Agricultural weed killer prosulfocarb is now killing the river Meuse (Belgium, Netherlands). Drinking water intake has stopped. Again a signal that it’s time to rethink the way we do agriculture. https://t.co/sf2w3w2EPl

With 70-75% of all people being vegetarian, the states of Rajasthan, Punjab and Haryana in India are the world’s leading examples. Reducing our environmental footprint is possible!

[Mrinal Pande @MrinalPande1]

For those who were not pleased w the map image based on GOI census figures but wanted precise figures on prevalence of vegetarianism and non vegetarianism in India, State wise.

The Colorado River is dammed at the US-Mexico border, and on the other side the river channel is empty. Locals in Mexico are now battling to bring it back to life. This is part of a year-long series from @guardian called Our Unequal Earth: https://t.co/VJQi2XBiHH

News!? Carlsberg commits to reduce brewery water use from 2.9 to 1.4 litre per litre of beer. But they need ~300 litre of water per litre beer to grow barley etc. They will reduce the water footprint of their beer by 0.5%.. Waiting for the real commitment! https://t.co/85G6t0HDR5

@rhaar000 @carlsberg @CarlsbergGroup @WWFWaterRisk @WorldBankWater @UN_Water @UNESCOWWAP @ADBWater @GWFWater @H2O_stewards @USWaterAlliance En het goede nieuws voor de Nederlandse boer: 300 ltr water / ltr bier is het mondiale gemiddelde. In NL (met Nederlandse gerst) is het ~90 ltr water / ltr bier. Minder kan haast niet, alleen die watervervuiling kan nog minder (stikstof....)

@rhaar000 @carlsberg @CarlsbergGroup @WWFWaterRisk @WorldBankWater @UN_Water @UNESCOWWAP @ADBWater @GWFWater @H2O_stewards @USWaterAlliance 300 liter is som van waterverbruik (regen + irrigatiewater) & watervervuiling om gerst te maken voor 1 liter bier. Er is geen reden schamper te doen over efficient regenwatergebruik. Hoe meer bier per druppel water hoe beter. Minder water voor bier = meer water voor andere zaken.

Berkeley Earth Update for September 2019

+0.83 ± 0.06 C above the 1951-1980 average

Or equivalently, +1.21 ± 0.07 C above the 1850-1900 average

Warmest September since instrumental measurements began in 1850.

The most effective way to reduce our water footprint is to switch to a plant-based diet https://t.co/Nd9ZXPfRWL

Also better for health, animal welfare, nature conservation, biodiversity & climate! No need to wait.

Increasing numbers of scientists concerned about climate change raise their voice. Support from university boards is so welcome! Thanks @UTwente https://t.co/JB05RC6oV2

Conclusie #Stikstofdebat:
Het kabinet moddert door; boeren en natuur blijven in onzekerheid. Terwijl wetenschappers en juristen waarschuwen dat stikstofplannen nog ver onder de maat zijn. Krimp veestapel onvermijdelijk.
