We Are on a Journey
Wherever you are, and whoever you may be, there is one thing in which you and I are just alike at this moment, and in all the moments of our existence. We are not at rest; we are on a journey.
Our life is a movement, a tendency, a steady ceaseless progress toward an unseen goal. We are gaining something, or losing something, everyday. Even when our position and our character seem to remain precisely the same, they are changing. For the mere advance of time is a change. It is not the same thing to have a bare field in January and in July. The season makes the difference. The limitations that are childlike in the children are childish in the man.
Everything that we do is a step in one direction or another. Even the failure to do something is in itself a deed. It sets us forward or backward. The action of the negative pole of a magnetic needle is just as real as the action of the positive pole. To decline is to accept -- the other alternative.
Are you nearer to your port today than you were yesterday? Yes, -- you must be a little nearer to some port or other; for since your ship was first launched upon the sea of life, you have never been still for a single moment; the sea is too deep, and you could not find an anchorage if you would; there can be no pause until you come into port.
Balance of Nature
All the different plants and animals in a natural world are in a state of balance. This balance is achieved by the plants and animals interacting with each other and with their non-living surroundings. An example of a natural community is woodland, which is usually dominated by a particular species of plant, such as the oak tree in an oak wood. The oak tree in this example is therefore called the dominant species but there are also many other types of plants, such as bushes, small trees, mosses, lichens and algae.
The plants of a community use carbon dioxide, oxygen, water and nitrogen to build up their tissues using energy in the form of sunlight. The plant tissues form food for the plant-eating animals which are in turn eaten by the flesh-eating animals. Thus plants produce the basic food supply for all the animals of a community. The animals themselves are the consumers, and are either herbivores or carnivores.
Examples of herbivores in a woodland community are rabbits, deer, mice, snails, and insects. The herbivores are sometimes eaten by the carnivores. Woodland carnivores are of all sizes, from insects to animals like owls, and foxes. Some carnivores feed on herbivores, some feed on the smaller carnivores, while some feed on both. These food relationships between the different members of the community are known as food chains or food webs. All food chains start with plants. The links of the chain are formed by the herbivores that eat the plants and the carnivores that feed on the herbivores.
