Though meteorology and oceanology have made a great progress for the last decades, predicting hurricanes and their intensity is still tough. Climatologists warn that climate change makes hurricanes even tougher to predict with every year. Hurricane Harvey was close to confirming these hypotheses. Even with a lot of warning, the effects were devastating. The mechanism is simple – warming water gives more power to the storm as the planet heats up. Climate change does not directly cause the hurricanes but it can actually turn quite a small tropical storm in a natural disaster. The devastation caused by

Heading towards 10 billion point expected in 2050, ever-increasing world population will likely cause multiple crises. A shortage of natural resources and an excess of waste are capable to dump humanity in a steady recession directly caused by overpopulation. The United Nations reported that most of the global population increase is attributed to several countries only. Among them, China and India remain the most populous with Nigeria approaching them. Congo, Pakistan, Ethiopia, Tanzania, Uganda, and Indonesia are on the top of the list as well. Curbing overpopulation is directly associated with the implementation of development goals. Putting

Despite major concerns about plastic, paper waste is one of the major sources of pollution globally. Paper production is the third most energy-intensive type of manufacturing in the world. Besides, it is responsible for the release of toxic substances such as chlorine, mercury, lead, and phosphorus into the atmosphere. It also turns out that Americans are the biggest paper users in the world. Recycling is energy-consuming as well, and cutting paper consumption is the only effective way to reduce pollution. It is especially easy to reduce paper consumption in the digital age. At school or work, we

Today teaching techniques have expanded beyond the traditional teacher-students mode. There are plenty of patterns of an innovatory teaching. They involve more teachers and machines to make traditional learning more effective. Take a team teaching, for example. A team of teachers works with a team of students. Each teacher may specialize in different subjects, which expands the overall specialization of the teaching group. A clear advantage of team teaching is a broad expertise of teachers. It is often impossible for one teacher to specialize in numerous aspects of the subject. Distance education is a new and very

According to the Center for Disease Control and Prevention, Americans consume 75% of the world’s prescription drugs. Patients do not think that they consume too much pharmaceuticals on the daily basis unless they look at the total price of the prescription. What people need is a quick and easy relief – exactly the thing prescription drugs can give. Nevertheless, big pharmaceutical companies earn on patients, and so do doctors. Speculations about the deliberate overuse of prescription drugs make people believe that doctors turn their patients into drug addicts on purpose. On the one hand, the theory mentioned
