Explanation:
Fracking, also known as hydraulic fracturing is a drilling method used in the oil and gas industry of most countries. It is the process whereby natural gas and petroleum is extracted from deep down the Earth. A crack is made in the rock layers, followed by the injection of a liquid called fracking liquid, which is usually water, at a very high pressure.
The process of fracking has serious environmental side effects e.g. release of harmful gases, noise pollution, water contamination etc. and hence, when choosing a fracking site, environment's sustainability and safety of people should be taken into account. This is why a fracking site cannot be designed in a residential city or around a neighborhood. The site should rather be designed in a location where it would pose a minimal environmental threat to the people e.g flat, vacant plot in the outskirts of the city
Our circulatory system is a complex network of blood vessels that carry blood from the heart to all parts of the body and back to the heart.
In doing so, the circulatory system provides all cells with the oxygen and nutrients they need, and removes waste and toxins. In addition to normalizing the temperature and pH of the body, the blood supply helps to heal any injury or injury.
Cardiovascular disease is the leading cause of death in the world according to WHO. So it's important to take care of our circulatory system, arteries and bloodstream to prevent diseases such as stroke, high blood pressure, arrhythmia or phlebitis.
Poor arterial circulation can be the result of narrowing or blockage of the arteries. In the Western world, the main cause of such deficiency is the accumulation of cholesterol within the arterial walls, which impairs the movement of blood flow.
If you have poor venous circulation, your veins will have trouble returning blood from the bottom of your body, especially the legs, to your heart. The blood will then tend to accumulate in your veins, which can lead to the formation of varicose veins.
