We all love metals. You’ll probably have something metallic in your wallet. Or how about the keys to your home. Your car. Your bike. Your kitchen appliances. Kitchen utensils. Your tools. A can of beer in your fridge. Metal is the cornerstone of our life. But it’s heavy. Especially the ones mentioned in the list below.
In 2012 the nuclear power capacity worldwide rose to 372.5 gigawatts. In total 437 nuclear power reactors were operating worldwide in 31 countries. Although some countries like Germany and Japan have said to permanently shut down all reactors, others, such as China, India, Saudi Arabia and Russia will open new nuclear reactors in order to satisfy its energy demand.
Bauxite is the world’s primary source of aluminium. Almost all metallic aluminium is produced from the ore bauxite. Bauxite occurs as a weathering product of low iron and silica bedrock in the tropics. So where can we find the most important countries by bauxite production?
Climbing mountains isn’t something for the fainthearted. It’s quite dangerous even for experienced climbers. But for many people reaching the summit of a notable peak by foot is a number one goal in life. These mountaineers might be interested in climbing the highest mountains in Antarctica. This is as cool as it can get.
Cotton is the most widely used natural fiber in clothing today. It’s been cultivated in both the Old and the New World for thousands of years. Mexico, India, Pakistan (Indus Valley Civilization), China all were and still are notable cotton producing countries.
Water. We can’t do without it. It covers more than 70% of the Earth’s surface. The human body contains from 55% to 78% water. It’s suggested to drink around 6 glasses of water a day, around 2 liters. But water is also an important generator of energy. So what are the largest water reservoirs by volume?
The state of Utah has a lot to offer when it comes to the most impressive rock formations on earth. They can be seen in Utah’s National Parks, such as Zion, Bryce Canyon, Canyonlands, Capitol Reef, the north rim of the Grand Canyon and Arches National Parks. Arches National Park is home to some of the world’s longest natural arches.
If you don’t like crowds, then you might like to take a look at this list of least densely populated countries. If you consider emigrating to one of those countries you’ve got to be prepared to live your life in harsh conditions. Be it a steamy jungle, a dry desert or a freezing cold ice plain. The good thing is that your next door neighbors live miles away.
Hydropower is the most widely used form of renewable energy. It soon accounts for approximately 20% of global electricity generation and it is expected to grow to 40% in the next 25 years. Hydropower is a flexible source of energy. It’s cost efficient and sustainable as power plants can easily function for more than 50 years.
Lithium. This silver-white metal belongs to the least dense solid elements. It’s highly reactive and flammable. Lithium and its compounds have a number of industrial applications, including glass and ceramics and, increasingly popular, lithium-ion batteries. For the latter reason, lithium is often referred to as ‘the next commodity’. So it’s relevant to know which countries have a rich lithium supply.
Africa is the second largest continent in the world stretching from the Mediterranean Sea in the north to Cape Town in the south. It covers around 20 percent of the total land area of the world. The continent gave birth to the human race (Homo Sapiens) approximately 200,000 years ago. And although the total population of Africa now exceeds one billion people, this fascinating continent is also home of some of the largest national parks in the world.
On a grey and rainy morning like this, one could easily long for the sunniest places on earth. The sun plays an important role in the lives of many. As a matter of fact, the existence of life on Earth is fueled by light from the sun. The combination of sunlight, carbon dioxide and water enables plants to produce sugars, a process called photosynthesis.
There are around 10,000 bird species. Birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs and a lightweight skeleton. And probably the most significant aspect of a bird: they have wings that enable them to fly. Some birds use these wings to migrate annually, others use them for hunting prey. The birds in our next list are the fastest birds in the world.
Volcanoes play a major role in shaping the surface of the earth. At almost any moment somewhere in the world a volcano erupts. Volcanic eruptions can pose many risks, not necessarily in the direct vicinity of the volcano. Everyone will remember the eruption of Eyjafjallajökul in Iceland in 2010. This eruption didn’t claim any victims, but the volcanic ash disrupted air travel in the northern Atlantic for weeks.
It is estimated that 50% of the world’s population lives in a city. This rate is believed to grow to 70% in the 2050’s. This phenomenal growth can be attributed to the lure of not just economic opportunities, but also to loss of farmland, pollution or conflict. Moreover the attraction and anonymity of hedonistic pleasures that cities have to offer play an important role in a world that satisfies the needs of the modern individualist.
Millions of people worldwide depend heavily on lakes. Lakes provide them with fresh water and food. Many settlements were built in the close vicinity of a lake. From a biologist’s perspective lakes are interesting too, since they contain a rich biodiversity. Freshwater ecosystems occupy only 0,8 percent of the earth’s surface, but harbor nearly 6 percent of all known species. In 1932, the Dutch even created a lake (IJsselmeer) with a surface of 1.100 km², making it the largest lake in Westen Europe. But where can we find the largest lakes in the world? Here’s a top 10!
The grey wolf (Canis Lupus) once was an abundant species in the arctic and subarctic zones. Nowadays the total wolf population is reduced to about one third because of the fear over attacks to humans and the preservation of livestock. Attacks have occurred, although they are rare. In Europe, the grey wolf was almost extinct, but a large scale recovery programme began after the 1950’s. The conservation status of the grey wolf now is of least concern according to the Red List of Threatened Species (IUCN). Wolves are even spotted in densily populated areas such as the Netherlands or the German Ruhrgebiet. However, these numbers not close to the numbers in our next list. Check the countries by wolf population!
How low can you go without entering the earth’s crust? Well, like James Cameron you can go to the Mariana Trench inside the belly of a submersible vessel, but leaving the vessel at a depth of 37,700 feet isn’t really a smart thing to do. The pressure would be absolutely inbearible, and you wouldn’t see a thing because of the darkness. It’s much easier and safer to stay on the continent and visit one of the next spots. Moreover, these places normally are hot and dry and in some cases you can float on the salt lakes. These are the lowest places on earth!
Tree forests cover approximately 30 procent of the total land area of the world. Forests are a habitat for many organisms. About 90 procent of the world’s biodiversity is found in forests. They function as carbon storage and they are often reffered to as the lungs of the world. And forests are economically valuable too. Countries such as Brazil or Indonesia capitalize on their natural resources. Deforesting is a threat however and the percentage of the forested area as a part of the total land area is declining. Still there are many forest rich countries. Here’s a list of the most forested countries of the world!
Driving your car means you decide when and where to go. This sense of ultimate freedom rapidly stops when you enter the cities in our next list. First of all you’ve got to find a parking spot and once you’ve finally managed to squirm your car somewhere in a dark, gas polluted parking garage, you’ll soon discover that your wallet won’t be really happy. The parking rates in this list are astronomous. Check the next list most expensive cities to park. Parking rates on a monthly basis and in US dollars. The good news is that most cities have an excellent subway system, so you can reconsider an alternative.
Hurricane Sandy is about to hit the city that never sleeps. Almost 400.000 residents are evacuated, and it is estimated that about 50 million people will be affected by Sandy. In terms of diameter of Atlantic hurricanes, Sandy already set a new record with an astounding 930 miles. Hurricane Sandy might be the prelude to enormous economic loss, since it will come ashore on the economically most important region of the USA. Not only in terms of direct damages, but also indirectly by shutting down public transport, Dow Jones and major international airports. ‘Frankenstorm’ might enter our next list of costliest hurricanes in the next 24 hours.
America has a lot to offer when it comes to exploring nature. The broad variety of unique landscapes attracts many tourist annually. To protect and conserve these regions for future generations the concept of a national park was established. In 1872 Yellowstone Park was the first National Park. Now National Parks in the USA account for 2,2% of its territory. What are the largest national parks in the USA. Find out in our next top 10!

We love rivers. Rivers are responsible for bridges and tunnels. Economies were built on the existence of mighty rivers that connected cities to the rest of civilization strategically. Rivers create unique eco-systems. Rivers are part of the hydrological cycle. Rivers end in beautiful estuaria or deltas, in oceans and sometimnes they simply evaporate before reaching the sea. They are earth’s vascular system. What are the longest rivers of the world? Here’s a top 10!

The relation between humans and snakes has always been tense. Many people fear snakes and snakes have played an important role in many historic events and myths. The majority of these reptiles don’t pose a danger to humans, but some snakes, especially venomous snakes do. Last week an Australian teenager got bitten and was hospitalized. The snakes in our next list are very dangerous because of their venom. However, they are not necessarily the most dangerous snakes in the world. This top 10 most venomous snakes is all about the power of the venom, measured in LD50 (median lethal dose; (mg/kg)). Fear the snakes in this list!
