What is a GMO? GMO stands for genetically modified organism. Breeders of plants and animals have long attempted to modify the genes of living things by selectively breeding the most successful organisms. This is a form of genetic modification. In most cases, however, GMO refers to changing the genes of an organism in a laboratory setting. For thousands of years, humans have used breeding methods to modify  organisms . Corn, cattle, and even dogs have been selectively bred over  generations  to have certain desired  traits . Within the last few decades, however, modern advances in  biotechnology  have allowed scientists to directly modify the DNA of microorganisms, crops, and animals. Conventional methods of modifying plants and animals— selective breeding  and  crossbreeding —can take a long time. Moreover, selective breeding and crossbreeding often produce mixed results, with unwanted traits appearing along...

 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...

  Attention Deficit Hyperactivity Disorder (ADHD) ADHD is a condition that affects people’s behaviour. People with ADHD can seem restless, impulsive and have problems concentrating. Studies show that ADHD may affect certain areas of the brain that allow us to solve problems, plan ahead, understand others' actions, and control our impulses. Most cases are diagnosed in childhood, but it’s possible to be diagnosed as an adult. ADHD can’t develop for the first time in adults, but you may have had it as a child and not been diagnosed. What are the symptoms of ADHD? The symptoms of ADHD fall into two groups: inattentiveness, and hyperactivity and impulsiveness. You may have difficulties that fall into one or both categories. Symptoms of ADHD may present themselves differently. For example, boys with ADHD may be more disruptive in the classroom than girls. Adults are less likely to show hyperactivity. ADHD in children and teenagers The main symptoms of inattentiveness include: a short att...

  Effect of Climate Change on Marine ecosystem The world’s oceans cover approximately 70 percent of the Earth’s surface, indicating their importance to the global environment. In addition to having a large influence on global heat transport and precipitation, the oceans are comprised of diverse habitats that support a wealth of marine wildlife. They also provide humans with a wide variety of goods and services including foods, recreational opportunities, and transportation corridors.  Based upon current scientific evidence, emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create new challenges for coastal and marine ecosystems that are already stressed from human development, land-use change, environmental pollution, and over-fishing. Climate change is likely to alter patterns of wind and water circulation in the ocean environment. Such changes may influence the vertic...

Forests and Climate Change Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”. The greenhouse effect makes the earth warmer, just as a greenhouse is warmer than its surroundings. Carbon dioxide is the main cause of human-induced climate change. It stays in the atmosphere for a very long time. Other greenhouse gases, such as nitrous oxide, stay in the atmosphere for a long time. Other substances only produce short-term effects. Billions of tons of CO2 are released into the atmosphere every year as a result of coal, oil, and gas production. Climate change is a direct cause of soil degradation, which limits the amount of ...

Radicalization of Youth From socializing and entertainment to homework, the Internet is an essential part of life for young people today, opening vast new opportunities for connecting and learning. At the same time, the Internet provides violent extremists with powerful tools to propagate hatred and violence and to identify and groom potential recruits, creating global online communities that promote radicalization. Radicalization refers to the phenomenon by which individuals or group of individuals exhibit radical political, social or religious ideology and aspirations that oppose and reject contemporary ideas of mainstream society of the nation. Simply Radicalization is the process by which an individual or group comes to adopt increasingly radical views in opposition to a political, social, or religious status quo.   Radicalization can be both violent and non violent however in general instruction radicalization is more focused on violent extremists ideologies and activiti...
