Compost Week 2021 Question: What Percentage of food goes to waste? This question is appropriate because this is International Composting Week, May 2-8, 2021, with a theme: Grow, Eat…COMPOST…Repeat. Some foods don’t make it out of the fields. Potatoes, corn, and tomatoes that are too small, or too ugly, may be left behind in the fields. In some cased, the farmers announce that the edible, but ugly, food is available for gleaning – all you have to…
Earth Day 2021 Quiz (April 22, 2021) Test your knowledge of a few Earth related topics on Earth Day. Note that when you Google some of these topics, you can get rather wide ranges of answers.

World Water Day 2021 (in the rear-view mirror): Valuing Water. World Water Day (March 22, 2021) is past (www.WorldWaterDay.org)… By now you should have taken the Water Day Quiz at SustainZine.

The classroom, i.e., the future of sustainability was far behind. Later in 2010 Hall (2010) published…
IntellZine just wrote an article on how to Invest in the Future of Self-Driving Cars and EVs (https://www.intellzine.com/2020/12/invest-in-future-of-self-driving-cars.html). What’s not really covered is the Sustainability of EVs, self-driving cars etc. Internal combustion engines predominantly use fossil fuels but they can use renewable ethanol or biodiesel. Electric cars have the most promise because it is much easier to produce electricity from renewable sources like hydro, wind and solar. Plus, wind and solar have become the best…
VERGE 20 is on this week (starting October 26 2020). GreenBiz sponsor and coordinate this massive event. Anybody and any company that’s got anything to do with sustainability is here. Well, not exactly here since it is virtual this year… But you get the idea. Opening session was a wonderful start of the week. Even the singing was impressive. Really!
