Read the following text and fill in each gap with a suitable word based on the information of the text:

Everyone must play a part in protecting the environment. There are many things we can do on our own every day to help save the planet. The best thing we can do for the planet is to use its resources properly. Before buying something, we can ask ourselves, "Do we really need this?" Or "Is there another product which would do the same thing but is more sustainable?" Or ask the question, "Will this last a long time?" When we buy things, we should buy those that are durable; we should use them properly, and have them repaired when necessary. If we practice this, many things will not only last a life-time, but also be passed on for future use. However, if something is truly unusable for its original purposes, try to be more creative and think of how else it might be used. Rather than throwing an item out when neither we nor anyone else can make use of it, have it recycled. And if recycling is not possible, it is better to send goods to a landfill or have them burned up.
