Thirstwave

Researchers have coined a new term to describe extended periods of atmospheric thirst called Thirswaves.

About Thirstwave

  • A thirst wave has at least three consecutive days when daily evaporative demand is greater than its historical 90th percentile value for that period.
    • Evaporative demand is a measure of how thirsty the atmosphere is.
  • A combination of factors drives evaporative demand, including temperature, wind speed, humidity, and sunshine.
  • Studying these ‘thirstwaves’ can help farmers better manage their water resources and improve crop yields.

Recycled Plastic

A new study has raised serious concerns about the the health risks posed by recycled plastic.

About the study

  • A single recycled plastic pellet contains over 80 different chemicals.
    • These chemicals can leach into water and disrupt hormone systems and metabolism.

Recycled plastic

  • It involves collecting used plastic materials, breaking them down through various mechanical or chemical processes, and converting them into raw materials that can be used to manufacture new plastic products.
  • This reduces the need for virgin plastic production, conserves energy, and decreases pollution.
