Did you know? A snail can sleep up to three years. Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as 'summer sleep'), helping to escape warm climates. Butterflies taste with their feet. Butterflies taste food with their feet. Butterflies have taste sensors on their feet and by standing on a leaf, they can taste it to see if their caterpillars can eat it. The flying insects mainly consume liquids like nectar or juice from fruits, and sometimes even fluids from carcasses. Most lipsticks contain fish scales. Lipstick contains fish scales.

Rolls-Royce was acquired by the British Conglomerate Vickers in 1980 and then purchased by BMW in 1998. BMW built a new, dedicated Rolls-Royce factory in Goodwood, England. The plant itself was designed to be energy efficient, eco-friendly and benefit manufacturing at the same time. The Phantom was introduced in 2003 as the first incarnation of the new generation of Rolls-Royce motorcars. It comes in 44,000 colours.

Earth Day 2022 #InvestInOurPlanet

Image
Earth Day , celebrated annually on April 22 , is a reminder to protect the environment, restore damaged ecosystems and live a more sustainable life. The event was first celebrated in 1970, making this year the 52nd anniversary of annual celebrations. Earth Day was first observed in the United States, when some 20 million people took to the streets to protest against the 1969 Santa Barbara oil spill. Since then, the occasion has played an important role in raising awareness on other environmental issues. This year, earthday.org has selected the theme, ‘ Invest In Our Planet ’. It explains, “This is the moment to change it all — the business climate, the political climate, and how we take action on climate. Now is the time for the unstoppable courage to preserve and protect our health, our families, our livelihoods… together, we must ‘Invest In Our Planet’.” Today, Google's annual Earth Day Doodle addresses one of the most pressing topics of our time: climate change .
