(YNetNews) The planting of ten of thousands of olive trees in arid areas in Israel have proved highly beneficial, according to a study which said the trees provide shade for animals, purge the air and even produce excellent olive oil.

The study was conducted by the Faculty of Agriculture at the Hebrew University in Jerusalem, with the help of the Agricultural Research Organization. Dr. Zohar Kerem, head of the olive oil research lab in the faculty’s biochemistry institute, who participated in the study, explained that they followed tree-plantings in Israel’s desert areas.

“Olive trees are not very picky,” Kerem said, adding that they can thrive under extreme weather conditions and require very little care and water. Olive trees, he noted, greatly benefit the environment by reducing the atmospheric levels of CO2.
