"Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it's about 20 tons. For people in poor countries, it's less than one ton. It's an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero"

This quote by Bill Gates is a stark suggestion of the environmental crisis we are facing. He explains that the average American produces 20 tons of carbon dioxide every year, while individuals in poorer nations produce much less. Usually, everybody on earth produces five lots of carbon dioxide. This is an unsustainable amount and we must make changes to lower it to absolutely no. This will need a worldwide effort to reduce emissions and switch to renewable resource sources. We should also work to decrease our usage of resources and increase our recycling efforts. It is clear that we need to act now to safeguard our world and make sure a sustainable future.
