watch out!!

In the past to the problem of the nature, we did not pay him the sufficient atention for to realize that ourselves was destroying our ecosistem, some causes were the neglect of the wast that we generate to daily and the bad treatment that we give to the environment also, i think that they must create proyects for the care and the conservation ot ours habitat, because in some years it could not be habitable ecosistem.

About the topic to be discussed or presedents of the same is to think in not say that persons to do if not that all start to change by ourselves and improve the prospect of change. so be it the minor and minimal change its help to improve all from of point of view that they see it.

All live on the same planet and was created for have a quality and make an effort by those who inhabit for that this not damage so fast and we dont repent of the what happened in the social networks i realized that if we do not recycle the human life and animals life they do not will inhabit thu territory some causes its know like, not recycle plastic, papers or cans, these elements do not recyclable reach to the sea, where the aquatics animals by consumer it or by physical agression are dying.

There are persons that gave the same have throw on only paper on the floor, thinking that it was not big thing but really each paper form little by little in a montain of garbage and destroy ours place of life. There are people that not import the topic but there are people that if they care and they do not thought in today, they thought in a tomorrow, and they generated change.
When people care about the care they do campaings and strive for that others join and helps, not only we harm the nature throwing papers in the street, and do not recycle, also was the smoke of factories that damage the environment.

 Climate change is likely to exacerbate both natural disaters and conflicto over natural resourses
but the impact of climate into businesses and companies is bering underestimated.climate change dealtswith statistics of distribution of weather. patterns over  an extended period ot time decades millons of years, it can refer to a change in average weather conditins of the weather temporal variatonof the average long temperatures conditions.more or less extreme weather events.it is coused by factors such as biologica processes variation in solar radiaton received for earth, tectonic plates and volcanic eruptions they have also identified certain human activities as significant causes of recent climate changesoften called global warming .
scientists are actively working to understand the past and future climate through observations and theoretical models has complied a climate has complecations and continues to building  , based on geologica evidence from  thermal profiles of perforations 

removed deep accumlations ofice , register of flora and fauna, processes cores glaciers and melted , stable isotopos  and other analyzes of sediment layers and the records sea levels in the past, the instrumental recored providies  more recent data , the models de general circulation , (GCMS)supported by the phiscal sciences, are often used in the oretical approaches to match past climate data. make future prections and associate the causes and effect of climate change the companies have to develop new alternatives for planet care, for reduce the pas emtsstons and this way to have better control of it  

BOGOTA RIVER'S

Bogota River's

We can note that one of the most important rivers is highly polluted, for we humans are not aware of all the hurt we are causing to the environment.

For example:

Ø  Throwing garbage.

Ø  Cutting down trees.

Ø  Wasting water.

Ø  Toxic wastes that are thrown to the rivers

CONTAMINATION

Ø  The polluted waters of the Bogota river have caused high levels of microorganism and toxic metals in some foods.

Ø  Whit respect to the vegetation, the river has a low density of water macrophytes, because of the speed of water.

Ø  Chrome, especially in the area of the mouth the river Tunjuelo.

Ø  Lead, particularly in the sections Villapinzon.

Ø  Mercury, than ten years ago found in the analysis, reports today not because of his disappearance.

BACKGROUND OF POLLUTION BOGOTA REVER’S

Ø  The amount of waste strip in the river.

Ø  The rains down charged waste.

Ø  Toxic waste that the industries thrown in the river.

Whatever surprising result as some certain animals such as cows, sheep’s, dogs, and other took the river water.

Although one results have identified a reduction the water intake not a few sources in used in crop irrigation.

DECONTAMINATE OR STOP CONTAMINATING

The way out apparently be the decontamination of the Bogota river’s, however only a short term solution is to launch campaigns about uncontaminated to the can raising people about the great effects this may well of the future, all so be able genere habits for the environmental stewardship.

Environmental care 

In the last years, the people thought  about ways to care environmental because the humans introduced external substances into the environment. If we can't  be aware of this, there will be terrible consequences on people and the planet like destruction of the biodiversity, increased mortality of the humans and animal species, etc.

Some examples of contamination in our ecosystem are:

 -The ozone layer is the second layer of the Earth’s atmosphere. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals. The ozone layer is getting thinner because the factorie's smoke, car's smoke  and nuclear plants have damaged it . ''Ozone holes'' are popular names for areas of damage to the ozone layer but the scientists observed the first signs that the ozone layer starts to recover.

-Natural disasters are extreme, sudden events caused by environmental factors that injure people and damage property. Earthquakes, windstorms, floods, and disease all strike anywhere on earth, often without warning.

-Water Pollution: This example is one of the worst  because if we are not aware probably there would not be drinkable water and all the people will die. Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, getting dissolved in them. This degrades the quality of water.

To conclude it's necessary to be aware of what human race is doing to our home and what is the contribution of every one. The world is in danger and we have to take care of it. We are preventing pollution: recycling, throwing away the garbage in the trash can and not using public transport or cars.

Colombia against illegal mining



Being here in Bucaramanga, denouncing people live who are worried because many companies involved in illegal logging continue in this activity for a year.

I'm walking down the path of beautiful blue where I found the army, national police and prosecutors destroying three dredgers with that extracted emeralds.

In this area buy a pair of emeralds in the amount of money for their sale was inside a safe are doubled, he walked at least a kilometer and found dredgers where land was damaged and affected.


I went to talk to a spokesperson of the people who assures us that mining destroys the environment as for extraction harm entire hills, native species of flora and fauna, also generate hazardous waste such as acids and cyanides that harm the people generating many diseases.

to solve this problem the government is invited to show interest on illegal mining so that our environment does not disappear daily samll this is called illegal by the way they operate which is done without permission and without safety standards also suitable for the high and irreparable environmental impact.


My question is because it follows all the same after so many deaths and so much destruction of the environment, what is happening with illegal mining in Colombia? Why are there so many problems? What about the government does not take establishes rules on the matter? What communities can expect regarding illegal mining?.

This affair much to say and to debate but ultimately the goal should aim to find a solution for the state you can find a successful exit humanitarian problem that is causing mining.

MELTING GLACIERS

The conceit of glaents has origin in the frensh glacier a gives name the block or structure of frost that fut accumulate in certain areas of the chain or rige of mountans, on of the line of stame, the limit of the snow inmotelle. The part lower of an glaents collision in move, with a slip very slow and similar at an river.

CONCEQUENCES: Scarcity of earthwater, augmentation of the level of the sea, mortality in the animals that inhabit in the pole (bear pingüins, fur-bearing seal, walrus, wolf slow arctic, hare) 

CAUSES: Contamination of the environment by the humanbeing, use of  aerosoles is hurtful to cloak of ozone, the calefaction global this provoke an series of baters climatics in the earth, the augmentation in the activitys industrials that produce Co2 augmentation the quantity of radiation in the akull polars help the thaw.

SITUATIONS:

ARTIC: During the spring and the summer , form on the ice pons of wather owing the taw of the same. Anxious of the beauty of this phenomenon an study recent realize by investigators determine that the pons of wather every turn more presents are an omen of the bigs baters climatics that the expectation the ocean artic. This pons form on the ice absorb in greather degree  the hot of the sun, progeny an taw more accelerator. It has been verified that this bulky cloak it has been made more small, leave place a form new of ice

ARTANTIDA: In the artantida the principal preoccupation arise of the glaents of pine island, that this taw from long time age contributed to the augmentation of the level of the ocean in the last years, the rapid retrocession that it was suffer this glaents carried much a think that can collapse in any moment

CLIMATE AWARENESS

My opinion is that global warming is affecting the world, the greenhouse effect is getting worse because we are causing pollution and the world is entering crisis. We should raise awareness and inform us more on this subject, all of us should make a change in thinking and try to save this world. I have read and seen many animals and people die because of this problem that we ourselves have caused, I believe that the human being over-exploited natural resources and already some time ago we beginning to suffer the consequences is a serious problem that we face what do you do to help? Consider among all the climate change, it is time to worry about our future, we are ruining the only planet we have.We can do to change the other people. Before without the overall warming, the world was not in danger but today it Have is . For this cause I have a list of sentences for bad think in everything That we are doing. To end I need that we make the change that we want to see on earth, but this change duty to start fast before of that worse. Because time is ending and we is not doing nothing for prevent.

Six  actions that neutralize global warming:

·         reduce water consumption.

·         Recycle Waste.

·         promote reforestation or implementation of green areas in the cities

·         reduce the use of contaminants.

·         use hand sprayers instead of aerosols.

·         Change incandescent filament bulbs, they use almost all the electricity consumed in producing heat.

YET WE CAN SAVE THE WORLD!
