Electricity
Energy is everywhere. We use energy to move the mouse for a computer, to jump and shout and walk and run. It takes energy to power a light bulb, and the light that the bulb gives off is also a form of energy called radiant energy. Radiant energy from the sun enables vegetables, plants, trees and us to live and grow! Other forms of energy include heat, chemical energy, kinetic (motion) energy, gravitational energy and nuclear power.
Electricity is a form of energy and this is what powers the TV, the kettle, dishwasher, hairdryer, toaster, remote control, mobile phone, fridge, stereo, electric toothbrush, mp3 player and more!
Detectives - Can you guess how many things need electricity in your house? Take a guess, then go on a detective mission and write down all the things you find. Set up a competition in your family and see who's guess is the closest!
Our growing need for energy is one of the problems facing the world today, because producing electricity also produces our next topic - pollution. We also have some cool downloads, here’s two - Energy and Alternative Energy.
How to help
When you’re using electricity think about where it comes from and how you can use less to take the strain off of the environment - here are some simple ways to make a big difference:
•On or Off? Leaving televisions, stereos and computers on standby with the little red light showing still uses up electricity, even though they might look like they're turned off. To stop this you can turn them off at the wall. Simple!
•Lights out! Turning lights off when you're not in the room (make sure no-one else is too!) can save a lot of energy.
•Putting the kettle on Britons drink an amazing 60.2 billion cups of tea a day according to The Tea Council. That's a lot of tea, and a lot of electricity too! That's why it's important to only boil as much water as you need in your kettle. It's best to boil enough water for one cup, not three or five - plus you won't have to wait as long, which is a bonus!
•Brrrr The fridge is an important part of the kitchen, it keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so help it by not leaving the fridge door open or putting hot things inside.
•Shopping Many products are now helping you to reduce your energy use and your parents’ energy bills! Check new products for their efficiency grade and rating and keep an eye out for the Energy Efficiency Recommended logo.
•Harness the sun’s energy - An increasing number of people are fitting solar panels to their houses. Photovoltaic (PV) solar panels create electricity from sunlight, which can then be used to power their homes. Solar heating panels make hot water, reducing the need for electricity or gas to heat water or run the central heating system.

Pollution
Pollution is caused when harmful or poisonous substances are released or found in the air, rivers, seas, animals, plants or even our bodies. Now, we live on a strong planet with robust plants and hardy animals and humans - but there’s only so much we can take.
Did you know? Pollution is one of the main causes of asthma, which affects a whopping 1.1million children in the UK
Unless we are using renewable energy sources such as solar panels or wind turbines, producing the electricity that powers our homes and gadgets causes pollution. Some of the petrol or diesel that we put into our cars turns into pollution, which is contained in exhaust fumes. Diesel fumes contain particulates - a fine dust, which is not good for asthmatics, for example.
“What about cow farts?” I hear you ask. Actually, I didn’t hear and you probably weren’t asking that but yep, that’s right - we can’t leave out the massive impact of farming. The livestock we rear for meat emit more greenhouse gas than all the world’s transport! The greenhouse gas that livestock produce is called methane. Methane, together with other greenhouse gases like carbon dioxide contribute to global warming by acting like a blanket surrounding the whole planet, trapping the sun’s heat within the atmosphere and causing global temperatures to rise.
Chemical waste from factories and sewage works can also cause pollution that can get into our rivers and seas, which soon carry the harmful particles for miles. Litter is considered pollution as it can cause harm to wildlife and disrupt rivers, streams, seas and other habitats. Harmful chemicals can also be found in many household and garden items, from plastics to cleaning products, weedkillers and sprays.
But all is not lost. We can all learn a few little tips to help protect the environment and its future:
How to help:
•Don’t drop litter Birds and animals can mistake litter for food. Litter can end up in rivers and block drains, or in the sea and be eaten by fish. Also, some litter will stay around for thousands of years!
•Save it! All of the electricity saving tips in the above section will also help reduce pollution.
•On your bike Instead of taking the car get your bicycle out or take the ‘shoelace express’ - also known as walking.
•Pleasing products Many household cleaning products contain harmful chemicals which are washed down the drain. Encourage your parents to buy eco-friendly products or even make your own from natural substances like vinegar and lemon juice.
•Detectives If you spot pollution, such as oil on the beach, report it to the local council. If you suspect a stream is polluted, report it to the Environment Agency.
There’s a lot more to know about pollution and knowing more will help you do more to protect the environment. For more information see these factsheets - Pollution, Sea Pollution, River Pollution, Ozone Layer, Global Warming.

Food
We can’t live without it! With more than 7 billion people on earth the demand for food has never been bigger. In the UK alone we spend about £182 billion pounds a year keeping fed and watered. That’s a lot of food!
The first question is - where is all this food coming from? Our food comes from all over the world - your green beans might come from Egypt, coffee maybe from Africa, perhaps your bananas have travelled from Ecuador and apples flew across the Pacific Ocean from New Zealand. All of these ‘food miles’ amounts to a lot of transport and transport means fuel and fuel means pollution.
What else does food need to grow? Water and good soil! Plants and trees that give us fruit need to eat too you know. Some countries and farms add pesticides and insecticides to food to keep away pests and insects. These chemicals can sometimes be harmful to wildlife and their habitats and sometimes to humans too. Look at ‘How to help’ to find out more.
Here in the west we eat 7 times more than people in poorer countries. And one thing we eat a lot of is meat and dairy food. What do these foods have in common? Meat and dairy food both come from animals, and animals also need food and water. And as we saw above, they also fart a lot! Livestock farts produce a greenhouse gas called methane and all this amounts to 20% of the world’s climate-changing gases. Phwoar! A suggested alternative to meat is insects - Insect Burger anyone?
How to Help:
•Reduce your mileage eating food and drinking drinks produced in the UK reduces the carbon footprint of your diet. This means that you are helping to reduce pollution! Look at the for little red tractor on products in your supermarket.
•Meat Free Mondays are an easy and effective way to cut down on meat. Make one or even two of your days meat-free.
•Eat organic organic foods have had no insecticides and pesticides added to them which makes them that bit more natural and healthy. Eating organic food reduces how many chemicals are made and spread across the countryside.
•Get worms! Food waste is an important issue as 7 billion of us munch our way through millions of tonnes of food. Give your leftovers to worms in your very own wormery and they’ll turn it into rich and healthy compost for your vegetable garden and flowers!
•Washing Always wash your hands before eating to prevent the spread of invisible bad stuff like bacteria and chemicals. It’s also good to wash fruit and vegetables before eating or cooking.

Water
Turn on the tap and there it is. Getting water is so easy that you’d be mistaken for thinking that there was an endless supply. But the world has a water shortage. 70% of the world is covered in water - we should call our planet ‘ocean’ not ‘earth’! But most of this water is salt water, leaving only a small percentage of fresh drinking water. Countries including Spain, Italy, Peru, China and South Africa actually import water from exporting countries such as the US, Australia and Argentina. A staggering 1.1 billion people on earth have no access to clean drinking water. This global shortage is predicted to get worse as global temperatures rise.
Every person in the UK uses about 150 litre
