Endangered and critical elements are substances that we use in many things. There are 44 elements that we might not have enough of in the future. Some of these elements are rare and valuable, while others are important for plants and animals. We need to manage how we get and use these elements so we don't harm the environment. We need to find better ways to get these elements, use them efficiently, and recycle them so we don't run out. This will make sure we have enough for the future.
The periodic table below shows a list of endangered elements and when they are likely to run out based on our current usage.
