Save great cities like Miami from disappearing There are more greenhouse gases in our atmosphere this year than ever before . Yet if we continue at this pace, Earth could warm between two and six degrees Celsius over the next century – resulting in catastrophic consequences for humans and planet . Consuming less by taking personal action is a major, but under-valued solution to preventing climate change. People have a growing appetite for things whose production, transportation, use and wastage create greenhouse gas emissions, driving a climate breakdown . To keep global warming to 1.5 degrees – the global temperature threshold before many major world cities like Miami go under water , coral reefs and ice sheets disappear, crops start failing and other big issues - all Europeans would need to reduce their personal carbon footprint by approximately 8 tonnes of CO2 per year . To reduce it by that much, we'd probably need to eat a local, seasonal, plant-based diet, forgo flying and live car-free, use renewable energy to power our homes, recycle all waste, wash clothes with cold water and hang dry them, and not buy any new clothes or gadgets . HOW TO FIX IT: Save great cities like Miami from disappearing by the end of the century. If we all take action to use less stuff, we can have a major impact. Acquiring few, but useful and long-lasting possessions, eating meat-free, and ensuring little to nothing gets wasted and ends up in landfill are all impactful ways to shrink our footprint.
