Walking on two legs is an evolutionary leap that led humans to conquer the world. But, why humans are walking on two legs? It’s still unclear. Now, according to a new study published on the University of Chicago’s Journal of Geology, the reason might be exploding stars a few million years ago.
Many of us think that rapid environmental change is a quintessentially modern crisis. Today, temperatures are soaring, topsoil is washing away, phosphorous is being diluted, forests are retreating, pesticides are sterilising farmland, fertilisers are choking waterways, and biodiversity is plummeting under the onslaught of overpopulated, industrialised societies. Some of these changes are indeed truly new. But many others have deep roots and distant echoes in the early modern period, the years between around 1400 and 1800 when much of the world began to assume its present form. Recently, scientists, geographers, historians, and archaeologists have combined expertise and evidence to reveal just how profound early modern environmental transformations really were.
New and developing technologies like artificial intelligence, robotics, and virtual and augmented reality (among others) are really cool. We love to see how robots can differentiate between objects, artificial intelligence can assist psychologists, and virtual reality can allow us to enter new worlds. But how can today’s youth reap the benefits of these amazing technologies in their everyday lives to prepare them for their future?
The world has been urbanizing rapidly in recent decades. In 1950, only 30 percent of the world’s population lived in urban areas, a proportion that grew to 55 percent by 2018. The global urbanization rate masks important differences in urbanization levels across geographic regions.
Northern America is the most urbanized region, with 82 percent of its population residing in urban areas, whereas Asia is approximately 50 percent urban, and Africa remains mostly rural with 43 percent of its population living in urban areas in 2018 (United Nations, 2018).
Hong Kong, New York, London, Tokyo, and Paris – all of these cities are quite unique yet same in so many regards. They represent technological, social and infrastructural hubs of what is commonly referred to as a modern human society. No matter what background, professional experience or connections you may or may not have, chances are that something new waits in each of these cities – and that is a problem.
Increasing environmental sustainability has become an important topic both on the minds of many individuals and in the media. This is for good reason – recently, studies have starkly illuminated the impact of climate change and the role humans play in increasing global temperatures. With sobering consequences such as drought and more severe weather patterns, an increased number of people have started to consider how they can become more sustainable. In this global shift, many cities are moving to become more sustainable and decrease negative impacts on the environment. Although the level of involvement varies by city and country, an evolution is occurring as cities implement improved infrastructure and policies to become more sustainable.
To champion science is to celebrate life. It is to apply the lessons of the laboratory to real-life circumstances. It is to address matters of life and death. It is to stay calm amidst chaos and confusion. It is to recognize the urgency of the need to act-in an emergency-when there is no time to wait for first responders to arrive on the scene.
This is perhaps one of the most powerful and thought-provoking quotes I have ever come across. The environment is really something that we all have in common, and we cannot afford to lose it at any cost.
One of the biggest global health crises we face today impacts more than a billion people. It’s not HIV or heart disease. Malaria or mental health. It’s vision impairment. More than 253 million people are visually impaired and there are 1.1 billion people with near-vision impairment according to a paper published by the Vision Loss Expert Group in the Lancet. But a simple pair of eyeglasses can change the lives of these people dramatically.
