 Biotechnological Ethics Biotechnology can be defined as the technical manipulation of living organisms or parts of those organisms to provide products and services to satisfy human desires. If it is defined in this broad way, one can see that biotechnology has been employed throughout human history. The history of biotechnology can be divided into three periods: ancient, modern, and contemporary. Ancient biotechnology began more than 10,000 years ago with the emergence of agriculture in ancient Mesopotamia. Modern biotechnology began in the nineteenth century with the development of industrial microbiology. Contemporary biotechnology began in the 1970s with new techniques for genetic engineering . In each period one can see the power humans have acquired to manipulate nature. But one also can see the natural limits of this power, which is constrained by the natural potentialities available in wild plants and animals and the natural complexities of behavioral traits in the living w...

  Global Warming, Climate changes and Its Impacts In the last five decades, human activities have resulted in the release of increasing quantities of carbon dioxide and other greenhouse gases, thus contributing to global climate change by additional heating of the atmosphere. The world has warmed up by approximately 0.85 °C. In particular, the last decade has been the warmest since 1850, and the frequency and intensity of natural disasters (such as earthquakes, devastating storms, forest fires, prolonged heat waves, droughts, and floods) have increased manifold. Between 1998 and 2017, climate-related and geophysical disasters killed 1.3 million people and left a further 4.4 billion injured, homeless, displaced, or in need of emergency assistance. Climate change scenarios include a change in the spread of infectious diseases with warming and changes in outbreaks associated with extreme weather events after floods or as a result of water heating. Furthermore, warmer climates pro...
