Despite the downvotes, you do make an important point. In order for space travel to be feasible, efforts are needed to mitigate and reduce the environmental impacts of chemical rockets. For cargo, it could be possible to use electromechanical means of propulsion that may involve acceleration before what a human body is capable of.

Best would likely be a space elevator powered by nuclear and/or renewables. This could greatly reduce the amount of pollution involved in transiting between the Earth and orbital positions.

Plants consume CO2. As CO2 levels increase in the air, plants grow more photosynthesizing material to take advantage of the resource.

Search Labs | AI Overview Learn more… The amount of carbon dioxide (CO2) emitted by a SpaceX rocket depends on the stage of the launch and the type of rocket:

Starship
According to Andrew Wilson, an assistant professor at Glasgow Caledonian University, one launch of SpaceX's Starship rocket produces 76,000 metric tons of carbon dioxide equivalent (CO2e), which is a measurement that combines different greenhouse gases into one unit.
Falcon 9
According to an independent study, the amount of CO2 emitted by the Falcon 9 rocket in the lower atmosphere isn't significant compared to the surrounding air. However, in the mesosphere, which is 30–50 miles above Earth, the rocket emits the same amount of CO2 as 26 cubic kilometers of the surrounding air as it travels 1 kilometer.
Other launches
In 2022, the BBC reported that one SpaceX launch emitted around 116 tons of CO2 in 165 seconds during the first stage of the launch. In general, rockets emit around 200–300 tons of CO2 per launch
