An example of what the PYP Exhibition can be like.

In the world there are many problems like debt or poverty and this problem is about the wastage of food and water. 8.3 tonnes of food is wasted every year in the U.K. 100 billion of pounds are wasted every year in the US. 52,650 gallons of water are wasted per year. That’s a lot food and water; imagine you saw that pile in front of you might miss the sun.

Food

Food waste is left over food from people or animals. It’s really bad for the poor because the poor won’t have any thing to eat and they will starve till death. People don’t finish their food because they are too full to eat the remaining food on their plate. This is a big issue because other people will won’t have enough food. In a rich country like the United States of America there is lots of food so some people in the US don’t even care that they are wasting their food. If you want to reduce food wastage in restaurants you can to make reservations. For guests, they can get a little bit each time they get food for themselves

Water

Water waste is left over water that people get or use too much. If the poor don’t have enough water they will die because if you don’t have a drink for 3 days you will die. People waste water by over watering the plant, they leave the tap on or they are too lazy and just throw away their water. People can use wasted water and turn it drinking water by just clean it. Sometimes when people waste water they aren’t even realizing it like when they wash the dishes. Water pollution is also water wastage because if poor people don’t have water the only way is to drink river water but they would rather drink a clean river more than a polluted river. But the better way is to donate water to the poor. In case you didn’t know, wasted water can be reused as drinking water if it goes through a water treatment plant. Don’t waste it because it is the most important element on Earth. In the US on average, each person uses more than 50 gallons (more than 190 litres) of water per day.

Student Q&A for PYP.E (our Project) For our project we needed to think of some Q&A thing about our real –life issue and here are the Q&A of my most important questions.

Question: Organic waste isn’t so nice at being ‘clean’ to look at but is it a good fertilizer?

Answer: Yes, there are many ways and ingredients to different fertilizers. For compost there are different varieties and for one the ingredients are basically fruit skin and scraps of dirt and manure. This is a great way of turning leftover food into fertile dirt is a great way of reusing the wasted food. A school system in Korea is that there are different types of trash cans where there are glass trash cans, plastic trash cans and food trash cans. One person comes around collecting the food scraps and grinds the leftovers and turned it into animal feed. In Thailand composting for some 400 farmers is a way to let their crops grow faster and better. While others wait for years to let their food grow these farmers know the technique with the back of their hands. It takes 30 days or about one month to let the plants grow their productive vegetables. Although they need special tools to complete their task they complete their goal. First A 38 centimeters squirrel-cage blower with 2.2 kilowatts motor is used to force air through 10 covered static piles of compost twice a day. The raw materials that are used for the compost is agricultural wastes and animal manure in the ratio of 3:1 by volume not the sound volume. Sustained, high temperatures can destroy insects, larvae, and weed seeds, but no compost will be completely sterilized by high temperatures alone. In hot compost where the temperature is kept at 55 °C for several weeks, the strength that has most organisms to survive is of course agreed. Nevertheless, many organisms in nature can survive extreme temperatures, including extremophiles such as Thermos thermopiles which play an important role in thermogenic composting, as well as pathogens such as Clostridium. The necessary second stage of any composting is maturation, a period allowing the dissipation of readily available substrates for pathogen proliferation and any phyto-toxins remaining from the process or contaminating ingredients and achieving a state of nutrient stability that will not have an impact on Nitrogen availability in the receiving soil. It is a popular - and dangerous- misnomer of the composting industry that once a pile gets hot for a short period of time, pathogen content is eliminated. This is what the farmers do to terminate the bacteria.
