The harmful consequences can be eliminated by eating less meat
But driving less and eating less meat won't feed the hungry.
Genetically engineered animals produce better eggs, milk, and meat. Chickens are designed to lay low-cholesterol eggs, cows to produce skimmed milk, and pigs to produce pork with less unhealthy omega-6 fatty acids and more healthy omega-3s.

Growing meat tissues in cell cultures would produce a number of desirable consequences: it would be a good source of protein, less fatty/more nutrient rich meat than conventionally raised animal products, less polluting, reduce fossil fuel and water consumption, eliminate food born disease, scale back on farmland currently used for feeding and raising animals. It would taste like processed meat, such as sausage, hamburger, chicken nuggets, or fish sticks. The only undesirable consequence of in vitro meat currently is the cost. The animal welfare, environmental, and human health benefits outweigh the harms, therefore it is morally permissible to produce and consume in vitro meat.
Could Veganism End World Hunger
Animals – some more than others – add an intrinsic inefficiency into the food chain, using up energy for such things as walking around and keeping warm (per kilo of meat, poultry do a lot less of less of this through their lives than cows, making chicken a significantly more efficient energy source than beef). A mere 500 calories per person per day come back out of the animal food system as meat and dairy foods. So the inefficiency of our meat and dairy diet leads to a loss of 1,200 calories per person per day, excluding any grassland that could be used for edible plant crops. And meat consumption is in developing countries.

We need to be asking how plants can become more aspirational foods than cows. But if we are still going to eat meat, stick to chicken which has only about one-tenth of the carbon footprint per kilo of Brazilian beef. This is partly because a chicken is a more energy-efficient meat producer, partly because chickens don’t ruminate, or chew the cud (which emits methane, roughly doubling the footprint of a cow) and partly because chicken farms are less strongly associated with deforestation.
