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 three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are either unreachable or too polluted
Famine Carmen Kaljulaid 11 a World Hunger, Poverty & Famine: How They Fit Together 923 million people across the world are hungry. In essence, hunger is the most extreme form of poverty, where individuals or families cannot afford to meet their most basic need for food. Hunger manifests itself in many ways other than starvation and famine. Most poor people who battle hunger deal with chronic undernourishment and vitamin or mineral deficiencies, which result in stunted growth, weakness and heightened susceptibility to illness. Countries in which a large portion of the population battles hunger daily are usually poor and often lack the social safety nets we enjoy, such as soup kitchens, food stamps, and job training programs. When a family that lives in a poor country cannot grow enough food or earn enough money to buy food, there is nowhere to turn for help. Facts and Figures on Hunger, Famine and Poverty In the developing world, more than 1.
WATER POLLUTION THERE ARE THREE DIFFERENT WAYS THAT WATER CAN BE POLLUTED. ⦿ Surface Water Pollution - Most common type, you can visually see the pollution floating (plastic containers or oil and gasoline spills). ⦿ Ground Water Pollution – This becomes more relevant as it affects our drinking water. It become infected by toxic chemicals. ⦿ Microbial Pollution – Found in the countries who don’t have the facilities to cure the water so the bacteria and viruses grow in the water. The people have no other way of getting water so they are forced to drink it. WHAT CAUSES WATER POLLUTION? ⦿ Wastewater ⦿ Marine dumping ⦿ Industrian waste ⦿ Radioactive waste ⦿ Oli pollution ⦿ Underground storage ⦿ Global warming WHY IS IT A PROBLEM? ⦿ It causes worldwide disasters and deaths. ⦿ It may not damage our health immediately but can be harmful after long time. ⦿ Industrial waste often contains many toxic compou
Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water poll
Overpopulation Tuuli Tomingas TK18 What is overpopulation? When some kind of area has too many people or... When human population is too big and social or natural structure can not fulfill the needs. The most problematic areas Africa Asia South-America Global problems Air pollution Garbage Destruction of rainforests Non-renewable resorces Community problems Bad food and water quality or at all their lack of.

Third World countries are often described as "developing" while the First World, industrialized nations are often "developed". A lack of material wealth does not necessarily mean that one is deprived. A strong economy in a developed nation doesn't mean much when a significant percentage (even a majority) of the population is struggling to survive. Politics have led to dire conditions in many poorer nations. In many cases, international political interests have led to a diversion of available resources from domestic needs to western markets. This has resulted in a lack of basic access to food, water, health, education and other important social services. This is a major obstacle to equitable development. Poverty has also been described as the number one health problem for many poor nations as they do not have the resources to meet the growing needs. But poverty is not restricted just to developing countries. Industrialized nations are also seeing a sharp increase in poverty. While th
Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history. Even in Ancient Romepeople complained about smoke put into the atmosphere. The effects of air pollution are diverse and numerous. Air pollution can have serious consequences for the h

Over the next four decades, Christians will remain the largest religious group, but Islam will grow faster than any other major religion. If current trends continue, by 2050 … The number of Muslims will nearly equal the number of Christians around the world. Atheists, agnostics and other people who do not affiliate with any religion – though increasing in countries such as the United States and France – will make up a declining share
