October 31 humanity overstepped 7 billion milestone. And in 2100, the world population will exceed 10 billion, and even, perhaps, closer to 15 billion if birth rates in the world will increase slightly.
UN experts have decided to appoint the birthplace semimilliardnogo earthling Kaliningrad, as it is impossible to calculate exactly which of the unborn child "open account", and this action is symbolic. At 0 hours 2 minutes of local time at four Nikolaeviches son, who was named Peter. Growth of the boy, said the Kaliningrad perinatal center, 50 cm, weight — 3 pounds 60 grams.
The decision to bestow a newborn from Kaliningrad conditional title semimilliardnogo person on Earth because it is in the Kaliningrad region will include a presentation of the world report on the population of the planet, which will analyze the problems of the world with the increased population.
The UN estimates that by 2050 the world population will be 9.3 billion by the end of the century that number will exceed $ 10 billion. The growing number of people in the world, however, can add serious issues facing humanity.
In the report, UNFPA (UNPO Fund for Population) raised issues such as the problem of youth employment in poor countries, environmental problems, finding the balance between urban and rural populations and migration. Asia is projected to remain the most populated part of the planet. Its population, now numbering 4.2 billion people, will increase to 5.2 billion in 2052. Africa's population, meanwhile, with one billion increase to 3.6 billion in 2100. With such dynamics in the near future, Africa will inevitably face the problem of lack of water, food and jobs for citizens. These problems and now acute for some countries.
Population in other areas, including the Americas, Europe and Oceania, from 1.7 billion in 2011 to rise to 2 billion in 2060. Population growth will extend human life and improve the quality of, say UN experts. But for many, these benefits will remain available, the report recognizes UNFPA.
Yet, according to many researchers, the main problem is consumption, not persons. Experts call to reflect on the protection of the world in which we live, and give simple tips you can follow each.
If possible, buy energy-efficient appliances. It should be labeled accordingly. The most cost-effective devices are labeled A, A + and A + +. Do not forget, home appliances, released 15-20 years ago, uses twice as much energy than current models.
Let's take a "rest" your computer. Switch to a standby mode each time the interrupt work for a long time. After turning off the computer unplug. Flat-panel monitors, laptops consume less electricity than monitors with cathode-ray tubes and stationary computers.
Hi-Fi systems, TVs, VCRs, computers and other devices consume power even in "sleep" mode. For the year, the cost of electricity used during operation of appliances in "sleep" mode, can reach several thousand. To avoid this, turn off appliances from the outlet when not in use, or use the "rosette-pilots" button to disconnect device.
Use compact energy saving lamps. They consume 3-5 times less electricity than incandescent bulbs. Whatever lights you use, turn off the lights when it is not needed.
Do not leave the charger connected to the socket. They consume electricity even when not in use.
Cooking at home in every way more profitable than "fast food" and the use of deep-frozen. Even standing at the stove, you can save energy and the family budget. During cooking, keep the pot covered. Use a small amount of water to boil eggs or vegetables. Use a pressure cooker. Do not turn the stove in advance. If cooking on electric stove, use the residual heat — turn off the burner just before the full cooking.
The process of heating water is the second largest after the heating energy consumption of air. We must always remember this and economical use of hot water. In some cases — for example, in rural areas, the sun can heat the water and dry clothes for free and without damage to nature.
Take showers instead of baths. Turn off the water while you lather. Use special nozzles on shower and faucet, reducing water consumption.
Save money on laundry, setting on a washing machine a lower temperature — it can reduce power consumption by 80%. Try to fully load the washing machine and dry clothes in the sun. If a family of 4 people will stop using electric drying, it will save over 480 kWh per year and prevent the emission into the atmosphere of 300 kg of CO2. Do not use toothbrushes, razors and other devices on the battery or batteries.
If you still can not do without them, be sure to charge them properly.
If possible, use public transport. Buses and commuter trains are three times more efficient than private cars. City trams — is probably the most environmentally friendly mode of transport, and in the future it may become even more efficient. Often go on foot. Hiking not harm nature and beneficial to your health.
Buy high-quality clothing and appliances. Quality products last longer, and therefore, will be spared the natural resources necessary for their production.
Following these tips will allow humanity to improve the quality of life, leaving behind a trail of destruction and disasters.
