2021 Earth Day: 30 Fascinating facts that will raise your awareness related to environmental issues
On April 22, Earth Day will be celebrated all over the world - a holiday in which it is worth thinking about the future of our planet and what we can do for a common home. This tradition originated in 1970 at the initiative of US Senator Gaylord Nelson, whose goal was to draw public attention to the problems of environmental pollution. On the eve of the holiday, we will share with you the most interesting facts about the Earth.
Earth Day was founded by US Senator Gaylord Nelson in 1970 to awaken the political class from its disinterest in the environment and was celebrated in its first year by about 20 million Americans, mostly young people. and very young. After 2 decades, in 1990, over 200 million people in 141 countries turned Earth Day into a major event in human history, by joining them in the desire to advocate for a better future for our planet, and in year 2009,
The United Nations (UN) has declared April 22 as the official holiday of planet Earth and a common expression of everyone's desire to build a stable society for a cleaner and greener future. The genesis of the Earth took place several billion years ago from a cloud of dust and gas that revolved around the sun and is the third planet from the sun with a particular constitution in the solar system.
Bemorepanda collected some interesting facts for you.
1. The core of the Earth contains so much gold, which will be enough to cover the entire surface of our planet by almost 45 centimeters.
2. The inner core of the Earth has a radius of about 1220 kilometers, which is comparable to 70% of the radius of the Moon. In addition, based on geophysical and geochemical methods, there is an assumption that the inner core of our planet is about the same temperature as the Sun.
3. Lightning strikes the earth on our planet more than 8.6 million times a day.
4. Prior to space travel, the Earth was often depicted as a green world. Science fiction writer Frank Paul is believed to be the first to depict a cloudless blue planet with well-defined land on the back of the July 1940 issue of Amazing Stories magazine.
5. Scientific evidence indicates that the Earth was formed from a solar nebula about 4.54 billion years ago. Life on the planet appeared about 4.25 billion years ago, that is, shortly after its origin.
6. The conditions for the existence of life on Earth preserve the ozone layer and the Earth's magnetic field, which weaken the solar radiation harmful to life.
7. The oceans occupy about 70.8% of the surface of our planet. Liquid water, which is essential for all known life forms, does not exist on the surface of any known planet in the solar system other than Earth.
8. The average speed of movement of lithospheric plates on Earth is approximately equal to the growth rate of nails on human hands. After 200-300 million years, hypothetically, all the continents of the planet will merge into the supercontinent Pangea Ultima.
9. The force of gravity at the poles of the Earth is greater than at the equator. A person who weighs 150.8 pounds (68.4 kg) at the North Pole will weigh 400 grams less while at the equator.
10. More than 68% of the Earth's freshwater is solid, including glaciers, snow cover and permafrost.
11. The Earth was first photographed from space in 1959 by the Explorer-6 apparatus. The first ever image of the entire Earth was captured by the orbital station Lunar Orbiter V on August 8, 1967.
12. The most massive extinction in the entire history of the Earth occurred at the end of the Permian period (298.9 ± 0.15 million years ago), when more than 90% of living things on the planet died.
13. The highest point on the Earth's surface is Mount Everest (8,848 m above sea level), and the deepest is the Mariana Trench (10,994 m below sea level).
14. The deadliest tsunami known to have occurred on 26 December 2004 in Southeast Asia was triggered by a 9.3 magnitude submarine earthquake in the Indian Ocean. The total death toll exceeded 235 thousand people.
15. The most toxic plant on Earth is the yew, a genus of small conifers. Every part of this tree is poisonous, with the exception of its berries, however, their seeds are also poisonous.
16. If all the water of the World Ocean is evenly distributed over the surface, then a layer with a thickness of more than 2.7 kilometers would be obtained. Of all the water that is on Earth, only 2.5% is fresh, the rest is salty.
17. Without the greenhouse effect, the Earth's average temperature would be between -18 and -23 ° C, given that it is actually 14.8 ° C. Without this thermal insulation effect, life on our planet most likely would not exist.
18. The atmosphere passes into interplanetary space gradually, in the exosphere, starting at an altitude of 500-1000 kilometers from the Earth's surface. By definition, the boundary between the atmosphere and space is drawn along the Karman line, located at an altitude of about 100 kilometers, above which air flights become completely impossible.
19. Human breathing becomes impossible at an altitude of 9 kilometers, although the atmosphere contains oxygen up to about 115 kilometers.
20. At an altitude of about 19-20 kilometers, the pressure of the atmosphere decreases so much that it leads to the boiling of water and interstitial fluid in the human body. Outside the pressurized cockpit at these heights, death occurs almost instantly.
21. The seas lose more water due to evaporation than they receive with precipitation, on land - vice versa. Water circulates continuously around the globe, while its total amount remains unchanged.
22. The rotation of the Earth occurs from west to east. Due to tidal acceleration, each next day is longer than the previous ones by an average of 29 nanoseconds.
23. Due to tidal synchronization, the Moon is moving away from the Earth by about 38 millimeters per year. Millions of years from now, this tiny change, as well as an increase in Earth's day of 23 microseconds per year, will result in significant changes. So, for example, in the Devonian period (about 410 million years ago) there were 400 days a year, and a day lasted 21.8 hours.
24. The largest tidal waves on Earth are observed in the Bay of Fundy in Canada and are 18 meters.
25. Earth is the only name for the planet that was not taken from Greco-Roman mythology.
26. Lake Baikal in Russia accounts for about 20% of all world reserves of fresh lake water. It is the deepest and oldest lake in the world.
27. The ice sheet in Antarctica contains about 80% of all freshwater on the planet. If it melts completely, the level of the World Ocean will rise by almost 60 meters.
28. The Earth moves around the Sun at a distance of about 150 million kilometers at a speed of almost 30 kilometers per second.
29. The driest place on earth is the Atacama Desert in Chile. In some places of this desert, rain falls once every several decades.
30. If the history of the Earth were presented in the form of a 24-hour segment, then the dinosaurs would have died out at 23:41, and human existence would begin at 23:54 and 43 seconds of the same day.

10 myths about how you really need to eat right, and why science decides everything here
There are many beliefs in our society that, upon closer examination, turn out to be prejudices. It is better not to eat animal milk, diabetics should not eat fruits, vegetarians will not last long without protein ... Let's figure out with the help of experts in the field of edible and inedible who is our enemy and who is our friend.
We have found and debunked several popular myths about proper nutrition.
At Bemorepanda, we liked the advice of the American writer, educator and health food activist Michael Pollan the best. It has only 7 words. Read with us.
Myth #1: Fresh fruits and vegetables are always healthier than canned, frozen, or dried ones.
Despite the strong opinion that "fresh is better", studies have shown that frozen, canned and dried fruits and vegetables can be just as nutritious and healthy as fresh ones.
“They can also help save money and be an easy way to ensure that families have consistent fruits and vegetables,” says Sarah Bleach, former director of food security and health equity at the USDA and professor of public health policy at the Harvard T. X. Chan. "One word of caution: Some types of canned, frozen, and dried foods contain ingredients such as sugar, saturated fat, and sodium, so be sure to read product labels and look for foods that are low in these additives."
Myth #2: All fats are bad.
When studies published in the late 1940s found a relationship between a high-fat diet and high blood cholesterol, experts decided that reducing the total amount of fat in the diet would reduce the risk of heart disease.
By the 1980s, doctors, health experts, the food industry, and the media were reporting that a low-fat diet could benefit everyone, although there was no conclusive evidence that it could prevent cardiovascular disease, overweight and obesity.
Dr. Vijaya Surampudi, assistant professor of medicine at UCLA's Center for Human Nutrition, says that as a result of the negative message about fat, many people - and food manufacturers - have begun to replace calories from fat with calories from refined carbohydrates (white flour and sugar).
Suffice it to recall the effect of low-calorie SnackWell cookies, when people began to overeat, confident that this is acceptable, since the food is dietary. “Instead of helping fellow citizens stay lean, this approach has led to an increase in overweight and obesity,” she explains.
In reality, Dr. Surampudi added, not all fats are bad. While some fats, including saturated and trans fats, can increase your risk of disease, healthy monounsaturated fats (found in olive and other vegetable oils, avocados, some nuts and seeds) and polyunsaturated fats (found in sunflower and other vegetable oils, walnuts) , fish and flaxseed) help reduce the risk.
"Good" fats are also important for providing energy, producing important hormones, maintaining cellular function, and absorbing certain nutrients.
If you see a product labeled "fat-free," don't automatically think it's healthy, says Dr. Surampudi. Instead, opt for foods with simple ingredients and no added sugar.
Myth #3: “Calories in, calories out” is the most important factor for long-term weight maintenance.
It's true that if you take in more calories than you burn, you're more likely to gain weight. And if you're burning more calories than you're consuming, you should be losing weight—at least in the short term.
However, the study does not suggest that eating more food will lead to sustained weight gain, i.e. obesity or obesity.
"Rather, it's the types of foods we eat that may be long-term drivers of these conditions," said Dr. Dariusz Mozaffarian, professor of nutrition and medicine at Tufts University's Friedman School of Nutrition Science and Policy.
Over-processed foods—refined starch snacks, cereals, crackers, energy bars, baked goods, soda, and sweets—can be especially harmful to weight gain because they digest quickly and fill the blood with glucose, fructose, and amino acids, which are converted into fat by the liver. Instead, maintaining a healthy weight requires a shift from counting calories to prioritizing healthy eating in general—quality over quantity.
Myth #4: People with type 2 diabetes shouldn't eat fruit.
This myth arose because fruit juices, which can raise blood sugar levels due to their high glucose and low fiber content, are confused with whole fruits.
However, it is not. Some studies show, for example, that those who consume one serving of whole fruits per day — especially blueberries, grapes, and apples — have a lower risk of developing type 2 diabetes.
According to other scientific sources, if you already have type 2 diabetes, then eating whole fruits can help you control your blood sugar levels.
It's time to dispel that myth, says Dr. Linda Shiue, GP and director of health nutrition and lifestyle at Kaiser Permanente San Francisco: Everyone, including type 2 diabetics, needs healthy nutrients found in fruit - fiber, vitamins , minerals and antioxidants.
Myth #5: Plant-based milk is healthier than animal-based milk.
There is an opinion that vegetable milk, for example, from oats, almonds, rice, is more useful and nutritious than cow's.
“That's just not true,” says Kathleen Merrigan, a professor of sustainable food systems at Arizona State University and a former US assistant secretary of agriculture. “Consider protein: Generally, cow’s milk has about eight grams of protein per cup, while almond milk has one to two grams and oat milk has about two to three grams per cup.”
Plant-based drinks can vary in nutritional value, Dr. Merrigan said, but many contain more added ingredients, such as sodium and sugar, that will degrade health faster than cow's milk.
Myth #6: White potatoes are unhealthy.
Potatoes are often frowned upon in the nutrition community due to their high glycemic index, which means they contain fast-digesting carbohydrates that raise blood sugar levels. However, potatoes may actually be good for your health, says Dafena Altema-Johnson, food community and public health program officer at the Johns Hopkins Center for a Better Future.
It is rich in vitamin C, potassium, fiber and other nutrients, especially when eaten with the skin. In addition, potatoes are inexpensive and available year-round in grocery stores, making this product more affordable. The most useful cooking methods are: frying, baking, boiling and air grilling.
Myth #7: Peanut foods should not be given to infants in their first years of life.
For a long time, experts have been telling new parents that the best way to prevent food allergies in children is to not feed them allergenic foods like peanuts or eggs for the first few years of life. But now, according to allergy experts, it's best to introduce peanut products to your child's diet as early as possible.
If your child does not have severe eczema or an identified food allergy, you can start introducing peanut products (such as water-diluted peanut butter, peanut puffs, or peanut powder, but not whole peanuts) at about 4-6 months, when your child is ready for solid food. “Start with two teaspoons of smooth peanut butter mixed with water, breast milk, or formula two to three times a week,” advises Dr. Ruchi Gupta, professor of pediatrics and director of the Feinberg Northwestern School of Medicine Center for Food Allergy and Asthma Research. . - If your baby has severe eczema, first ask your pediatrician or allergist about whether you can start giving peanut products at about 4 months.
It is also important to feed your baby a variety of foods in the first year of life to prevent food allergies,” says Dr. Gupta.
Myth #8: Plant protein is incomplete.
"Where do you get protein from?" is the #1 question vegans get asked,” says Christopher Gardner, a nutrition scientist and professor of medicine at Stanford University. The myth is that plants are completely lacking in certain amino acids, also known as the building blocks of proteins. But in fact, plant foods contain all 20 amino acids, including the nine essential, essential amino acids.”
“The only difference is that the ratio of these amino acids is not as ideal as in animal products. Therefore, to get an adequate portion of nutrients, you just need to eat a variety of plant foods throughout the day: beans, grains and nuts and consume enough protein in general. Most people in prosperous countries get everything they need: it's easier than many people think, ”says Dr. Gardner.
Myth #9: Eating soy-based foods can increase your risk of breast cancer.
The high doses of plant estrogens in soy, called isoflavones, stimulate the growth of breast tumor cells (according to animal studies).
“In humans, this association has not been confirmed,” says Dr. Frank B. Hu, professor and chair of nutrition at the Harvard T.H. Chan. So far, scientific evidence does not point to a link between soy consumption and the risk of developing breast cancer in humans.
In contrast, consumption of soy-based foods and beverages—such as tofu, tempeh, edamame, miso, and soy milk—may even be protective, reduce the risk of development, and increase survival in this disease. Soy products are also a source of beneficial nutrients associated with a reduced risk of heart disease, including high-quality protein, fiber, vitamins and minerals, adds Dr. Hu. “The results of the study are clear: feel free to include soy products in your diet.”
Myth #10: Basic nutritional guidelines change all the time—and by a lot.
“That’s not true,” says Dr. Marion Nestle, Professor Emeritus in the Department of Nutrition, Nutritional Research, and Public Health at New York University. - In the 1950s, the first dietary recommendations for the prevention of obesity, type 2 diabetes, cardiovascular disease, etc. contained advice to balance calories and minimize foods high in saturated fat, salt, and sugar. Modern dietary guidelines call for the same.”
Yes, science is developing, but the rules of healthy eating remain unchanged. Writer Michael Pollan summed it up in seven simple words: “Eat food. Not too much. Mostly plants. According to Dr. Nestle, this council worked 70 years ago and continues to work today. And it leaves plenty of room for eating the foods you love.
