Ein Gericht ist davon überzeugt, dass ein französischer Jogger starb, weil er giftige Gase von Algen einatmete – die wiederum sind eine Folge intensiver Landwirtschaft. Nun soll der Staat Verantwortun...

Cooking on gas?
Each year, about 40,000 people in the UK and Europe die prematurely from the long-term effects of nitrogen dioxide from gas cooking at home. It also impacts the health of those with chronic obstructive pulmonary disease.

3. H. japonica can withstand temps of -30 °C for up to 120 days. They essentially become 'dead', while their tissues fill up with glycerol & glucose & urea to prevent ice crystals from forming in their cells.
When weather warms, metabolism resumes. Ice zombies!

When used in fire retardant, ammonium phosphate can change the way the cellulose in plants reacts to heat. Ordinarily, plants exposed to a fire's heat begin to decompose and become fuel, but Phos-Chek acts as a coating, creating a barrier that consumes the heat energy.
What is the pink powder sprayed over the California wildfires?
The key ingredient in the fire retardant is ammonium phosphate, which is commonly found in fertilizer.

Some corals swap symbionts for more heat tolerant varieties. Others down regulate the amount of nitrogen they give to the symbionts
