Read more about how you can change the way you live to reduce your footprint. | Australia's ecological footprint Australia has one of the world's largest ecological footprints per capita, requiring 6.25 global hectares per person. Global Warming Explained, In About A Minute : 13.7: Cosmos And Culture Jean-Pierre Clatot/AFP/Getty Images On a pleasant day in 2011, researchers roamed San Diego's public parks in search of volunteers to fill out anonymous surveys about global warming. In the end about 270 responses were collected from a mix of park visitors and nearby community college students. The researchers wanted to know how well the average American understands the basic processes responsible for global warming, and whether there's a relationship between this basic understanding and the belief that global warming is actually occurring. The results were sobering.

Climate change: Rising sea levels hit Maputo, Rotterdam When people talk about the impact of rising sea levels, they often think of small island states that risk being submerged if global warming continues unchecked. But it's not only those on low-lying islands who are in danger. Millions of people live by the sea - and are dependent on it for their livelihoods - and many of the world's largest cities are on the coast. By 2050 the number of people living in delta cities is set to increase by as much as 70%, experts suggest, vastly increasing the number of those at risk. To shed light the impact of rising sea levels, we are taking a close look at two very different cities, Rotterdam and Maputo , and their varying responses to the problem.
The Portrayal of Natural Environment in the Evolution of the Ecological Public Health Paradigm 2.1. Public Health and the Environment The environment has long been considered a determinant of health, but the environment conceived simply as the physical things surrounding people does not take into account the reciprocity between the environment and people. Public health has progressed from considerations of the physical environment as an undynamic external entity to a contemporary acceptance of the ecological paradigm. The ecological paradigm recognizes the relations not only between organisms but also between organisms and their physical surroundings. UCAR Center for Science Education The Nitrogen Cycle Nitrogen is an element that is found in living things like plants and animals, dead things like fallen leaves and dear animals, and non-living things like air and water. The nitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems. Nitrogen cycles slowly, stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way. Most of the nitrogen on Earth is in the atmosphere. Approximately 80% of the molecules in Earth’s atmosphere are made of two nitrogen atoms bonded together.
The system is failing, hack the system We live in an unsustainable world. Our climate is warming. Our food system is failing. Our clean water sources are drying up. But fear not, social entrepreneurs are here to the rescue! Desert Ecosystem The Oxford dictionary defines an ecosystem as "a biological community of interacting organisms and their physical environment." In other words, it's a network of plants, animals, and microbes, which work together as a unit in a particular area, and the abiotic factors of that area, such as location, climate, and soil. Though there is no definitive boundary of an ecosystem as such, following its nutrient cycle and energy flow can be helpful if you are to get well-versed with the concept. Energy Flow Through Ecosystems Summary:The objective of this lesson plan is to give students a basic understanding of how energy flows through an ecosystem by introducing them to the concepts of food chains and energy pyramids. Included in this lesson are two small group activities and a power point presentation. The power point presentation provides the students with fundamental knowledge about one way that organisms in an ecosystem interact and depend on one another. By using the power point lecture, the students are able to visualize food chains and energy pyramids.
The Australian desert – the outback of Australia Warning. Australian Stories may contain the names and images of Aboriginal and Torres Strait Islander people now deceased. Australian Stories also contain links to sites that may use images of Aboriginal and Islander people now deceased. Albert Tucker, Last days of Leichhardt, 1964, Harold Mertz Collection, University of Texas. Australia's desert landscapes, regarded as the ‘outback' of Australia, are a powerful symbol of place, and have inspired and helped define Australia's identity.

To hold back the desert. As of this writing, the Gobi Desert in northern China/southern Mongolia is about half a million square miles (1.3 million km2) in area. Yes, that's “as of this writing" — because the Gobi Desert is growing. Due to something called “desertification," about 1,400 square miles (3,600 km2) of China's otherwise arable land is turned into desert each year, as the Gobi creeps further and further south. To make matters worse, winds often pick up the sand, blowing it toward the densely populated areas in China, resulting in immense dust storms.
Climate Discovery Teacher's Guide Welcome to the Climate Discovery Teacher's Guide! This teacher's guide was produced by the National Center for Atmospheric Research as a companion to the Climate Discovery exhibit at our Boulder, Colorado laboratory. Each unit contains lessons appropriate for grades 5-9 on a variety of Earth system science topics that facilitate student learning about our planet's climate system. The lessons in each unit can be viewed using Adobe Acrobat Reader and may be reproduced for educational use.
Plant Behavior The Society for Plant Neurobiology was formed after the First International Symposium on Plant Neurobiology was held in Florence in 2005. This, and each of the subsequent symposia, were scientifically energizing and exciting, drawing a diverse array of participants. Plant Neurobiology describes a newly named, but also old and fascinating field in plant biology addressing the physiological basis of adaptive behavior in plants. Perhaps this field could be called "Sensory Biology in Plants" or something similar. However, these names don't quite cover topics like plant cytology and anatomy, adaptive plant behavior, signaling and communication in symbiosis and pathogenesis, or newly emerging topics like for instance plant immunity, plant memory and learning, plant-plant communication, as well as plant intelligence.
