It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end. Despite this few scientists, policymakers, or even environmentalists are willing to publicly connect incredible population growth to worsening climate change, biodiversity loss, resource scarcity, or the global environmental crisis in general.

It has been well documented that one negative of air travel – besides the food – is the emission of CO2 from jet engines. But what about contrails?
Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing’s journal Environmental Research Letters.
According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2.

It seems as more and more of the fish available to us in the supermarket and in restaurants is farmed. Is this good or bad? Probably a bit of both. Raising fish in fish farms doesn't impact the wild fish to any great extent, but fish farms must be well situated, and well run to prevent problems. They are not natural ecosystems!
Aquaculture has become a booming industry in Chile, with salmon and other fish farmed in floating enclosures along the South Pacific coast. But as farmers densely pack these pens to meet demand, diseases can easily pass between fish — for example, an outbreak of infectious salmon anemia that emerged in 2007 caused the deaths of more than a million fish and threatened to cripple the industry. And unsustainable aquaculture methods can have a wider impact, spreading disease to the world’s already vulnerable ocean fisheries and contaminating the environment.

A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists.
