Ban fire-prone, water-hogging eucalyptus in California.

Water-thirsty Eucalyptus trees suck up all the water from the ground, robbing all other plants of water. They make no sense in California; their wood is not good lumber. They often fall over and are called "widow makers". They easily catch fire, as they are full of oil. They make no sense in fire-prone, drought-ravaged areas like California. That's why they're banned in countries like South Africa. Ban their planting and dig them out now!
