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.

Bananas have died out once before – don’t let it happen again
![A banana is an edible fruit - botanically a berry - produced by several kinds of large herbaceous flowering plants in the genus Musa.[3] In some countries, bananas used for cooking may be called plantains, distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow in clusters hanging from the top of the plant. Almost all modern edible parthenocarpic (seedless) bananas come from two wild species - Musa acuminata and Musa balbisiana.](https://ourplnt.com/wp-content/uploads/2018/06/Bananas.jpg)
You probably take bananas for granted. In the United Kingdom, one in four pieces of fruit consumed is a banana and, on average, each Briton eats 10 kg of bananas per year; in the United States, that’s 12 kg, or up to 100 bananas. When I ask people, most seem to think bananas grow on …

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 …
Earth’s Biosphere from space, “The Green Marble”
NASA has published a video titled “Earth’s Biosphere: The Green Marble”, showing the monthly averages of land greenness (vegetation) and ocean chlorophyll. You can watch how the primary producers (plants and phytoplankton) transform the Earth’s landmasses and oceans over 12 months.
What did Ancient Earth Look Like
I stumbled upon an amazing web page showing what did ancient Earth look like. On the “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient …
Iceland is growing new forests for the first time in 1,000 years
Iceland was extensively forested when it was first settled. When the Vikings first arrived in the 9th century, the Nordic island was covered in 25 to 40 percent forest, compared to 1% in the present day. In the late 12th century, Ari the Wise (Ari Thorgilsson, 1067-1148 AD), Iceland’s most prominent medieval chronicler, described it …

Unfortunately, things do not always happen the way we would have wanted. Here are 10 recently lost natural wonders that have been disappeared in recent centuries or even …
