Will the Sixth Mass Extinction Event Happen on Our Watch?
The very first life on Earth evolved over 3 billion years ago. Since then there have been five mass extinction events, the last of which killed off the dinosaurs. Some scientists now believe that we are on the verge of a sixth event. But what causes these mass extinctions and what can we do?

The Adventures of Cha-Cha the Dragon – Part 1
A chapter story by Iona…
Once upon a time, in ancient China, there lived a wise and mighty dragon. His name was Cha-Cha. He being a magical dragon, he had many enemies. Among these were an ancient race, whom battles with Cha-Cha had all but killed off.
Only one remained. He was the great ”Earth Traveller” or E.T. for short. E.T. could take many forms, including a long pink one that he had to fill in for the birth of his 100th son.Other than these he could take the forms of fearsome animals, such as a tiger, a snake or a badger.
How to Stay Safe at the Beach
Although beaches are fun places they can also be dangerous, and you may have heard some stories in the news lately about people getting into difficulties when they’re in or by the sea. Our science editor Sam Gouldson, who lives on the Sussex coast, shares her tips for beach safety.
Go to a Beach with Lifeguards
Many beaches have lifeguards, who are trained to keep people safe whether they’re on the beach or in the sea. You can find out where these beaches are by searching the Good Beach Guide (for the UK), Irish Water Safety (for Ireland) or the ILSE (for Europe). Find out more about the RNLI Lifeguards in UK here.
Pay Attention to the Flags
Beaches in the UK use a flag system to inform you of possible hazards. If there are red and yellow flags this means that there are lifeguards in that area and that it’s safe to swim.
A black and white chequered flag means that the area is for people using paddleboards, surfboards and kayaks, and that you should not swim there.
A red flag means that the area is dangerous and you should not go into the water for any reason. There may also be information boards and signs at the beach, and you should read these thoroughly.
Stay With Your Group
If you stick with your family or friends you can all keep an eye on each other. Find somewhere distinctive to use as a base while you’re at the beach and agree where you’ll meet up if you get separated.
If there are younger children in your group make sure they’re with a responsible adult or older teen. Some beaches have a wristband scheme so that children can be easily identified and their group members contacted if they wander off; if the beach you’re visiting has one of these schemes, take part.
Learn About the Sea
Different beaches have different conditions. The tide can come in much faster at one beach than at another, and you should always keep an eye on the water and which direction it’s flowing in. You can look up tide tables online so that you’re aware of when the tide is likely to turn and don’t get cut off from the shore.
Some beaches have dangerous features called rip tides, which are strong currents that can quickly sweep you out to sea without warning. Always check with the beach’s lifeguards if there are any areas that you should avoid – many beaches have a noticeboard to inform visitors about the current conditions.
Waves can also be dangerous, depending on how fast the water is moving and how steeply the beach shelves. Some beaches will have sharp rocks or other hazards that may not be clearly visible from the shore. Again, check the lifeguard’s advice before you go into the water.
If the weather is cool, consider wearing a protective suit to keep you warm in the water, as cold water shock can affect your breathing, blood pressure and heart rate.
Be Careful When Using Inflatables
Inflatable toys and beds are designed to be used in swimming pools, not on open water. But if you do use them make sure there is an adult with you and that you’re in the lifeguarded area between the red and yellow flags.
You should stay near the shore and never use inflatables when there are big waves or an windsock is flying; these are signs that the wind is too strong.
Know What to Do If You Get Into Trouble
If you find yourself in difficulties, stay calm. If the water is shallow enough for you to stand, wade through the water instead of trying to swim in it. Raise at least one hand in the air and shout loudly and clearly for help, and don’t try to swim against the tide because you’ll just tire yourself out.
If you have a board or an inflatable hold onto it; not only will it help you stay afloat it will also make you easier for rescuers to spot.
If you see someone who is in trouble in the water, stay calm. Alert the lifeguards, or if you can’t see them call the emergency services on 999 (in the UK) or 112 (anywhere in Europe).
Stay Safe in the Sun
Although the sea can be dangerous, so too can the sun. Always use sunscreen with a sun protection factor (SPF) of at least 30, and re-apply frequently.
Keep your head and shoulders covered, wear sunglasses to protect your eyes and stay in the shade at the hottest part of the day (usually between 11am and 3pm).

Stories From The Stables – Sam

I fell off, honest
Learning to ride is a fabulous hobby. It can be pricey, but you can borrow a hat and crop from most stables, and start off in trousers and strong shoes. It is great exercise, very exciting, and teaches respect for animals, balance, and correct posture.
When I was very young I rode at Stourton Stables, a children’s riding school where the ponies were mostly grumpy and had to be separated in the fields for fear of kicking each other to pieces.
Oh, happy riding lesson days. Hours spent in icy pouring rain, in snow, in fog, and even more rarely; in lovely sunshine. The best riding times of year for me were spring and autumn, before and after the major insect season.
