Bottled water is a matter of concern for many reasons. It takes more than 7 liters of water and 162g of oil to make plastic bottle. However if buying a bottled water is needed, try to support local brands that are using recycled plastic or that are investing to protect the environment like Life Water from Pembrokeshire or One Water which donates all its profit to provide clean water in the developing world.
However, the real alternative and eco beverage still remains tap water !

A billboard creating drinkable water out of thin air !?
You read it well; the UTEC (University of Engineering and Technology of Peru) and an advertising agency developed a billboard that produces around 100 liters of water a day from nothing more than humidity.
The billboard produced around 9,450 liters of water in three months, capturing air humidity. The production is equal to the water consumption of a hundreds of families per month. Strategically placed in the city or in outlying villages, it might do a big difference. Moreover, imagine what you could accomplish in any number of troubled spots around the world that need potable water with a solution like this one! Discover more about this amazing project and on how to make a difference and change the world.
Almost everyone knows that water is a limited resource, but we still continue to avoid the topic. Are we aware of how much water one person needs for drinking, cooking, or cleaning?
Here are some facts about water, that you maybe didn’t know:
A person needs about 20 – 50 litres a day for drinking, cooking and cleaning according to the UN.
We have only 1% fresh water on Earth, and all 7 BILLION people must share this 1% water.
The United States has the biggest Water Footprint (2483 m3/capita/year).
Everyday 132 litres water are used for Garden Hose/ Sprinkler, followed by 125 litres water for Power Shower (under 5 minutes).
128 litres water per year are wasted, if you have a dripping faucet (1 drop per minute).
To produce one kilo of rice – it takes 1000 – 3000 litres of water.
For 1 chicken – 44 litres of water are used.
A person taking a 5 minute shower in a developed country uses more water than a person living in a slum in a developing country uses in a day.
Americans use 5 times more water than Europeans do.
More people have a mobile phone than a toilet.
So there is one conclusion to make: Every Drop counts !
Dear USI Students,
as we are a big family, we wanted to give you ten tips on how to reduce your footprint.
- Join a Sustainable Student Organization or in our case just create a sustainable student organization (for serious considerations: please contact SINC).
- Study Sustainability: just attend a sustainable course or if you have any ideas of sustainable projects -> Let us know!!
- Conserve Electricity: If you happen to take a break of Facebook or Twitter, just shut down your laptop or if you live in a dorm, make sure to use LED lights.
- Reusable water bottles: One of our biggest enemies: PLASTIC. There are so many reasons, why you should not use plastic bottles anymore. There are only benefits at using reusable water bottles. Besides Mother Nature will be grateful for that.
- Second Hand Shops: Don´t be shy to enter in a Second Hand Shop, we are sure you will find something interesting. Macklemore has even wrote a song about Second Hand Shops
- Textbooks: Please don´t start a bonfire with your Textbooks, you can sell them to other students and earn some money.
- Remain Digital: If you really don´t like books, there is an option: Digital Textbooks. Of course there is also a benefit: Reduction of paper.
- Ditch the Car: At the main entrance of the University there are rental bikes, but if you happen to live far away, just take the bus or create a carpool.
- Buy Locally: We have to support local restaurants, farms etc
- Swap Party: Meet up for Swap Parties, just share clothes, DVD´s, books you don´t need.
