MadSci Network: Botany |
In short YES! The big question though is how come mankind is extinct? What has caused it? If the catastrophe that removes humans from the Earth kills everything else, then that would mean.... no plants. If the event kills enough other animals and life, then the types of plants that survive will be effected. If humans are removed by some specific disease that effects only humans, then plants will carry on happily! Maybe the number and spread of different species will change, as farmed plants either take over or are taken over by the wild species.
