The explore Team travels to India, China, Costa Rica, and the Arctic to see the impact of humanity on the planet's most important resource: water.

Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

A solar water heater can save around $450 in a year and can keep tons of CO2 emissions out of the air. If that is multiplied by 80 millions houses in the U.S., just imagine how clean we can keep our environment.

Wastewater treatment is the process of converting wastewater into an effluent that can be discharged back into the environment with a legal standard, which is certified generally less impact on the water cycle; the effluent is directly reused for other purposes. At the same time, the Valuable components from wastewater could be enriched as resource recovering.

The UK's seas could provide enough extra wind energy to power the equivalent of 19m homes, according to an assessment by the government. The government's strategic environmental assessment (Sea) confirmed projections that an extra 25GW of electricity generation capacity could be accommodated in UK waters. This would be in addition to the 8GW of wind power already built or planned offshore, bringing the potential total electricity capacity of offshore wind to 33GW - enough to power every household in the UK.

Jamestown High School in Virginia is asking classes to track their water usages for one week.

Britain is trying to water down tough new European legislation to boost the uptake of renewable energy, despite a pledge by Gordon Brown last month to launch a "green revolution" based on clean technology. Documents obtained by the Guardian show the UK wants to block attempts to give renewable electricity sources such as wind farms priority access to the national grid. The European official who drafted the legislation accused Britain of "obstructing" EU efforts on renewables and said UK officials wanted to protect traditional energy suppliers and their coal, gas and nuclear power stations.

The challenges our society faces with depleted energy resources, water shortages, soaring food costs all point to environmental solutions.

As of the end of 2011, China's seawater desalination capacity reached 660 kilotons per day, and the figure, as scheduled, will hit 2.2-2.6 million tons per day in 2015. In recent years, world's renowned corporations in the water treatment engineering field have sped up their inrush to Chinese seawater desalination market. Veolia Water entered Chinese water treatment market early in 1997, now with over 15 projects in China, mainly in Tianjin, Shanghai, Beijing, Shandong, Shaanxi, etc.

Wind supplied more of Britain's electricity that water for the first time last year, while power generators preferred gas to coal and nuclear output continued to decline, according to new government data. Five percent of Britain's electricity came from renewable sources in 2007, up from 4.6 percent in 2006, as more wind farms started feeding clean electricity into the network, helping cut the country's carbon emissions.

The Scottish Government has created one of the biggest international innovation prizes in history - a £10 million challenge for advances in wave and tidal energy. At a ceremony this week in historic Edinburgh Castle, details of the 'Saltire Prize' were revealed to leading scientists, environmentalists and potential entrants after being finalised by a panel of international experts who comprise the prize Challenge Committee. Dr Anne Glover, Scotland's Chief Scientific Adviser and Chair of the Challenge Committee, said the Saltire Prize will be awarded to the team that can demonstrate in Scottish waters a commercially viable wave or tidal energy technology that achieves a minimum electrical output of 100GWh over a continuous two year period using only the power of the sea and is judged to be the best overall technology after consideration of cost, environmental sustainability and safety.

Stories about moms turned activists resonate with me. Having a child with persistent asthma, after all, motivated me to start advocating for cleaner air and lower emissions through websites like this one. There is nothing quite like the mothering instinct kicked into overdrive and funneled into the effort to protect and preserve the land, air, and water for our children. On a less serious note, the chaos of early parenthood is possibly the best training available for battling environmental damage.

California issues plan to slash greenhouse gas emissions Over the next 12 years, new regulations would seek to turn the climate change clock back to 1990 levels. More efficient electricity use, less traffic and cleaner cars are goals.
