Do you really think that farmers in developing countries have it easier than those in developed countries? That they can more easily afford the cost of environmental regulation?
The carbon footprint of the average American or Canadian is about 14 tones per year. For India, Indonesia, and Brazil it's about 2 tons per year. Thus it is fair to expect developed countries to do more to tackle climate change.
Having said that, industrial agriculture done right is better for the environment because it's more efficient. The amount of land needed to feed an average person is minimised, thus there's less pressure to convert forests, grasslands and peat bogs to farmland.
