health, food security, and access to safe water (UN WWAP 2013). This has resulted in 500 dead zones around the world, affecting 250,000km2, with the number doubling every ten years since the 1960s (UN 2013). These dead zones have neighbouring ecosystems that are part of a larger ‘‘still living’’ ecosystem, so it is feasible they could be revived should the causal factors be eliminated. This is where Community Dynamics plays a lead role in counteracting adverse change and enhancing the probability of the survival of its ecosystem.Each and every organism forms part of a community that also supports neighbouring communities, and Humanity has dominion over these relationships. We are able to preserve these relationships in two practical ways. The first is through mitigation of pollution (to alter neither community dynamics nor nutrient cycling) and the second is through preservation of natural water cycles (to sustain life). Every person forms part of Earth’s governing community and every person can reduce pollution. Equally important, every person can return natural water cycles to Nature. Simply put, with will and resourcing, Humanity can restore natural order and end destructive Climate Change.WASTEWATER KEY TO WATER CYCLEWastewater is a water-carried ‘’waste’’ typically containing 99.9 to 99.99 per cent water, so it comes as no surprise that more and more farmers across the globe are turning to reclaimed wastewater as an alternative source for crop irrigation. If this approach is universally managed it would stop marine pollution and benefit natural water cycles indefinitely. Notably, the World Health Organisation (WHO) has published practical guidelines for ‘‘sustainable’’ irrigation (for developing nations) with anticipated review (for developed nations).Photo Credit: Mikkel PitznerAbove: ALTERED OCEANS: Partially treated wastewater discharged to OceanLeft: WASTEWATER: contains energy-rich ‘Waste’
