Our activity is focus on presenting the main problems of sustainability. We identify four directions of action (water, food and energy waste and recycling) and we develop science experiments in order to raise the involvement of young generation in solving them.
We also have offered simple actions, easy to take, in order to solve parts of these major problems.
1) We shall start with water in general and water waste in particular. Water is a vital component for us. As for that matter, we shall protect it at all costs. The best way to improve surface water quality is to prevent pollution at its source! Here are a few tips on preventing water pollution:
- When you brush your teeth, don`t let the water run;
- Take short showers;
- Use dishwashers;
- Avoid losses;
- Collect the rain water;
- Sprinkle the garden abstinent;
- Boil only the required amount of water.
2) Food waste is another subject at interest and we present another tips on preventing its waste.
- Pre-plan and write your shopping list before going to the grocery store. As you write your list, think about what meals you will be preparing the following week, and check your fridge to see what items you already have.
- If available, purchase “ugly” fruits or vegetables that often get left behind at the grocery store but are safe to eat. “Ugly” produce has physical imperfections but are not damaged or rotten. “Ugly” fruits and vegetables are safe and nutritious and can sometimes be found at discounted prices.
- When eating out, ask for smaller portions to prevent plate waste and keep you from overeating. You can also request a take-away box to take leftovers home instead of leaving food on your plate.
- Refrigerate peeled or cut veggies for freshness and to keep them from going bad.
- Use your freezer! Freezing is a great way to store most foods to keep them from going bad until you are ready to eat them. Create a designated space in your fridge for foods that you think will be going bad within a few days.
- Learn about food product dating. Many consumers misunderstand the purpose and meaning of the date labels that often appear on packaged foods.
- Use “ugly” fruits or vegetables to whip up healthy smoothies and soups for your friends or family. No one will notice the difference!
- Be creative and have fun! Create new dishes and snacks with leftovers or items you think will go bad if not eaten soon. Have a cook off to find out who can come up with the best dish
3) Everyone knows about energy but a few knows about the necessity of using it with responsibility. Our ideas for preventing the energy waste are:
- Turn off the lights
Just one switch and you’re done!
- Shutdown your computer
Computers are some of the biggest energy users. Turn your monitor off at night and ditch the screensaver. So power down!
- Use cold water instead hot water
Use cold water to wash fruits and vegetables. Using less hot water will save the energy needed to heat the water.
- Use reusable materials
Place household waste in reusable containers.
- Be smart
Decide what to take from the fridge before you open it.
- Use towels made of textiles instead of paper towels when wiping your wet hands. Not only do many trees are cut down, but energy is also consumed to process wood.
4) Recycling and the 3R rule (Reduce, Reuse and Recycle) is the secret of sustainable development. It seems to be important to know that:
- One liter of oil that you used for cooking and that you do not throw in the sink, means preventing a possible pollution of 1 million liters of water.
- By recycling a ton of paper, you save 17 mature trees that produce the oxygen needed by 900 people every hour.
- By recycling a single bottle, which once taken to the landfill will take hundreds of years to degrade, enough energy is saved to keep a 15 Watt light bulb on for 24 hours.
- Expanded polystyrene, also known as “scratchers”, is used to cover various items when we buy them from the store. Unfortunately, this material is not easy to recycle and when discarded, fill the areas around the city
