I am assuming that you are looking for a list of ways to avoid global warming. One thing to keep in mind is that global warming is most likely already here. So in reality we can't avoid it, but we can slow it down.
One cause of global warming is deforestation. Deforestation is "the removal of trees without sufficient reforestation. This has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. So if deforestation is one cause of global warming you could plant trees or roof top gardens.
Continued recycling of waste will help prevent global warming. Using old things in new ways instead of creating tools from the environemt can assist with helping the environment.
Using public transportation is another way to slow down global warming.
