Planetary management is a way of taking care of the planet we live on. It helps us make sure that we are taking good care of the Earth and its resources, so that we can all have good health and a happy life. To do this, we need to make sure that we use things wisely and don't waste them, like energy, water, and food. We also need to make sure that we don't hurt nature or pollute the air, land, or water. Finally, we need to work together to help protect animals and plants so that they can have a safe place to live and can stay healthy.
