5 Things that are not known about our planet

caves... to plummet!

The Vrtoglavica cave, in Slovenia, has the deepest vertical chasm: 630 m. It would fit the Empire State Building in New York or the Petronas Towers in Malaysia. But the Sotano de las Golondrinas, in Mexico, are the largest cavity in the world because it is very wide. Its 333 m depth could house the Chrysler Building in New York (319 m); in it the BASE jump is practiced. 2. Dinosaurs that ... they know chicken! If you want to know what the terrible dinosaur Tyrannosaurus Rex knew, you just have to eat chicken. Chickens are the current descendants of the TRex!

4. The most sticky thing is to throw furious ants The five days of parties of the Entroido de Laza, in Galicia, people dress up and have fun. One of the hobbies is collecting dirt with ants, sprinkling them with vinegar to irritate them and throwing dirt and ants at people, as well as mud, ash, flour, water ... Do not do it at home please. 5. Crazy sports: with the lady in tow

3. How cool is cool! The moonfish (mola mola) is the heaviest bone fish in the world and the one that makes the most bulk. The larger ones measure more than 4 m in length and can weigh up to 2235 kg, almost like a small van. He likes to float in the ocean, as if he sunbathed, and they call him moonfish because of its rounded shape. He loves to eat jellyfish and females can carry 300 eggs. They are not very travelers, but a sunfish swam from the coast of New England, in the United States, to the Caribbean and the Gulf of Mexico.

Every July, in Sonkajarvi, Finland, burly men carry a woman on their backs and compete in an obstacle course at the World Wives Charging Championships. The couple with the best time wins the woman's weight in beer. .

Greenhouse effect The "greenhouse effect" is the heating that occurs when certain gases in the Earth's atmosphere retain heat. These gases let in light but keep the heat like the glass walls of a greenhouse.

September 5, 2010 The glaciers are melting, the sea level is rising, the jungles are drying up and the fauna and flora struggle to keep up with this rhythm. It is increasingly evident that humans have caused most of the warming of the last century, through the emission of gases that retain heat, to enhance our modern life. We call greenhouse gases and their levels are getting higher, now and in the last 65,000 years. We call the result global warming but it is causing a series of changes in Earth's climate or long-term weather patterns that vary by location. As the Earth revolves every day, this new heat turns in turn picking up the moisture from the oceans, increasing here and settling there. The rhythm of the climate to which all living beings have become accustomed is changing.

First, sunlight shines on the earth's surface, where it is absorbed and then returns to the atmosphere in the form of heat. In the atmosphere, greenhouse gases retain some of this heat and the rest escapes into space. The more greenhouse gases, the more heat is retained. Scientists know the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be cooler if there were no atmosphere. This greenhouse effect is what makes the climate on Earth suitable for life. Without it, the surface of the Earth would be about 60 degrees Fahrenheit cooler.

Are temperature changes not natural? The global average temperature and the concentrations of carbon dioxide (one of the main greenhouse gases) have fluctuated in a cycle of hundreds of thousands of years as the position of the Earth has varied with respect to the sun. As a result, different ice ages have occurred. However, for thousands of years, GHG emissions into the atmosphere have been offset by GHGs that are naturally absorbed. Therefore, GHG concentrations and temperature have been quite stable. This stability has allowed human civilization to develop in a consistent climate.

Why is it worrying? The rapid increase in greenhouse gases is a problem because climate is changing so fast that some living things cannot adapt. Likewise, a new and more unpredictable climate imposes unique challenges for all types of life. Historically, the Earth's climate has oscillated between temperatures like those we have today and temperatures so cold that large ice sheets covered most of North America and Europe. The difference between the average global temperatures and during the ice ages is only 9 degrees Fahrenheit and these oscillations occurred slowly, over the course of hundreds of thousands of years.

ÂżWhat is it? Environmental contamination refers to the presence in the environment of any agent (physical, chemical or biological) or of a combination of several agents in places, forms and concentrations such that they are or may be harmful to health, safety or health. welfare of the population, or else, that may be harmful to plant or animal life, or prevent the normal use of properties and places of recreation and enjoyment thereof. Environmental pollution is also the incorporation into the receiving bodies of solid, liquid or gaseous substances, or mixtures thereof, provided that they unfavorably alter the natural conditions thereof, or that they may affect health, hygiene or well-being. As the power of man over nature increases and new needs appear as a consequence of life in society, the environment that surrounds it deteriorates more and more.

Types  Water pollution: Is the incorporation into the water of foreign matter, such as microorganisms, chemicals, industrial waste, and other types or wastewater. These materials deteriorate the water quality and make it useless for the intended uses. Soil pollution: the incorporation into the soil of foreign matter, such as garbage, toxic waste, chemical products, and industrial waste.

 Soil pollution Produces a physical, chemical and biological imbalance that negatively affects plants, animals and humans.

 Air pollution: Is the harmful addition to the atmosphere of toxic gases, CO, or others that affect the normal development of plants, animals and negatively affect the health of humans

Cause Household solid waste • industrial solid waste • excess fertilizer and chemical products • felling • burning • garbage • carbon monoxide from vehicles • wastewater from sewage or polluted water to the sea or rivers

Effects of radioactivity The effects of radioactivity on living beings are harmful to their physical integrity. They can be immediate or delayed, depending on the dose. When the human body suddenly receives high doses of radiation, death can ensue. High amounts received in small and spaced fractions produce late effects, such as leukemia, cancers, cataracts and other degenerative processes. Low doses and spaced in time can produce late effects or abnormalities in the next generations.

Reciclaje It is a process whose objective is to convert waste into new products or raw material for later use. Thanks to recycling, the disuse of potentially useful materials is prevented, the consumption of new raw material is reduced, as well as reducing the use of energy, air pollution (through incineration) and water (through landfills) , as well as reduce greenhouse gas emissions compared to the production of plastics. Recycling is a key component in the reduction of contemporary waste and is the third component of the 3R ("Reduce, Reuse and Recycle").  Pollutants In order to talk about recycling, it is important to know what the contaminating vectors are in which we must be aware so as to take care of the environment and eliminate global pollution. Of which we refer: 1 - Air: where all the odors and pollutants of factories, traffic and, among other things, accumulate. - Water: where society pollutes more often because there, society is responsible for throwing away its waste, throwing away polluting products and doing its industrial jobs. - Use of energy: in which, as society grows, manufacturing of any kind that contaminates the environment is generated.
