It can be hard to visualize the huge network of hardware that allows you to send a request for a page to a server and then receive a response back. Also, the amount of data that is required for the page, and the complexity of the route it must travel through, will determine the amount of carbon released by the network itself.

Having said that, looking at data over the past ten years, it's safe to make the observation that pages are definitely trending bigger.

Yet, this criticism of React isn’t completely unwarranted: React and ReactDOM total about 120 KiB of minified JavaScript, which definitely contributes to slow startup time. When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware.
