    How China Is Dealing With Its Water Crisis

    Recently I traveled to Southeast Yunnan in China to see the spectacular Yuan Yang rice terraces, flooded and ready for spring planting. Rice is a very water-hungry crop and China is the world’s largest producer of rice and grain. Yet China is facing a perilous water crisis.

  • What You Can Do to Protect Biodiversity

    What You Can Do to Protect Biodiversity

    What can we as individuals do to help slow the loss of biodiversity? Since consumption of resources is a root cause of biodiversity loss, we can consume less and be more mindful about what we consume.

  • From Wastewater to Drinking Water

    From Wastewater to Drinking Water

    Across the globe, 2 out of 10 people do not have access to safe drinking water, and in the U.S., many states face water shortages and droughts. As the global population continues to grow and climate change results in more water crises, where will we find enough water to meet our needs?

    Biomimicry: Learning From Nature’s Genius

    Biomimicry is the science of studying and emulating nature’s solutions to the problems that human beings are trying to solve. Over the 3.8 billion years that life has existed on Earth, nature, through evolution, has come up with sustainable and robust solutions that work and that endure.

  • Ethanol’s Impacts on Our Water Resources

    Ethanol’s Impacts on Our Water Resources

    Ninety-five percent of ethanol in the U.S. comes from corn, but corn-based ethanol is controversial because of the amount of land required to grow the crops, and because of its effect on food prices and water resources.

  • Why is Your Nitrogen Footprint Important?

    Why is Your Nitrogen Footprint Important?

    While most people today are aware of the importance of reducing their carbon footprint, far fewer understand the harmful effects of nitrogen pollution. Yet many scientists believe that man’s disruption of the natural nitrogen cycle is a potential global tipping point and a serious threat to biodiversity.

    The Fog Collectors: Harvesting Water From Thin Air

    Today nearly two people in ten have no source of safe drinking water according to the U.N. But in some desert areas, where there is very little rain, fog and dew are abundant sources of humidity that are being harvested to produce fresh water.

  • Giant Jellyfish Swarms – Are Humans the Cause?

    Giant Jellyfish Swarms – Are Humans the Cause?

    Many scientists believe that jellyfish, particularly jellyfish swarms or blooms, are on the increase worldwide, turning up in regions where they never existed before. Research shows shows that many human activities are strongly correlated to jellyfish blooms.

    Seawater Greenhouses Produce Tomatoes in the Desert

    With the global population increasing by 80 million each year, a third of the planet will likely face water shortages by 2025. This looming water crisis is inextricably linked to food production…
