Human overpopulation Liis Lukk MJ15 What is overpopulation? • Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. • Human overpopulation is among the most pressing environmental issues • Overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources • Human population has been rising continuously since the end of the Black Death, around the year 1350 • The most significant increase has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity • The recent rapid increase in human population over the past

pollution. Clean air and water are the most valuable resources, but they are getting more and more polluted. For example the air in China is so polluted that people need to wear masks. The pollution of water kills hundreds of thousands of water animals and birds. Some of the big companies have accepted the problem and are taking action. For example McDonald`s and Burger King are not using plastic straws anymore. Second thing that affects the life on Earth is overpopulation. The estimated population in 2050 is near 10 billion. Population growth also raises overconsumption. People are encouraged to consume by companies and their commercials. The problem is that humans are consuming more than the Earth can regenerate. The exhaustible resources are running out. And with the population growing, it will become an even bigger probleem. This means people in the future may not have enough resources, because right now humans are using too much.
Problems of 21th century city The cities of the 21th century are the biggest mankind has created besides incorporating newest technological innovations, however, even despite all the advanced technological applications, modern metropolises have many of the same problems as cities 200 years ago. Only this time around these issues are even greater due to the size of cities, so what are the two biggest problems? One of them is most likely going to be overpopulation, which is inevitable due to the overall growth of the human population and urbanisation. However, that is not all, as pollution levels are on the rise and with like everything else, the bigger the city, the bigger the problem. These matters are the results of multiple factors, thus in order to solve these issues, multiple coherent solutions are called for. The first problem is the result of growing human populous of Earth; this can be halted only

seals. When hunting is good, polar bears will typically eat only the fat and leave the rest of the carcass for scavengers including arctic foxes, ravens, and younger bears. Polar bears also sometimes kill and eat both walrus and beluga whales. They have even hunted short-legged reindeer and sometimes even birds and bird eggs. Polar bears are top of the food chain in the Arctic. They help to keep the balance of nature by preventing an overpopulation of seals. In the wild, polar bears live an average of 15 to 18 years, although biologists have tagged a few bears who are 30 years old. One zoo bear in London lived to 41. Female polar bears have their first set of cubs between the ages of four and eight (most frequently at age five or six). At birth, the cubs are 30 to 35 centimeters long and weigh little more than half a kilogram. They are blind, toothless, and covered with short, soft fur. The cubs are born in November or

had to live on the streets. Slums started appearing in bigger towns. Crime rate was also rising because of this: many homeless children lived by stealing and respectable Victorians started seeing poor people as a threat to society. That is one of the reasons why workhouses were made. Workhouses Workhouses were supposed to solve the problem of poverty, because wealthy people believed that poor people were poor only because they were lazy(actual causes were overpopulation, unemployment and high prices). So in 1834 a law was passed in the Parliament that resulted in building workhouses to accommodate and give jobs to people who couldn't support themselves financially. Also in the workhouses were orphaned (children without parents) and abandoned children, the physically and mentally sick, the disabled, the elderly and unmarried mothers. The idea of workhouses was kind of good, but in reality, there were several problems with them

majorly caused by industrial waste that deprives soil from essential nutrients. FIND OUT 5 WAYS HOW TO STOP POLLUTION. 2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth surface causing melting of polar ice caps, rise in sea levels and also flash floods, excessive snow or desertification. FIND OUT 5 WAYS HOW TO STOP GLOBAL WARMING. 3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food, damages the environment through use of chemical fertilizers and pesticides. FIND OUT 5 WAYS HOW TO STOP OVERPOPULATION. 4
Economic growth slowed considerably in 2001-02, as part of the global economic slowdown, but for the four years before that, annual growth averaged nearly 4%, well above the EU average. (3) 1.4 Population The great majority of inhabitants of the Netherlands are Dutch. They are mainly descended from Franks, Frisians, and Saxons. Most residents of Friesland Province are Frisian, a distinct cultural group with its own language. Fearing overpopulation, the government encouraged Dutch emigration after World War II (1939-1945), and some 500,000 people left. But an even larger number of people entered the Netherlands--Europeans and Asians from the former Netherlands Indies dependency (now part of Indonesia); industrial workers from Turkey, Morocco, and other Mediterranean countries; and, more recently, residents of Suriname, also a former Dutch dependency and the Netherlands Antilles. Consequently, the country's

We will lose another 72 square miles to encroaching deserts, as a result of human mismanagement and overpopulation. We will lose 40 to 100 species, and no one knows whether the number is 40 or 100. Today the human population will increase by 250,000. And today we will add 2,700 tons of chlorofluorocarbons to the atmosphere and 15 million tons of carbon. Tonight the Earth will be a little hotter, its waters more acidic, and the fabric of life more threadbare. The truth is that many things on which your future health and prosperity depend are in dire jeopardy:

I chewed slowly, and then took a long drink of Coke without looking up. "So," I said after a moment, finally meeting his now-anxious gaze. "What's your favorite?" He raised an eyebrow and the corners of his mouth turned down in disapproval. "Mountain lion." "Ah," I said in a politely disinterested tone, looking for my soda again. "Of course," he said, and his tone mirrored mine, "we have to be careful not to impact the environment with injudicious hunting. We try to focus on areas with an overpopulation of predators -- ranging as far away as we need. There's always plenty of deer and elk here, and they'll do, but where's the fun in that?" He smiled teasingly. "Where indeed," I murmured around another bite of pizza. "Early spring is Emmett's favorite bear season -- they're just coming out of hibernation, so they're more irritable." He smiled at some remembered joke. "Nothing more fun than an irritated grizzly bear," I agreed, nodding. He snickered, shaking his head
