Here are some tips for a green life:
Reduce
Try to reduce your consumption of everything. Every small bit helps. Use cloth shopping bags. Avoid plastic bags. Avoid using lights in the morning. Open your curtains and let sunlight come in. But do not open your window shutters and curtains if the air conditioning is on. Keeping the temperature of your AC above 24 can help to reduce green house gas emissions. Avoid using plastic disposable cups. Dry your clothes in the sun and not indoors.
Reuse
Reusing can automatically reduce. You can use shallow plastic trays that we often get in chocolate boxes for germinating seeds. Just put a layer of cotton on it and place the seeds and cover them with a thin layer. Fill a deeper tray or tub (like youghurt tubs..see pictures) with soil and plant the saplings in them. Once they are of considerable height, they are ready for the natural world. Avoid buying things that you dont need and using what you have efficiently and conservativly. Use one-side-used paper as rough paper.
Recycle
Recycling can be a bit difficult at home. The simplest way however is composting. Just bury some organic wastes from your kitchen in the soil and cover it with a shallow layer. You can also recycle paper and make it into cards. Be creative and try to make the best of old cardboad, paper and other stuff.
