Building the #ZeroHunger Generation

Preserve the earth’s precious natural resources

The earth provides us with everything we need to grow food and live healthy lives, in the form of natural resources. These resources are land, water, animals and plants. We can’t grow food without water and soil, and we will have a much harder time growing enough healthy and nutritious food if the water we have is polluted and the soil has been stripped of all the rich minerals that make it fertile. If we want to be able to continue to grow enough safe and nutritious food for everyone on the planet we have to protect our natural resources. 

Don’t waste water

Don’t waste water

Take a short shower rather than a bath. Bathtubs use gallons more water than a 5-10 minute shower. And turn off the water while brushing your teeth. Cleaning your teeth with the tap running uses 6 litres of water, while cleaning them with the tap off uses less than 1 litre of water. Remind your parents to fix any leaks - a leaky tap can waste more than 11,000 litres of water in a year! The plants in your garden can also be watered with collected rainwater and ‘grey water’, which is the water you use to wash your hands and/or dirty dishes.

Eat new things

Eat new things

Try to eat an all-veggie meal (including pulses like lentils, beans, peas and chickpeas) instead of one meat meal a week. More natural resources are used to provide meat than plants or pulses, especially water. Millions of acres of rainforest are also slashed and burned in order to turn the land into grass pastures for livestock including cows.

Keep our oceans full of fish

Keep our oceans full of fish

Convince your friends and family to eat fish species that are more abundant, such as mackerel or herring, rather than those that are at risk of being overfished, like cod or tuna. You can also buy fish that has been caught or farmed sustainably, such as eco-labelled or certified fish, and if you order seafood at a restaurant, always ask if it’s sustainable.

Energy efficient is best

Energy efficient is best

If your family is thinking of replacing household appliances, like a fridge or a washing machine, you can recommend that they buy energy-efficient appliances, that use less electricity. Save energy also by turning off the lights when you leave a room, unplugging your TV, stereo or computer, rather than leaving them on standby, and by using energy efficient light bulbs. You could also put on an extra jumper in the winter and ask your parents to turn down the heating, or shade the windows from the sun in summertime.

Buy organic

Buy organic

Organic farming helps our soil to stay healthy and retain its ability to store carbon, which helps reduce climate change. Help your parents to find organic and fair-trade products in your local supermarkets or farmers’ markets. 

Keep soils and water clean

Keep soils and water clean

Pick up litter and ask your parents to choose household cleaners, paint and other products that are free from bleach or other strong chemicals. By reducing litter and using eco-friendly products we can limit water contamination and soil degradation. 

Use solar panels or other green energy systems

Use solar panels or other green energy systems

Find out if you can do so at home, school or at work by asking your teacher or parents to research available grants and government incentives.
