Not all biofuels are good for the planet

Cathay Pacific is planning to use biofuels to meet strict carbon emission requirements. This is great news, because if airliners use renewable energy, it will benefit the environment.

However, if using biofuel means burning corn and fermenting crops to generate ethanol, this can be quite damaging.

If more biofuel is needed, then more farmers will grow crops for biofuel and not for food. This may increase the cost of food. If food prices are too high, poor people in developing countries will suffer and millions could die from starvation.

Also, as more land is needed to grow crops for biofuel, large areas of forest will be destroyed. Then more carbon will be released into the air and the problem of global warming will become worse.
