On a day-to-day level, reduce contact and risk by following the ten tips outlined in The World Wildlife Fund's online pamphlet Reducing your risk: A guide to avoiding hormone-disrupting chemicals.
Write or call local, provincial and federal politicians, asking them to take action to reduce hormone- disrupting chemicals in our environment.
Planet Earth is part of an amazing, vast universe. On this planet are many different kinds of plants, animals, and people — all linked to one another in a complex web of life. All forms of life depend on one another and on Earth’s soil, air, and water. When one part is weak or unhealthy, all other parts are affected.
Earth provides everything we need. Every man-made thing started from something in nature. Plants and animals provide food and clothing. People build shelters using soil, clay, rock, trees, plants, and animal skins. People depend on air to breathe and on water for drinking, cleaning, growing plants, and more.
Problems on Earth
People have been wasting a lot of what they take from nature — plants, animals, water, metals, minerals, oil. Some of these precious resources nature can replace, but it often takes a long time. Others are irreplaceable. Many people use soil in ways that take away its life and allow it to be washed away where it clogs up rivers and lakes. Many industries release pollutants into air, water, and soil. While some people have much more than they need, many many others do not have enough food or clean water to stay healthy. Violence, such as war, destroys homes, health, and life.
What We Must Do
All people must join together to care for Earth and for one another. We have the scientific knowledge and means to clean up our air, water, and soil and to take care of everyone’s basic needs. The principles of the Earth Charter show us what to do.

Urban air pollution is an increasing problem in cities in the developing world. There is weak institutional capacity to address the issue in an integrated manner. There is usually little in the way of an organized knowledge base or development or application of analytical tools that may help support decision making in this regard. Most available tools are complex and data-intensive and there is a need for a new generation of simple interactive tools that can be used in cities in the developing world recognizing their information and institutional challenges. There is also a need to rapidly scale-up the use of analytical tools for not only the rapidly expanding megacities but also secondary cities that are developing significant urban air pollution problems. Modern information technology advances and increasing presence and networking in developing world cities offers a tremendous opportunity to develop simple tools to help city managers, regulators, the regulated, academia, citizen groups to develop a coordinated knowledge base and analytical approaches to develop a shared stakeholder vision for the issues and options in integrated air quality management for a city. This model was developed to illustrate an integrated analytical approach to air quality management to facilitate a learning event workshop on analytical tools on air quality management at the Better Air Quality Workshop in Agra in December, 2004. In discussions at the workshop and in many subsequent sessions, there was considerable excitement among participants in trying to develop and apply such simple, interactive and integrative tools for developing country cities. This feedback was also the inspiration to set up this list-serve to tap into a potentially large, interested global community to facilitate knowledge sharing of creative ideas, public-domain development and customized city applications of such integrated frameworks. Specifically, it would be useful to get your feedback on whether you know of similar simple, integrated tools in the public domain, potential for its use, and what you think could be future development directions.

Earth's water is always in movement, and the water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Since the water cycle is truly a "cycle," there is no beginning or end. Water can change states among liquid, vapor, and ice at various places in the water cycle, with these processes happening in the blink of an eye and over millions of years.
Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go in a hurry. The water in the apple you ate yesterday may have fallen as rain half-way around the world last year or could have been used 100 million years ago by Mama Dinosaur to give her baby a bath.
