Farmers can get away with a lot more than a big tractor or a large crop rotation in many parts of the world.
In some places, they can simply move to a new area.
And the cost of raising livestock has fallen so dramatically in recent years that even small family farms can feed large families.
But there’s still a lot of work to be done, according to a global study released Wednesday that shows the need to get more efficient with food production.
What you need to know about the study: The United Nations Food and Agriculture Organization (FAO) said in a release that it is the largest international food security assessment ever conducted on livestock and that the findings show that there are currently more than 400 million animals in the world, up from about 350 million in 2010.
In its first edition in 2016, the report said that livestock production is already nearly 40% higher than it was in 2000.
The report says that the United Nations estimates that livestock are now responsible for about 10% of the total greenhouse gas emissions in the global economy, but that their contribution to the planet is projected to grow as a share of total greenhouse gases, from 20% in 2050 to 41% by 2100.
That would translate to a total of 1.5 billion tons of CO2 being emitted by livestock each year.
However, the FAO says it is also important to recognize that many parts in the developing world have seen their livestock production fall by about 50% in recent decades, so even the most efficient farm systems may not be enough to meet global food demand.
“Many countries have seen the biggest losses in livestock production over the past few decades and there are many countries that have been unable to keep up with population growth,” the FAo said.
“Many countries are now experiencing food security challenges that cannot be overcome without significant investment in livestock, including agriculture, conservation, education, and food systems.”

The report also highlights some of the challenges that countries are facing in food security, including:A growing global population is pushing up the costs of raising meat and milk production in many developing countries.
The number of cattle in a country has increased by more than 70% since 1970.
But that has not been enough to keep livestock prices in check as livestock prices have more than doubled over the same period.
The FAO estimates that the cost per head of beef has increased from $0.07 in 1970 to $1.13 today.
That has driven up the cost for many rural and urban areas, as well as many countries with low populations.
The average price of chicken and pork, for example, has increased nearly 150% since 1980, according the FAOC.
In China, livestock prices jumped from $1 per head in 1980 to $14 in 2015.
That’s more than 30 times the rate of growth of the overall economy.
But the FACO report notes that while livestock prices may be rising in some areas, in other countries the prices are falling and that some of those countries may need to increase prices if they are to meet their food security needs.
The FAO report says the United States has the lowest per capita meat consumption in the developed world and the lowest average consumption of milk, eggs, fish and dairy products per person in the whole of the developed globe.
And while the FAOMC says that China has the second-highest per capita consumption of animal protein, the number of dairy cows is less than half of those of the United Kingdom and Italy, which have higher per capita protein consumption.
