perfectly fit into our daily routines， and virtual landscapes coexist with reality．From technological advances to climate change impacts， the next few decades will undoubtedly reshape the structure of our existence． 　　In this new era， artificial intelligence and robotics will take center stage， transforming how we interact with our environment and one another．They will have evolved from mere tools to companions that predict our needs and desires．The once－distant dream of having AI－driven personal assistants is now a reality， as they manage our schedules， handle our communications， and offer personalized recommendations with extraordinary accuracy． 　　However， as we fast－forward to 2050， one cannot help but think about the huge effects of climate change on our planet．At present， most of us are lacking the imagination of what daily life will be like when we have slashed our carbon emissions （碳排放物）， from our homes and food to travel and the landscapes around us．What follows is an attempt to show you how a day will look in a net zero greenhouse gas emissions world． 　　Edie Vaughan， a young girl in 2050， lives in Toronto， Canada， a place that is among the most popular destinations for its healthy climate and clean water resources．There are forests， and giant machines taking carbon dioxide （二氧化碳） out of the atmosphere．At that time， there are no office or industrial jobs anymore： artificial intelligence and robots have taken care of that．The few jobs left are in service， culture or health care．Luckily， Edie has her job．Every morning， she checks the balance in her Personal Carbon Allowance （PCA） account to see if she has enough to buy another battery for her e－bike．If she doesn’t have enough then she will have to buy carbon credits， and they are expensive． 　　This story of 2050 is one of hope and possibility — a reminder that while enjoying the convenience brought by technological progress， we should also be responsible for the environment．
