up by the turbine into a dynamo, the other is simultaneously discharged into the river. Concerning the former water line, it fills up the generator located inside a cabin called the powerhouse. In the final process, the movement of this water-fueled engine is converted into hydroelectricity. Then the resulting electricity is transmitted utilizing the long-distance power line.

There is a common belief that space-exploring operations are excessively lavish, especially in the context that there is a variety of different earthy issues that need to be taken into consideration. Hence, the advocates of this idea claim that it is imperative to cut down on the number of delving into the space. From my point of view, I found no justification to agree with this irrational statement since space expeditions may play an essential role in dealing with our planet's problems, namely environmental pollution and natural resource depletion. First and foremost, commissions to discover the universe may open up a solution to the problem of environmental pollution. It is worth pointing out that the degradation of the Earth's ecosystem is a consequence of overpopulation. By the way of exemplifying, the soaring of the global population is synonymous with the increasing demand for comestibles. Such necessity can be met through more intensive farming with the overuse of agrochemicals or through deforestation to create new farmlands, which in turn can have negative ecological outcomes. Then, by exploring outer space, mankind may have an opportunity to discover a habitable place to immigrate. This will consequently solve the matter of overpopulation and indirectly solves the interrelated environmental issues. In the second place, space exploration missions can also make a contribution to finding an answer to the shortage of natural resources. It does not seem unreasonable to suggest that the resources that are scarce on earth can be abundant on another planet. Then, the duty of space probing activities is to lay hands on such heavenly bodies, thereby creating a premise for space mining. For instance, celestial bodies in the solar system are potential sources for “rare earth” metals required for electronics, which consists of 17 elements, including lanthanum, neodymium, and yttrium, to mention but a few. From these aforementioned explanations, one could draw the conclusion that the argument for reducing the number of missions to explore space is preposterous as inquiring closely into space is the indirect solution to environmental pollution as it solves the overpopulation. Moreover, such missions are against natural resource depletion through mining other planets and asteroids in the solar system
