Crypto mining, the arcane process by which cryptocurrencies are generated, is incredibly energy-intensive.  As of this past summer, global electricity usage for the activity is as much as 240 billion kilowatt-hours per year, which is more than many entire countries use (for example Australia and Argentina.)  Crypto mining consumes as much electricity as all the […]

Deforestation is the purposeful clearing of forested land. Forests are cut down to make space for animal grazing, agriculture, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world and continues to do so today.  Deforestation is the second largest contributor to global greenhouse gas emissions, trailing only […]

People have been cultivating rice for more than 9,000 years.  Cultivated rice is an annual crop which is often extended to two crops a year by a process called ratooning, which is cutting back annual rice to obtain a second, weaker harvest.

India is the country with the second largest population in the world – over 1.4 billion people – second only to China – and will undoubtedly pass China soon based on population trends in the two countries.   India is the third largest emitter of carbon dioxide, after China and the U.S.  With its rapidly growing […]

People have intentionally or accidentally introduced numerous invasive species to habitats around the world.  At the same time, the planet’s wildlife is in a steep decline.  A recent study estimated that the populations of over 5,000 vertebrate species have declined by an average of nearly 70% since 1970.  A United Nations report warns that human […]

The world’s economies including its energy markets have been in turmoil in recent times but despite the chaotic conditions, the shift to clean energy is gaining momentum.  This year, for the first time, the world is investing more in wind and solar power than in oil and gas drilling.  Investments in renewables are expected to […]

Plastic waste has been accumulating in the world’s oceans in greater and greater quantities and much of it is in the form of microplastic particles.  Many kinds of whales – the largest creatures on Earth – feed by gulping up mouthfuls of krill and other tiny creatures and then straining the seawater through bristly filter […]
