Correction of a few sentences

[Offroad]

Dear teachers,

Could you check if the sentences below read well?

Biomasses are known to grow in a sustained way through the fixation and release of CO₂, mitigating global warming problems. In fact, the amount of CO₂ produced during the combustion of fuels is the same as those absorbed during plants cultivation.

Thank you
