We all have different ways of supporting the environment in our daily lives, whether through habits big or small, and it can often be helpful to see what others are doing to care for nature. To be clear, this isn't a place to shame others into changing their habits, but to offer ideas and support for those who need it.
As a quick example of a tip for living in an eco-friendly way, composting can be a very helpful way of reducing greenhouse gas emissions. From what I understand, the energy involved with excavating a dump and compressing garbage into it (including food scraps) creates emissions, and biodegradable food waste sent to a dump releases methane. Composting is a good way to avoid this.
My family layers our kitchen scraps in a square of earth and leaves in our backyard, and it's been really cool to see how the compost has transformed the soil into a rich, living black, often with little green shoots popping out of it.
For anyone interested in learning more about composting, here are a couple of good resources on how to do it, what things you should and shouldn't add, and some of composting's benefits:
