What if plants do not only need the card measured resources such as nutrients, minerals, CO2, O2, sunlight and water? What if plans also need love, care, companionship, compassion and other intangible conditions? How about sound waves, what if plants need those too? What if plants are affected by the singing of the birds in a positive way? It would be quite interesting not only to study such conditions and their effect on plants, but also to use such knowledge that we come up with in order to devise systems by which we can care for plants. For instance, if in agriculture we know that a specific kind of crop or fruit tree needs such an amount of nitrogen, how about also knowing that it needs such specific sound waves in order to bear good fruit? That would be a completely new dimension in agriculture. I hope that when such time comes, sound requirements of a plant would be provided to it through natural means such as the singing of birds rather than using electronic devices that emit specific frequencies of sound waves in a farm.
Types of Thieves
Some organisms may be specialized in feeding on a particular type of plant, such as the silkworm and the mulberry tree leaves. Other organisms may feed on a variety of plants and animals. Similarly, thieves may specialize and 'prey' on particular types of robbery. Some thieves would be pickpockets that specialize on picking pockets. Others might be burglars who break into houses and rob their contents. Still other types of thieves might be those who steal bags from pedestrians. Yet other even more dangerous types may threaten to use force in order to take your belongings right before your very eyes. There are of course thieves who are 'generalists', they do not specialize in a particular type of robbery yet 'feed' on a variety of different types.
