Population that is more prosperous and compete to acquire the resources that can make the world more rare "beyond recognition" at the latest in 2050, according to several researchers in major Science Conference in the us.
The United Nations has predicted the global population will reach seven billion in this year, and growing so nine billion in 2050. "Most of the growth of it happening in poor countries, particularly in Africa and South Asia," said John Bongaarts from non-profit Population Council.
To feed all the mouth was, "we will have to produce as much food in 40 years into the future as we have done in 8,000 years later", said Jason Clay from the World Wildlife Fund in the annual meeting organized by the American Association for the Advancement of Science (AAAS).
"Up to 2050 will have the rest of the planet who can spot", if the current trend continues, said Clay. The population grew to memparah problems, such as the depletion of resources, said John Casterline, Director of the Initiative in Population Research at the Ohio State University.
However the human also estimated income will go up for 40 years into the future--tripling globally and so eight times in developing countries. The condition that it adds to the weight of the load to the global food supply.
People tend to come up to the series of food outlets as their earnings increase. They consume more meat than when their earnings, said experts.
It takes as much as 3.4 kilograms of grain to produce one pound of meat, and as much as three to four pounds of grain to produce one pound of cheese or a couple of eggs, said the experts.
"More and more people, more money, more and more consumption, but the planet's remains," said Clay told AFP. He urged scientists and the Government to start making changes now to produce food.
Meanwhile, demographers are calling for more funding for family planning programs to help control the growth of the number of human beings, especially in developing countries.
"For 20 years, very little capital investment in the sector family planning, but the attention started turning again now, partly because of environmental factors such as global warming and food prices," said Bongaarts.
"We want to meminimkan population growth, and the only available way to do that is through family planning programs are more effective," said Casterline.
Rising global temperatures is expected to lead to other changes such as rising sea levels, increasing the intensity of extreme weather phenomena, as well as changing the amount and pattern of precipitation. The effects of global warming is terpengaruhnya the other agricultural products, the loss of glaciers and the extinction of various kinds of animals.
Due to global warming and the need for a human stomach very pressing large species of fish in the sea. Overfishing by humans make more little big fish swimming in a variety of predators in the ocean of the world, said some scientists.
"Overfishing of course has been going on and giving effect ' when there is no cat, the rat to roam ' against a sea of us," says Villy Christensen, a professor at the UBC Fisheries Centre.
The researchers also found that more than half (54 per cent) of predatory fish population slump has occurred during the last 40 years. As many as 76 million tons of seafood commercial is reported to have arrested in 2006. It means "seven billion animals are killed and consumed by us or our cattle," said UBC scientists Reg Watson.
Watson said the activities of fishing has evolved over several decades later, so the overall to reach 1.7 billion watts, or 22.6 million horsepower, all over the world that year.
