1. What food will we be eating in 2050? By 2050, individuals will be eating cultured, or cultivated, meat, high-protein insects, seaweed, algae, and allergen-free nuts. All of this food is rich in essential vitamins and minerals and high in protein.
By 2050, the global population is expected to hit 10 billion people. This means that – to feed everyone – it will take 56 per cent more food than is produced in the world today, according to the United Nations Environment Programme (UNEP).
Demand for meat is only going up
And production is expected to continue to grow. By 2050, global meat consumption is projected to reach between 460 million and a staggering 570 million tons.
The World Resources Institute (WRI) reports that a 25 percent reduction in food waste would push food production 12 percent closer to the levels necessary to feed the world in 2050 and would shrink the amount of increased agricultural land needed by 27 percent, inching closer to fully closing the land gap.
It would be far easier to feed nine billion people by 2050 if more of the crops we grew ended up in human stomachs. Today only 55 percent of the world's crop calories feed people directly; the rest are fed to livestock (about 36 percent) or turned into biofuels and industrial products (roughly 9 percent).
With the expansion of the world's population to 10 billion by 2050, this means that food production must more than double to avoid truly widespread hunger and malnutrition. However, in the face of climate change, depletion of natural resources and diminishing arable land, the world's farmers face increasing challenges.
Barley, oats, and rye were eaten by the poor while wheat was generally more expensive. These were consumed as bread, porridge, gruel, and pasta by people of all classes. Cheese, fruits, and vegetables were important supplements for the lower orders while meat was more expensive and generally more prestigious.
So our diets may be more veg and fruit, whole grains and vegetarian food or new alternatives (soya products, or perhaps insects or artificial meat), and less fried and sugary things. We'll still eat meat, but, perhaps more like our parents and grandparents, see it as a treat to savor every few days.
Despite the media hype and investments in marketing, lobbying and advertising, synthetic and vegetable meat do not solve environmental problems, and pose a health risk. This was revealed by the new IPES-Food report.
Future Foods is about applying innovative biotechnology to create, manufacture and export appealing new food products and ingredients that are nutritious and sustainable.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
There is a big shortfall between the amount of food we produce today and the amount needed to feed everyone in 2050. There will be nearly 10 billion people on Earth by 2050—about 3 billion more mouths to feed than there were in 2010.
"The Romans believed it was healthier to eat only one meal a day," food historian Caroline Yeldham told BBC News Magazine in 2012. "They were obsessed with digestion and eating more than one meal was considered a form of gluttony. This thinking impacted on the way people ate for a very long time."
Prior to about 3.5 million years ago, early humans dined almost exclusively on leaves and fruits from trees, shrubs, and herbs—similar to modern-day gorillas and chimpanzees.
Hunter-gatherer societies ate raw meat. Hunter-gatherers also ate plants found in the wild, such as seeds, nuts, and berries. By the end of the Stone Age, humans began to grow their own crops, domesticate animals, and use fire to cook food.
Based on these trends Australia's population is projected to reach 35.9 million in 2050. Population growth, by supporting reduced ageing of the population and adding to the labour force, benefits the Australian economy but puts pressure on infrastructure, services and the environment.
However, producing enough food to feed the world does not guarantee food security. Hunger exists today although there is enough food for all. Even if we increase agricultural output in 60 per cent by 2050, we will still have 300 million people going hungry due to lack of proper access to food.
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. [ How Do You Count 7 Billion People?] One such scientist, the eminent Harvard University sociobiologist Edward O.
