Material world and living world

Time to remember

In some place, we living beings dwell.
We need a space to live in the material world. Let us consider some examples:

1.The atmosphere is the place where birds spend part of their time, and where many microorganisms live permanently.

2.Among the rocks, live several kinds of spiders

3.In the sand, crabs live. They spend their days in holes or moving side to side.

4. In the seawater, live many species of fish, plants, microorganisms and even the biggest mammal, the whale.

The list continues, but remember that these are material spaces (air, water, rocks, sand, etc.). However, in their materiality, they offer conditions that make like possible.

It is the case of the atmosphere. In the primordial times of our planet, it had no oxygen. Primitive forms of life enriched our atmosphere with this gas, allowing the existence of more developed forms of life, including ours.

Our material world is thus different than that one in Mars, despite many similarities between the two planets.

This is the base of the Gaia Theory: primitive forms of life transforming the material space of a planet in order to make possible the existence of more developed forms of life.

 

 

Tree “dirtied” the sidewalk with leaves, branches, seeds and fruits_2nd vision

Our web site aims to find solutions, so that trees living in urban environments do not be cut down unnecessarily. The text presented last December pointed out an idealistic solution to keep fruit-bearing trees in the cities, saying that gathering leaves, branches, seeds and fruits from the ground is a privilege given to good will and conscious people.

Obviously this is just one side of the question. There are other points that we could discuss here, therefore this text is called “2nd vision”. With good reason, a reader made a comment on December’s text, stating that “if fruits are not gathered from the ground, they will become nourishment, especially to rats!”

Let us go to the facts: in nature, a fruit-bearing tree let its fruits fall on the soil, and these will serve, among other things, as food for wild animals. Birds, squirrels and other rodents will be benefited from the fruits. The picture below shows a mango tree in the woods. Note how many fruits are splattered over the ground, during the spring and summer seasons.

a

If we plant a tree of this species (mango tree) in a sidewalk, the fact will repeat itself. In the warm seasons, fruits will fall on the ground in a plentiful manner, if not harvested before. Fruits in sidewalks roll over when they fall, and move rapidly by the action of wind and rain. They may clog drains and prevent rain waters of being collected by the subterranean pipework, and flooding can happen therefore. See below the photo of a drain covered by leaves and fruits.

b

Note that the mangos, enhanced with colors in the photo, are splitting. If nobody takes them from the sidewalk, they might serve as food to rats, which are commonly found in cities and are capable of transmitting diseases to us, human beings. We have raised, therefore, two important urban problems: flooding and rodents proliferation. Now let us analyze suitable solutions.

c

To sweep streets and put leaves and fruits in plastic bags is an immediate solution. See in the picture above how a clean drain looks like. See the bag with all the gathered material that was on and around the drain.

Remembering the reader’s comment that “good sense is necessary when planting a tree”, we can propose two more solutions. First is not to plant fruit-bearing trees in urban sidewalks, but in suitable places (parks or planned gardens).

Another initiative is to choose suitable species for urban environments before planting. For already existing fruit-bearing trees, a constant maintenance is absolutely necessary. It is not fair to plant a tree in an environment created by men, for men’s use (cities) and later hand this tree to the care of “Mother Nature”.

d

It is a pity to see delicious fruits like these ones in the photo, just thrown on the ground. An urban harvesting program, efficiently handled is another proposal to solve this problem. Volunteer groups or paid businesses could do a systematic harvesting job, to calendar. This would meet the commitment to keep the urban environment clean and at the same time protect trees from being unnecessarily cut down.

New year, new attitudes

New year, new attitudes.
A year is gone, a new year is beginning.

What about planting a tree in 2017 ? Besides enlarging the green area of your city, you will breathe a cleaner air. Imagine that in 2023 you will be able to seat under its shadow… Isn’t it a wonderful motivation ?

Take trash recycling seriously. Encourage other people to do it, especially those who are unaware of its benefits. There is nothing worse to the cities or to Nature than litter out of its place !

Walk more and ride your bike, also for small shopping. There will be benefits for your health and for your pocket, besides saving some gas and polluting less the atmosphere.

A 2017 plenty of small accomplishments like these could turn it into one of the happiest years of our lives !! Happy 2017 !!

Tree “dirtied” the sidewalk with leaves, branches, seeds and fruits

Before coming here, we, the leaves, produced lots of oxygen for you to breathe !

To live means: to get nourished, to rest and to take care of our health and personal hygiene. These are the human bare necessities ! All the remaining activities (work, study, entertainment, etc.) come right after these basic needs were satisfied.

Personal hygiene is a very important issue in our lives. We know that if we don’t wash our hands before eating, we might get sick. If we don’t wash our body, we might get skin problems. If we don’t use deodorant, we risk smelling bad and bothering other people.

Another aspect of our personal hygiene are the clothes we wear. Dirty clothes may raise health problems, too. Then comes bed linen, followed by the room and house where we live. If they are not constantly cleaned, we risk getting sick. Example is the dust left on furniture, which can raise breathing problems.

When we get out of our home, our hygiene guidelines start to judge other places: public means of transportation, squares, streets and sidewalks. We could say “the bus was clean”, or “the square was dirty: empty packages were spread on the ground”. But, what about streets and sidewalks ? What make them dirty or clean ?

This is the point. Trees let leaves and branches, seeds and fruits fall on the ground. According to our hygiene habits applied at home, these items would be “filth” to be swept, put in bags and brought far away. If we keep thinking like this, it’s better not to have trees around. Hygiene is costly, why then have such additional work ?

Trees, however, have the right to exist and are necessary to our survival. Leaves on the ground are not filth. They are evidence that a tree generated oxygen for you to live. While gathering leaves, branches, seeds and fruits you will be valuing life itself. Don’t see it as an annoyance, but as a privilege given to good will and conscious people !

Nature and Time

The thirtieth:
Time to remember

Article published in December 2013:

A baby is born and takes 15 years to reach an adult’s height. When a puppy dog is born, it takes roughly 15 months to look like an adult dog. Time goes by to everyone, in the same way… however each species of the animal kingdom answers in a different way.

Among trees happens the same thing. While an avocado tree grows rapidly in its first years of life, a brazil wood tree shows a much slower growth in the same period.

This could be a motivation not to plant it and to chose a tree with a faster growth rate, instead. With this option, endangered species (which is the case of the brazil wood tree) have more difficulty to recover the space they had in the past, and remain under threat.

Let us re-think our attitude when we plant… Let us remember that time acquires different dimensions to the living beings: wheter a bacterium, a puppy dog, we, human beings or the various species of plants and trees.

Nature and her rules

The thirtieth:
Time to remember

Let us remember that Nature also has her rules !
Article published in November 2013:

For us she is Mother Nature, and we all know, she does not issue environmental conformity certificates. Neither recognizes governments nor borders between countries. That’s because Nature has its own rules, which are supreme. One of them is to restore itself. When not touched by humans, Nature tends to a self-restoring equilibrium. Case in point are cities of ancient civilizations which were abandoned long ago. Centuries later, they were found covered by plants. Nature just does it. And, in the absence of human interference, nature exists in its primitive state.

One word, two concepts

The thirtieth:
Time to remember

Article published in October 2013:

Imagine a campfire burning dried branches of wood to warm a soup vessel. This scene, so common to our ancestors, describes the use of “biomass as a fuel”. In this case, the dried branches are the biomass, and burning them means utilize branches of wood as a fuel.

Now imagine a forest and their trees, animals, fungi, microorganisms and bacteria. This means, the total quantity of anything who bears life. This total quantity, which can be measured, is also called biomass. And it can be measured separately (animals only, plants only, etc.).

When you read articles in newspapers and magazines, you will identify by context in what sense this word is being used. A single word holds two concepts: related but different, however.

Why trees don’t walk

Let us remember why trees don’t walk !

Trees produce oxygen and need lots of water to accomplish this task. They act as a lab, that processes a chemical reaction (photosynthesis), where the input substances are carbon dioxide and water and the output substances are carbohydrate and oxygen.

In order to have plenty of water, their roots are below the earth, where they get the necessary amount of water. This make them different from animals (and from us, humans), those who do not produce oxygen. Since we need less water than trees, we don’t need to be always attached to the earth. We are portable, we take in our body the water we need.

Trees do also breath like we do (they take oxygen from the air and give back carbon dioxide), but in parallel they produce oxygen in the presence of sunlight. When you water your tree, always remember that it will give us back its best: oxygen for us to breath.

Tree did interfere with electric wiring

 

09_September (7)

 

The use of electricity by human beings is a recent phenomenon. In the year 1801, Alessandro Volta presented to Napoleon Bonaparte his invention, a rudimentary electric battery. Since then, electricity and its applications did revolutionize the way we live.

Meanwhile, cities grew and became more and more complex. And to benefit from this technological advantage, an electric current distribution network was created. This happened initially by means of wires hanging on poles and later by subterranean cables.

It is difficult to imagine a city without electricity, and also a city without trees. We need both for our well-being. The systematic pruning of large size trees in urban areas may be a solution when electric cables interfere with tree branches.

Planned planting, by choosing a proper place and species, so trees do not interfere with the wiring, is also a feasible and positive attitude. Another possibility is the creation of exclusive spaces for trees (urban fields) and another space for wirings (subterranean cables or planned poles, which do not interact with branches).

Put these ideas to practice ? To do this, a major awareness effort must take place, towards municipal authorities and common citizens. Pruning trees means work, and dedicating urban grounds to trees or changing to subterranean cables involve high costs. Nevertheless, the results would bring an incomparable lift in the quality of life of a city.

 

Plant a tree today

In August 2013 the following text has been published, with a sticker mentioning:
Plant a tree today
Care today
Tomorrow will be a better day !

Dear Reader,
Planting endangered native trees in the cities should be followed by the act of taking care of these trees. Simply planting a seed or a small plant in the soil and let it grow may show no results. A tree starting its life cycle is like a newborn, it is exposed to many dangers. Someone may just pull the small plant from the soil. A long drought period may determine the plant’s death. Other natural enemies may also finish with it: locusts, caterpillars, or ants, for example. The presence of someone taking care of the tree is as important as the act of seeding or planting it, especially in the first year of life.
