Overall global warming is a serious issue concerning all of us. However, there are a few particular things that we must seriously keep in mind. One of the main major concerns of global warming is sea level rising. Also, we must consider how warmer temperatures could destroy our ecosystems and affect the food chain. Lastly, there are health concerns associated with global warming. Some people argue that climate change is a part of Earth's natural cycle but there is much scientific evidence supporting otherwise. With all this and much more, we need to be extremely careful in our actions and to our part to try to make a difference.
