Translation:
Harassed by famine and excessive taxes, people will resort to eating leaves, roots, flesh, wild honey, fruits, flowers and seeds. Struck by drought, they will become completely ruined.
Purport:
Srimad-Bhagavatam authoritatively describes the future of our planet. Just as a leaf disconnected from a plant or tree dries up, withers and disintegrates, when human society is disconnected from the Supreme Lord it withers up and disintegrates in violence and chaos. Despite our computers and rockets, if the Supreme Lord does not send rain we shall all starve.
