Carbohydrates and Climate Change

Our Thursday green news brings you the latest on green architecture, climate change, energy and communities:climate change, trees and climate change

  • Carbohydrates and climate change: According to a new study recently published in the journal Nature Climate Change, an international team of scientists have discovered a type of carbohydrate that can help tropical trees to survive during drought conditions. The researchers tested 1,400 saplings made of 10 different tropical tree species, investigating whether restricting the trees’ ability to generate non-structural carbohydrates (NSC), that seam to play a part in tree’s hydration, would lead to them  dying more quickly. Based on the results, scientists can now start predicting which forests might be particularly vulnerable, and the extent of their vulnerability, in the face of rising temperature due to climate change. As the study authors explain: “We have various models for different levels, so scientists in theory at least could begin to estimate how much of our forests are under threat, and how by diversifying the species, we could help ensure that our forests are more hardy when those conditions do eventually arrive.”
  • Whole Foods and sustainable flowers:  As demand for eco-friendly flowers grows among consumers, some companies such as Whole Foods are reacting with their supply of fair trade flowers. As Carol Medieros, associate global produce coordinator for Whole Foods Market explains: “Ideally, all the flowers for sale in an upscale natural foods store would be organic, however the global supply is lacking. Whenever we can find a high-quality organic flower that our customers are asking for, we do support it. But because the supply is very small, we’ve looked to have sustainable flowers in other ways. For example, we look into local flowers or those that meet the requirements of the company’s Whole Trade Guarantee.” Whole Foods also sources flowers from developing countries as part of their Whole Trade Guarantee program, which promises to ethically source flowers from developing nations. The program should ensure that a fair price is paid to flower producers and that farm laborers work in safe and healthy working conditions; and that the product is grown with environmentally friendly practices.
