That is a very myopic perspective. You are using a computer and internet that uses electricity that is produced using fossil fuels and all its components are produced directly of fossil fuels/oil and/or only able to be extracted from the earth by the use of fossil fuels.

You live in a house/home that was produced by the use of fossil fuels. Likely every single thing all around you wherever you are right this second is made of or with fossil fuels.

Plastics, the building, soaps, lotions, the table and chair, the lamps and lightbulbs, the cables, the microwave and oven/stove, the carpet/flooring, your clothing, any makeup you use, the toilet paper, deodorant, all your food (even produce), the packaging of your food, the preservatives that are used to feed you in your city that is so far away from food sources, … and on and on and on. … ALL use and made with fossil fuels.

Planes make up a small percentage of fossil fuel emissions, in fact, rice production is closely behind it in pollution statistics.

That's the same argument as "we don't need to bother about our own consumption because China has coal-fired power stations".
