Methods for increasing food supply include: ### Genetically modified crops ![Genetically modified crops](https://image-v2.cdn.app.senecalearning.com/2018-05/adca6aba-622b-430a-aa3e-60217659da23/shutterstock_755773648.jpg) - We can produce GM crops that grow faster, are resistant to pests, have higher yields and greater nutritional values. ### Reducing meat consumption ![Reducing meat consumption](https://image-v2.cdn.app.senecalearning.com/2018-05/39f1e592-9249-46d1-924a-64cf22a2c1ce/shutterstock_439196368.jpg) - Reared animals eat our crops. - If we eat those crops and cut out the middle man (animal), less energy will be wasted. ### Cutting down on food waste ![Cutting down on food waste](https://image-v2.cdn.app.senecalearning.com/2018-05/57837ffe-08e2-407f-aa69-abc9cf805e63/shutterstock_572389627.jpg) - The less food we waste, the more we can eat. ### Sustainable techniques ![Sustainable techniques](https://image-v2.cdn.app.senecalearning.com/2018-05/328af3a4-8f27-4e76-ba50-fc5863095b1b/shutterstock_766946728.jpg) - By using sustainable methods, e.g. sustainable fishing, to make sure we're looking after the environment and preserving resources, we can make sure that future generations can grow sufficient amounts of food. ## Fairtrade The Fairtrade Foundation aims to promote workers' and farmers' welfares in less developed countries as well as the sustainable production of food. ### Fairtrade's work ![Fairtrade's work](https://image-v2.cdn.app.senecalearning.com/2018-03/ae0f9c32-86ec-4841-a887-a1f68edf77b8/shutterstock_524456035.jpg) - A lot of the expensive products we consume (e.g. cocoa beans) rely on raw ingredients farmed in less developed regions. The farmers that produce these ingredients often get paid very little. - Fairtrade makes sure that farmers are paid a fair wage and works to improve their working environments. ### Impact ![Impact](https://image-v2.cdn.app.senecalearning.com/2018-05/4edb3be7-a450-475f-b3e9-70e0c7f3266c/shutterstock_471758339.jpg) - Fairtrade helps farmers to gain food security. - Once they start to get paid more for their produce, they can afford to spend more on food. ### Labels on foods ![Labels on foods](https://image-v2.cdn.app.senecalearning.com/2018-05/81cfc4ce-c0b3-44d6-945c-6bba0404fe71/shutterstock_552195223.jpg) - Fairtrade foods are labelled with the fairtrade logo. ## Test yourself on Sustainability of Food 2 - What is it called when people can access sufficient amounts of nutritious food to lead an active and healthy lifestyle? - What are the aims of the Fairtrade Foundation? - What foundation aims to promote workers' and farmers' welfares in less developed countries as well as the sustainable production of food? - How does the Fairtrade Foundation help farmers? - How do we know if food products are Fairtrade products?
