It’s not easy to keep track of the complex ways in which our everyday choices have an impact on a global scale. But as the world’s population surpasses 7 billion, each of our actions—positive or negative—gets multiplied.

World leaders gathering at the UN in New York next weekend must pledge to make a revolutionary effort if they are serious about meeting the 17 ambitious anti-poverty targets for 2030 that they are due to sign, according to Britain’s leading development thinktank.

Humans are "eating away at our own life support systems" at a rate unseen in the past 10,000 years by degrading land and freshwater systems, emitting greenhouse gases and releasing vast amounts of agricultural chemicals into the environment, new research has found.

As the demand for freshwater and energy increases in San Diego County and Northern Baja, the fresh water supply continues to shrink while energy generation remains heavily dependent on fossil fuels. Due to these opposing trends in supply and demand, it becomes increasingly imperative to identify solutions that move these communities to their preferred state in which they are largely reliant on renewable energy and use water sustainably. Large-scale energy solutions include wind power, one of the must abundant sources of energy in these regions.

The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday.

There are several different directions that our planet can take to address the ever growing need for water and energy. This will involve integrating technologies of a large and small scale into our grid and into our homes as well. There are two main technologies in which to address large scale water sustainability: desalination and ‘pure water’ recycling. As the California dries out, it is increasingly important to adopt proven strategies to maintain the current standard of living.
