Astrobotanists have managed to grow seedling from lunar "soil"...what other elements of biology could we use to help man travel to the moon and beyond?

These are the first plants grown in moon dirt The first attempt to grow plants in Apollo samples from the moon shows the promise and potential struggles of farming in lunar soil.

Best of luck to all students sitting for their biology O'level examination today and tomorrow!

Great news! The ozone layer is on track to heal completely! 🌍 However, we can’t help but wonder what else we can accomplish in our fight against climate change if we really put our minds to it 💪🏽

In the 1970s, atmospheric scientists noticed the thickness of the ozone layer in the upper atmosphere, the layer of gas that deflects much of the sun’s radiation, had started thinning. The primary culprit was chlorofluorocarbons (CFCs), a chemical compound present in everything from aerosol cans to refrigerators to solvents. By the mid-1980s, it was on track to be wiped out in the next few decades. Fast-forward to today: The ozone is on the path to recovery. Experts estimate that by 2050, it will be back to the state it was in the 1980s.⁠
⁠
When the ozone layer suddenly started to hurtle toward disaster, the world responded — with consumer boycotts, political action, a major international treaty called the Montreal Protocol, and a huge investment in new technologies that allowed for a rapid phaseout of CFCs. The efforts effectively halted new CFC production by the 1990s and early 2000s, and CFC emissions have been steadily falling since the treaty went into effect in 1989. ⁠
⁠
The chemicals that replaced CFCs are called hydrofluorocarbons (HFCs), which are less dangerous to the ozone layer. But they’re still potent greenhouse gases — thousands of times more powerful than carbon dioxide at trapping heat in our atmosphere. Twenty years ago, they were seen as an environmental step forward. Today, phasing them out is seen as a critical step to head off the worst of climate change. Earlier this year, the United States belatedly signed the 2016 Kigali Amendment, which extends the Montreal Protocol to almost entirely phase out HFCs over the next 30 years — 197 countries have adopted the agreement.⁠
⁠
The worldwide effort to heal the ozone layer reveals that while human ingenuity can solve our problems, it can also create new ones as it does. The campaign to phase out CFCs was a huge success. Even with the complications and caveats, it should be seen as an instructive success story — one that can perhaps inform our response to the climate crisis.

An interesting and concerning discovery!

Microplastics found in human blood for first time after scientists make 'concerning finding' Scientists have warned the long-term consequences of microplastics being found in the bodies of humans 'are not yet known'.

On the 3rd of March, the UN celebrates World Wildlife Day.

"World Wildlife Day is an opportunity to celebrate the many beautiful and varied forms of wild fauna and flora and to raise awareness of the multitude of benefits that their conservation provides to people. At the same time, the Day reminds us of the urgent need to step up the fight against wildlife crime and human-induced reduction of species, which have wide-ranging economic, environmental and social impacts. Given these various negative effects, Sustainable Development Goal 15 focuses on halting biodiversity loss."

Earth's Water Cycle Is Changing Dramatically, And Much Faster Than We Predicted Fresh water cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give us the illusion of certainty. Fresh water will always come from the tap. Won't it?
