It's fantastic.00:00:17:18KATHY MCLEISH:Floodwaters pouring in from Central Queensland and torrential inland rain have filled waterholes and wetlands. Some of the animals and plants which have come to life are rarely seen in the desert. Scientists are mounting expeditions to try and learn what they can before the water and the new animals and plants disappear again, as they must.00:00:45:08CAMEL:(Bleats and moans)00:00:51:03ANDREW HARPER:This guy's pretty vocal in the morning.
That's just his normal 'good morning' noise.00:00:55:01KATHY MCLEISH:Andrew Harper is loading up for a trek on a conservation property called Ethabuka, which covers 213,000 hectares of the desert.00:01:04:16ANDREW HARPER:Doing it for 15 years now.

Just get them to plant and grow their own, like these students have, and they can't get enough of them. Now, this fish emulsion is full of nitrogen and, of course, that fuels all this wonderful leafy growth. And when things are growing quickly it's good to apply this about once a month. Look at that, you can see they're growing already. Restoring a native creek habitat. 00:00:00:00Two schoolgirls are seated in chairs in a garden. Text on screen - 'I made this!

Online exhibits The world's biomes Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (Campbell 1996). The importance of biomes cannot be overestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all.
For further information, please consult the references page. Here we group biomes into six major types: Conservation and preservation of biomes Because we share the world with many other species of plants and animals, we must consider the consequences of our actions. Forests are important as they are home to the most diverse biotic communties in the world. Logging has depleted many old-growth temperate forests. Freshwater biomes have suffered mainly from pollution. 3.1 Factors affecting climate — Environmental Change Network. There are many different factors that affect climate around the world. It is the varying influence of these factors that lead to different parts of the Earth experiencing differing climates.
The most important natural factors are: It is now widely accepted that human activity is also affecting climate, and that the impact is not the same everywhere. For example, changes appear to be happening faster near the poles than in many other places. Distance from the sea (Continentality) The sea affects the climate of a place. Ocean currents Ocean currents can increase or reduce temperatures. The Gulf Stream is a warm ocean current in the North Atlantic flowing from the Gulf of Mexico, northeast along the U.S coast, and from there to the British Isles. The Gulf of Mexico has higher air temperatures than Britain as it is closer to the equator. The Gulf Stream keeps the west coast of Europe free from ice in the winter and, in the summer, warmer than other places of a similar latitude. El Niño. The Concept of the Ecosystem. "I bequeathe myself to the dirt, to grow from the grass I love;If you want me again, look for me under your boot-soles.
"- Walt Whitman In this lesson, we will learn answers to the following questions: What is an ecosystem, and how can we study one? Is the earth an open or closed system with respect to energy and elements? Introduction - What is an Ecosystem? An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components. Studies of individuals are concerned mostly about physiology, reproduction, development or behavior, and studies of populations usually focus on the habitat and resource needs of individual species, their group behaviors, population growth, and what limits their abundance or causes extinction.
Figure 1. 1. 2. Mission: Biomes. Documentary about regenerating large-scale damaged ecosystems | EcoLife Global. Meet John D. Liu, the environmental film maker who says "it is possible to regenerate large-scale damaged ecosystems. " The documentary film looks at restoration projects in China, Africa, South America and the Middle East, who aim to rejuvenate eroded landscapes. Permaculture teacher Geoff Lawton, who stars in the film states: "The world gets more and more complicated all the time but the solution to fix the major problems of the worlds ecosystems remains reasonably simple. We have to go ahead on a major scale now.
Spreading the message of change The key message here is that change is possible. In the final moments of the film, Lawton says "There's not too many people in the world in my view, it's just that most people don't realise they are acting in a very negative way in relation to the environment.
