healthy cows eat grass and make methane

/healthy cows eat grass and make methane:
Israeli Researchers Cut Air Pollution
by Reducing Gas Output from Cows
[Judy Siegel-Itzkovich 2020 May 14]
. the author of this news supposes that
if a researcher studies the origin of cow germs
(diet vs germs given by mother)
it must be to control a greenhouse gas,
but I couldn't find such a concern
mentioned in the reference;
and, that is as it should be; because,
healthy, happy cows eat grass not grains;
and fermenting grass makes a lot of methane.

Israel advances desalination

11: pol/desalination/Israel advances desalination:
desalination can be mainstreamed:
. Israel desalinizes water for a cost of
53 cents per cubic meter;
desalinizing 1,000 US gallons (3,800 L) of water
can cost as little as $3 .
. modern technologies, such as
the Seawater Greenhouse,
use solar energy to desalinate seawater
for agriculture and drinking uses
in an extremely cost-effective manner.
alternet 2010:
. by 2014, Israel's desalination plants
might provide 33% of their drinking water.
. reverse osmosis technology
is used by the Hadera plant
(the world's largest using such technology);
it does not involve heating the sea water .
