10 interesting facts about planet Earth that you may not have known . AI-Generated.
Millions of people around the world celebrate International Earth Day today, with which the United Nations wants to raise awareness about the importance of preserving our planet's natural resources and facing the challenges of climate change. The date chosen by the UN to honor the Earth recalls the events of April 22, 1970, when 20 million people took to the streets of major cities in the United States to protest the damage that human activities were causing to the Earth. environment. On the occasion of Earth Day, BBC Mundo reviews some fascinating facts about the planet we call our home. 1- The Earth is not a perfect sphere Our planet is usually represented as a perfect sphere, but that is not its precise shape. The Earth is flattened at the poles, so its shape is more like an ellipse than a circle. As happens on other planets, the effect of gravitation and centrifugal force produced by rotation on its axis generates polar flattening and equatorial widening. Thus, the diameter of the Earth at the equator is about 43 kilometers greater than the diameter from one pole to the other. 2- Water covers more than 70% of the Earth On Earth, water is found in solid, liquid and gaseous states. Furthermore, it covers three-quarters of the earth's surface in the form of swamps, lakes, rivers, seas and oceans. The latter contain around 97% of all the water on the planet. 3- The border between Earth and space is 100 kilometers high It is considered that the border between the atmosphere and space is called the Kármán Line, which is 100 km high. 75% of the atmospheric mass is found in the first 11 km of altitude from the sea surface. 4- The Earth is an iron planet Earth is the densest and fifth largest planet in the Solar System. The most present chemical elements are iron (around 32%), oxygen (around 30%), silicon (around 15%). Scientists believe that the Earth's core is composed primarily of iron (about 88%). 5- Earth is the only known planet with life The Earth is the only astronomical body in which we have been able to confirm that there is life. There are currently around 1.2 million cataloged species of animals, although scientists believe that is only a small percentage of the total. The Earth formed approximately 4.5 billion years ago and life has been present on it for much of that period. The physical properties of the Earth, its geological history and its orbit have allowed life to exist for millions of years. 6- Gravity is not the same in all places on Earth Our planet is not really in the shape of a sphere, but rather a shape closer to an ellipse. Furthermore, the Earth's soil is irregular and the mass of our planet is not distributed perfectly homogeneously. This causes variations in the value of the gravitational field. Thus, for example, as we move from the equator towards the poles, the intensity of the gravitational field gradually increases, although the difference is imperceptible to humans. 7- The Earth is a planet of extremes Our planet is full of contrasts. The variety of its geographical areas and climates means that practically each region has its own particularities. There are several candidates to be considered the warmest places on Earth, but the place with the highest temperature ever recorded is in Death Valley in the United States, where on July 10, 1913 the thermometer rose to 56.7°C. At the other end is Antarctica. At the Vostok station on July 31, 1983, the measuring instruments reached −89.2 °C. 8- The largest living structure on Earth The Great Barrier Reef, located off the coast of Australia, is the largest single structure made up of living organisms on the planet, to the point that it is the only one that can be seen from space. It extends for more than 2,000 kilometers and is home to thousands of marine species. In 1981, it was declared a World Heritage Site by UNESCO. 9- Earth is the only planet in the solar system with active tectonic plates The movement of these plates causes the surface of our planet to be constantly changing, being responsible for the formation of mountains, seismicity and volcanism. The cycle of these plates also plays an essential role in regulating the Earth's temperature, contributing to the recycling of greenhouse gases such as carbon dioxide, through the permanent renewal of the ocean floor. 10- The Earth has a protective shield The Earth's magnetic field acts as a shield against the continuous bombardment of particles from the Sun. This field extends from the Earth's inner core to the boundary where it meets the solar wind. Among other things, the magnetic field also helps the orientation of some animals and ours, with the use of compasses.

The Plastic Problem
Plastic pollution poses a significant threat to our planet, impacting oceans, wildlife, and freshwater ecosystems on a global scale. The South Pacific Garbage Patch, a massive accumulation of marine debris larger than the state of Texas, is just one example of the devastating effects of plastic pollution. This issue is not limited to oceans, as even the Great Lakes and the Mariana Trench are now facing the consequences of plastic waste. The exponential growth in plastic production has led to a surplus of waste, with microplastic pellets from manufacturing facilities finding their way into water bodies through accidental spills. These microplastics degrade over time, breaking down into smaller fragments that persist indefinitely.
