The importance of organically grown food
By: David Nuttle
United Nations Food and Agriculture Organization (FAO) planners have indicated that organic production of foods will be the only means possible to provide enough food for growing world populations in future years. Factory farming, or non-organic food production, requires a high and sustained level of...
Why is groundwater important?
By: Imogen French
Life on Earth depends on water, especially fresh water, and without it we would not be here. Groundwater is an essential reservoir of fresh usable water that we can tap into when rain or surface water are not plentiful enough. A quarter of the world's...

In its native environment and native climate, an ash tree is a species in perfect balance within its ecosystem. As one of the first trees to spring back after a forest fire, ash trees are very tolerant of the high alkali content of post-fire ashes...

Groundwater is an important alternative to surface water. Sadly, this was not fully recognised until late in the 20th century when population pressures, variable rainfalls and increasing polluted water sources forced a search for alternatives. Groundwater, the forgotten, hidden resource attracted great scientific and geographical...

Growing food in a way that empowers people, rebuilds the environment and sequesters carbon are just some of the benefits of sustainable agriculture. This term, which used to describe the ethic of organic agriculture, combines cost effective approaches to agriculture with an environmental awareness when...
How forest fires help ecosystems and forests
By: Imogen French
Seeing the trail of devastation and destruction in Victoria, Australia this week (February 2009) it is hard to imagine that anything good can come of a forest fire. Wild fires like this are relatively common in many of the warmer, forested parts of the world:...
How forest fires help ecosystems and forests
By: Perry McCarney
Forest fires only help forest ecosystems that have evolved in areas prone to thunderstorms and therefore fire starting bolts of lightning. Forest ecosystems that have developed in other areas have had no reason to develop coping mechanisms for wildfires and can be utterly devastated by...
Why is groundwater important?
By: Perry McCarney
Groundwater is important to people for two very simple reasons. It is predominantly the water that we drink, and it is the water that nurtures and supports, either directly or indirectly, the food that we eat. Can we legitimately consider any natural resource, beside the...

A forest is best thought of as a constant dynamic balance. Old trees are brought down by windstorms, creating open spaces of partial sunlight where young seedlings can take root. Small, shade-tolerant seedlings grow into adult, sun-loving tree canopies. Leaf and branch litter falls on...
