Earth hour is often overlooked as it only accounts for one hour out of a year of over consumption of electricity. However, the role it plays in raising awareness for environmental causes is crucial in creating a sustainable future. I designed this poster to help raise awareness for the cause and to remind people of the upcoming environmental holiday. I use a grid system while designing my posters that leads to a very structured design and helps to create a consistent feel between multiple posters. Design is a very powerful tool for creating change in the world and this is something to keep in mind when creating anything. The way a design will function and the impact it is designed to make is one of the most important aspects of any design.
