    Light Pollution Is One of the World’s Biggest Buzzkills…Here’s Why

    Have you ever come home from a long day to find your front door swarmed by flying insects? Or more accurately, your front door’s light? Turns out, that’s more than a minor inconvenience. Light pollution is contributing to worldwide insect decline and that’s actually a huge problem. Insects may seem pesky. They bite and sting us, flutter and scuttle into our houses, swarm around our faces and eat our crops. But actually, of all the insects in the world, only 1% of them are pests responsible for any real damage! And almost all insects play really important roles in our world. For instance, many are pollinators, so they keep ecosystems…

    Sustainability? Answering Google’s 4 Most Search Questions

    Hi Alex here. Nice to see you again. I am excited today because, we are answering the 4 most searched questions about sustainability on Google. This is the TOP 4 questions people have when they search sustainability on Google: What is a simple definition of sustainability? What are the 3 pillars of sustainability? Why is sustainability so important? and How can we achieve sustainability? Ok, let’s answer the first question: Sustainability is the capacity of our human society to continue indefinitely within Earth’s natural cycles. Then a development that leads toward full sustainability. It makes sense so far, right!? What are these natural cycles? In 1989, after many drafts, a…

    “Investigating Geochemical Processes of Fluid-rock Interactions” – a public oral defense

    As a geochemist, I often get this question “what is geochemistry?”. Geochemistry, essentially, is using chemistry to understand geological phenomena. And this talk will explore the fluid-rock interactions from a geochemical perspective. Understanding fluid-rock interaction is essential for subsurface energy applications such as fossil fuel development, nuclear waste disposal, CO2 sequestration, and geothermal energy extraction. All these activities involve geochemical processes. My PhD research includes two different approaches: computational and experimental. Here I would like to share two stories to highlight each. The first story is about using computational techniques to study the interactions between oil and shale. The second story is about the experiments targeting the interaction between aqueous…

    The Natural Environment of Tudor London

    I could have chosen any number of individuals to act as a guide through the Tudor London. but we know that Sir Thomas was an intelligent man with an eye for curiosity and an understanding of the broad sweep of history too – and that’s a sound basis I think for a companionable walk. I’m not a historian, so I should own up to that. I’m an environmental scientist, so some of the history, I’ve had – I’ve had to get to grips with myself. Strictly speaking the medieval period ended and the Tudor period began on the 22nd of August 1485, when Henry Tudor defeated Richard the third at…

    Forest schools: A growing alternative for parents wanting less screen time for kids | ABC News

    I think it’s a huge part of my role as a forest school leader is to support families to understand how diverse and fabulous this environment is. People are coming to me because they want to reconnect with nature, that’s a really innate part of who they feel that they want to be or they want their children to be. I think there’s all this research that shows that technology can be harmful for children and I think that people want to come back to basics and connect with what’s around them. We love it, it gives the kids a chance to play outside on actual trees and rocks and…

    Noise Pollution Is a Bigger Deal Than You’d Think

    [♪ INTRO] In 2001, shortly after the September 11th attacks in the United States, something strange happened to a group of whales near eastern Canada: They relaxed. Specifically, researchers found lower levels of stress-related hormones in their poop, which is apparently how you measure these things. And this didn’t seem to be a coincidence. In fact, after more observations, there seemed to be an obvious cause: Right after 9/11, the waters off the east coast of North America were quiet. There were fewer ships than normal, and the whales appeared to let out a collective sigh of relief. At least, figuratively. This study was pretty famous when it finally came…

    What detoxifies a negative work environment? | Simon Sinek

    When we talk about a trusting team or trusting partners I think very often we forget that trust is not an instruction. Trust is a feeling. You cannot tell someone to trust you. No leader can just tell their company trust me. It doesn’t work that way. Trust is a feeling. It’s a biological feeling that comes from the environment we’re in. When we feel safe in our own environment, when we feel that our leaders care about us as human beings and want to see us grow and build our confidence in our skills, when we feel safe in our own companies, trust emerges. It’s what happens. When we…

    6 Microbes Saving the Environment

    Thanks to Brilliant for supporting this episode of SciShow. Go to Brilliant.org/SciShow to learn how you can take your STEM skills to the next level! [♪ INTRO] Ever since humans found out germs were a thing, we’ve had a vendetta against microbes. The idea that death can be doled out by stuff we can’t even see is pretty unsettling. So we invented antibacterial soap and antibiotics and antifungals, and we went a little bit overboard in the end with the anti-everythings. And as a result, we’ve often ignored the existence of good microbes. With the exception of the ones that give us cheese and yogurt and beer and bread, of…

    Teachers explain benefits of environmental education | Maryland, US | World Future Council

    The teachers are integrating environmental education into their English language, arts classes, the social studies classes, math and science. So, the students are planting trees, planting native plants, they are helping to create outdoor classrooms, recycling, waste management. There are in elementary schools energy monitors who are making sure that when the class leaves the classroom the lights are turned off. I think what’s really great about it is the fact that the kids get so involved with things, you know, they’ve never been involved with before. And you just see that spark, you know, inside of them, wanting to know more. You see them engaging and asking questions and…
