The raising of livestock is a major economic activity in semiarid lands, where grasses are generally the dominant type of natural vegetation.

Dad is from La Union, a rural area approximately 230 kilometres north of the capital Manila, and where most people live off the land, raising and selling poultry and livestock.

If you cut down on meat, you will be 'saving food', since raising livestock costs more plant material than the energy and nutrition you would get from eating the plants themselves.
