The best solution is - B. replacing fossil fuels with renewable energy sources.
By replacing the fossil fuels with renewable energy sources the enormous release of carbon dioxide into the atmosphere will be stopped and minimized because the renewable energy sources are not emitting Greenhouse gasses into the atmosphere.
Unfortunately, this type of energy sources still can not satisfy the demand, and also big problem represents the economic justification of their usage, and lots of countries are not willing to lose profit in order to protect the environment.
In some cases yes, but most of the time no, all animals have to adapt to the ecosystem, if one thing is off the whole ecosystem fails, in hence not reaching homeostasis.
