Transgender fish rise in the Potomac

Fish in dragThe Potomac River, which flows through Washington, DC, has nurtured trade, cultures, migration, and living resources for more than 10,000 years.

Captain John Smith visited the Potomac in 1608. He found fish “lying so thicke with their heads above water, (that) for want of nets, we attempted to catch them with a frying pan.”

It’s a different story today. Some species of male fish in the Potomac River are developing female sexual traits at a frequency higher than scientists have seen before, raising concerns about pollutants in a waterway that provides drinking water for millions of people.

Water Wars

Water wars info

Of all the water on earth, only 2.5% is fresh, and less than 0.007% is readily available to people through rivers, lakes, and streams.

As worldwide populations surge, temperatures rise, climates changes, and diseases spread, clean water will become ever more essential (and ever more rate).

In 2000, United Nations Secretary-General Kofi Annan warned that national rivalries over water could harbour “the seeds of violent conflict.”

Are Water Wars coming? This infographic, below, from the International Networks Archive puts it all in perspective.
