The great white shark (scientific name: Carcharodon carcharias) is not the biggest shark (that title goes to the whale shark), but they are the largest predatory fish on Earth. According to the Guinness World Records Book, full-grown adults are average 4.3-4.6 meters (14-15 feet) in length, and generally, weigh 520-770 kg (1,150-1,700 lb). But there are many (unconfirmed) claims of huge specimens up to 10 meters (33 feet) in length. Newspapers and home photo albums are full of unconfirmed huge great white tales. And although few have been properly authenticated, there is a lot of circumstantial evidence to suggest that some great whites grow to more than 6 meters (20 feet) in length.

Top 15 Largest Birds in the World
Birds (Aves) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest bird species in the world (by body weight).
Birds form one of six basic animal groups, with the others being amphibians, fish, invertebrates, mammals and reptiles. They are endothermic vertebrates, characterized by feathers, toothless beaked jaws, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. They reproduce by laying of hard-shelled eggs (eggs fertilize inside the female). The fossil record indicates that birds are the last surviving group of dinosaurs. So, they are also termed avian dinosaurs.

Rainforests of the World (Infographic)
Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth. They cover only 6% of the Earth’s surface but yet they contain more than half of the world’s plant and animal species. According to the current estimates, around 40% to 75% of all biotic species are indigenous Notes 1 to the rainforests.
What’s more, there are probably millions of species of plants, insects, and microorganisms still undiscovered in tropical rainforests. They are responsible for 28% of the world’s oxygen turnover. More than 20% of the world’s oxygen is produced in the Amazon Rainforest only, that’s why it has been described as the “lungs of our planet”.
Unfortunately, rainforests are rapidly disappearing due to deforestation. The loss is huge, and probably hundreds or even thousands of undiscovered species going extinct every single day. We are losing them forever.

A cosmonaut’s view, just after launching a tiny satellite into the orbit
On August 15, 2018, two Russian cosmonauts aboard the International Space Station performed one of the longest spacewalks in the history of space exploration. During the spacewalk lasting 7 hours and 46 minutes, Expedition 56 Flight Engineers Sergey Prokopyev and Oleg Artemyev manually launched four small technology satellites and installed a German-led animal-tracking project named Icarus onto the Russian segment of the space station. Two of the satellites were only the size of tissue boxes.

We have an ethical obligation to relieve individual animal suffering
Last winter, unforgettable video footage online showed a starving polar bear, struggling in its Arctic hunting grounds. Because of global warming, the ice was thin and the food supply was scarce. The video generated a wellspring of sympathy for the plight of this poor creature, and invigorated calls for stronger efforts to combat climate change – and rightly so.

Dinosaur-killer Asteroid Triggered a Global Warming which lasted 100,000 Years
Around 66 million years ago, an asteroid or comet at least 10 kilometers (6 miles) in diameter impacted a few miles from the present-day town of Chicxulub in Mexico (hence it is dubbed as the “Chicxulub impactor”), at around 64,000 kilometers per hour (40,000 mph). The impact has created a crater (Chicxulub crater) more than 180 km (110 miles) in diameter. But, what’s more, the energy of the impact (which is equivalent of about ten billion Hiroshima atom bombs) vaporized the rock which was rich in sulfur compounds, filling the air with a thick cloud of dust, similar to that created by a catastrophic volcanic eruption. This cloud blocked out the sun at least for a decade and caused a global, dark winter: even in the tropics the temperatures were barely above freezing, and the average global temperature was below 0°C (32°F). Before the impact, the average global temperature was around 26°C (47°F), so this means a huge drop. And the recovery time was more than 30 years! The dinosaurs which had dominated the Earth for more than 150 million years were used to living in a lush climate and were already in decline, so non-avian dinosaurs couldn’t survive after the last deadly blow.

Most species hold their geographic range if we limit global warming to 1.5°C, study says
If we limit global warming to 1.5°C rather than 2°C above the pre-industrial levels by the year 2100, the impacts of climate change would be much less dramatic, a new study says. According to the researchers, for vertebrates and plants, the number of species losing more than half their geographic range by 2100 will be halved when warming is limited to 1.5°C, compared with projected losses at 2°C. It would be even better for insects, the most diverse group of animals on Earth: the number is reduced by two-thirds.
