Climate Change is definitey an enormous hazard towards to the human race. However there is something you can do about it. No matter what age you are you can make a difference. For example, take a look at David Attenborough, he is 96 but still has the strength to help us humans and the planet. If he wanted to he could have obviously just sat at home and done nothing, but he didn't, instead started as a naturalist (an expert in or student of natural history.)in 1952 and ever since has been teaching us humans about the dangers our environment is facing. He does this by creating entertaining documentaries that educate us thoroughly about our climate. He made a difference so why can't you.
One way you can take action is to start a meat and dairy free diet, in order to decrease your carbon emissions. This would create a huge impact on battling against climate change.
Another way we can take action is decrease our use of use of energy in homes. For example, turning off sickets when not in use or switching of lights when not in a certain room. This will help save energy in the house and prevent paying more electricity bills
These are just of a few of the simple things you can do to help out the climate. You don't have to well know or famous to make a difference. We can all make ourselves useful and save our planet.
