Sustainable Development is the development we do now in the present, making sure that it does not affect future generations to realise their needs. That is developing an environment for future generations to live sustainably without compromising their needs.
The critical concerns in South Africa are food security and malnutrition especially in women and children. This is also not addressed in the basic education curriculum of life skills. Teacher educators should include these aspects so that teachers will be able to pass this to learners in class and do practical work (e.g. vegetable gardens) which help in understanding SDG 2 and 3. This will introduce the aspect of sustainability in learners thus empowering them to make decisions and responsible actions in producing their own food to fight food insecurity and improve nutrition.
