ocean

The ocean—the seas—are made up of 96.5 percent pure water. The remaining 3.5 percent is made up of 75 other elements. Six elements are responsible for 99 percent of the sea’s saltiness. They are: chloride, sodium, sulfur, magnesium, calcium, and potassium. Most of the saltiness comes from the compound sodium chloride (ordinary table salt).
Where do the elements come from? The wearing away of rocks on land. As rock erodes, rivers carry the salts and other minerals to the ocean. Volcanoes and undersea springs also release salts to the ocean.

• Some parts of the ocean are saltier than others. Hudson Bay has lower levels because of fresh water entering the ocean from lots of rivers and melting ice.

knysna swap shop
recycling waste

ECO-FRIENDLY ... A group of school pupils bring their recyclables to the Swop Shop at Sinethemba in Knysna in exchange for basic items like toiletries and stationery.

A RUBBISH-SWOPPING initiative has been launched in Knysna’s Concordia area where children can exchange recyclable refuse for basic items such as food, toiletries and stationery.

A similar programme that has been running in Hermanus for seven years was adapted by Sue Swain, the bio-mimicry facilitator spearheading the municipality’s “Knysna Turns to Nature” campaign, Edge of Africa, the Knysna Economic Development Agency (Keda) and Knysna Tourism.

“The Swop Shop programme basically entails children collecting recyclables and bringing it to one of three Swop Shops where the waste will be weighed. Based on the weight collected, children will earn Edge tokens which may be redeemed at the shop for items such as basic toiletries, stationery, clothing, pet food or toys,” Swain said.

She said the waste would then be sorted and taken to a recycling centre in Concordia.

“We would also like to get adults involved with this programme. Over 18s will earn Edge tokens which may be exchanged for a variety of empowerment courses such as literacy, computer literacy and welding,” Keda representative Teres Goslett said.

The Swop Shop project relies heavily on donations from the public to stock the shop and Goslett said goods such as basic toiletries, stationery, non-battery operated toys and pet food could be delivered at the Keda Office in Woodmill Lane on weekdays.

Edge of Africa co-founder Dayne Davey said they were still looking for funding for three shipping containers to be used as shops but the sites had already been identified.

“It will be run as a mobile facility for now and children will be able to swop and shop at Sinethemba, Magdaleentjie’s Creche and the BMW Love Life Centre on different afternoons of the week,” she said.

She said the project would not only contribute to a cleaner environment, but would provide children with the opportunity to be rewarded for their recycling efforts while meeting their basic needs.

“It will teach them the value of saving, as well as promote the learning of basic mathematical skills as the children will be involved with the weighing and calculations.

“Once this pilot project is up and running, the understanding of the impact of waste may be extended to the pricing of goods according to their carbon footprint,” she said.

She said children would also be helped to assess and understand the life cycles of products.

“This has become an essential practice in the commercial world as products are being increasingly judged on their impact on the environment.”

Swain said the pilot project was identified bearing in mind the basic principle that waste is a valuable resource in the natural world.

“Biomimicry asks us to look at the natural world to find better ways of conducting our day-to-day business. The natural world has been engineering, constructing, manufacturing and producing for billions of years without tapping into fossil fuels or producing harmful waste. All waste produced in nature is useful, either serving as food or as a resource for the next creature.”

going green

Are you itching to go green – to do your bit for the environment – but so overwhelmed by the concepts of carbon footprints, self-sustainable, and eco-friendly that you don’t know where to start? We’ve compiled a list of ten simple things that you can do to go green and reduce your impact on our beautiful earth.

1. Walk!

South African’s are hugely reliant on their cars to get from A to B but our obsession with our cars often goes far beyond necessity. We live in a beautiful country so why not enjoy it. If the place you are going is five minutes away relish the exercise and the fresh air you will get and the amount of petrol you will save from taking a stroll every now-and-then.

Green apple2. Re-use, re-use, re-use

Whenever possible try to buy second hand or used items. Instead of splashing out on a new car why not buy a reliable used car from the previous year? Humans are quick to dispose of perfectly suitable items in favour a new one. This obsession with discarding items which are in perfect working order is wasting valuable resources the world over. And if it isn’t in working order why not try to have it fixed before chucking it out? Many items can be restored and made as good as new with a little bit of TLC. Also, give things away if you have no use for them anymore. Donate unwanted clothes and household items to charity shops or friends.

3. Local is better

Next time you are in the grocery store examine the labels of items to find products that are locally produced. These products use fewer resources to get to you and also help boost the economy. So if it’s available locally why spring for the proudly SA products instead.

4. Turn down the heat

Resist the temptation to turn up your household heating system in the cold. Use heaters to warm up a room and keep heat in by drawing the curtains and closing windows and doors. Whenever possible wrap yourself up in warm blanket and clothing instead of turning on a heater. Or, if you have a fireplace, light a fire and snuggle up in front of the fireplace. Use energy efficient heating like heated blankets, gas heaters, and wall heaters as these use less energy than conventional bar heaters.

5. Cut back on bottled water

South Africa is known for the quality of its drinking water so why not drink our natural H2O instead of buying the bottled stuff – which, in most cases, is nothing more than factory treated water. If you are addicted to your Adam’s Ale buy a swanky water bottle and keep it topped up with tap water. If you feel that you need more purification invest in a water purifier and drink with peace of mind.

6. Have a green thumb

Beautify your garden and plant a tree or two – or 5 – you will be doing your bit for the earth and your garden will look green and lush. If live in an apartment and don’t have a garden find some great clay pots and plant small tress in these to place on your balcony or in your lounge. Your home will look more welcoming with a plant or two.

7. Reduce your Vampire Power

Vampire power refers to the power consumed by electronic appliances whilego green lightbulb

they are switched off or in standby mode. Fifteen percent of your electricity is wasted on those beady-eyed little red lights that let you know your appliances are on standby mode. Although the power needed for standby mode is relatively small, because these are continuously plugged in the usage eventually adds up. We are all guilty of leaving our cell-phone chargers plugged into the socket and out TVs on standby all night long. Turn devices off at the wall while they aren’t in use to save on unnecessary electricity costs.

8. Recycle glass

Glass takes about one million years to fully decompose and why waste such a sturdy substance which can be used again and again in your home. Take glass soft drink bottles back to your local cafe – if the deposit isn’t of consequence to you put it in the nearest donation tin at the till point – re-use glass jars for nails, and bits-and-bobs at home; and recycle any glass items you can’t find a use for.

9. Get rid of junk mail

Spend some time de-registering from junk mail you applied for – or didn’t apply for – ages ago. If you can’t find the time to do this there are services which help you get rid of the copious amounts of junk mail you receive by opting out on your behalf. This small effort will lead to a lot less tress being chopped down to take up room in your mailbox.

10. Go online

Once you’ve rid your mail box of junk mail stop wasting paper by having your bills mailed to you every month. Instead, where possible, have your bank statement, bills, and other mail emailed to you. Pay your bills online and save time and millions of tress in the process.

We at www.waterandsolar.co.za want South Africa to start seriously looking now at renewable energy and reduce its need for coal fired power stations.  As individuals we can start in our homes by following the 10 steps above and by switching to solar water heaters, introducing a greener way of living with greywater systems and rainwater harvesting.  Together we can start reducing our homes carbon footprint and our need for coal hungry Eskom.

EnviroKids quiz
Glenwood House learners answering the questions: Isabella Rodgers, Mignon Bettings, Monhe van der Watt and Denise Robertson.

GEORGE NEWS – This year’s EnviroKids quiz was held at the Moriarty Environmental Centre at the Garden Route Botanical Garden, in celebration of the International Year of Biodiversity.

This exciting project involved Grade 7 learners from Glenwood House, Holy Cross Primary School and Outeniqua Primary School. Each school was represented by a team of 10 learners.

The quiz is a fun way to bring learners from different schools together, and uses the popular WESSA magazine, EnviroKids, as the basis for the questionnaire. A group of four learners from each team answered the questionnaires which involved biodiversity, climate change and Arbor Week themes. The rest of each team made up the audience.
The learners had 30 seconds to each draw something from a forest ecosystem, which caused much laughter, shouts of encouragement and good natured arguing.

With the seriousness of climate change and what is currently happening to our weather patterns, the day was concluded with an activity on what can be done to lessen our carbon footprints. The learners came up with creative ways of expressing their ideas. Glenwood House gave many ideas for taking action to better our environment, Holy Cross addressed the problem of littering with a short act, and Outeniqua Primary entertained with a fantastic song and dance routine.
