there will be increased competitiveness for these resources which leads to elevated crime rates due to drug cartels and theft by people in order to survive. • It has been observed that the countries which have balanced population, crime rate is very low in such regions. When people are not provided with the basic necessities, it elevates crime rate."

We do not inherit the Earth from our ancestors; we borrow it from our children There is a saying that „we do not inherit the Earth from our ancestors, we borrow it from our children.“ Nowadays people don not think about it and are ruining the planet. There are researches which say that the human life on Earth will go extinct within a century. Eventually the Earth will become uninhabitable. People cannot change the past but their actions affect the future. One of the ways how people are affecting the lives of future generations is increasing 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 M...
A world government is both desirable and necessary. A world government is both desirable and necessary. What is there to gain from a world government? Are there any downsides to such world order? A lot of people believe that a world government is the only way in future. It would unite countries and people, eliminating differences. What would help to preserve peace in the world. Also a world government would help to rationalize recourses. As there would not be any duplicating, allowing much faster development of new technologies and faster production. In addition recourses would not pile up in one place because they would be diverted to places where the need is greatest. But there is a downside to a world government. Through unification of people and countries, smaller nations would lose their identity. It means smaller nationalities would simply fade away, they would be dissolved. Because the influence ...

Eesti Maaülikool Põllumajandus- ja keskkonnainstituut Maakera rahvastiku eksponentsiaalne kasv ja protsessiga seotud ökoloogilised probleemid Referaat Juhendaja: lekt. Merle Ööpik Tartu 2012 Sissejuhatus Rahvastiku kasvutempot ja rahvastiku kasvu üleüldiselt hakati inimeste poolt endile probleemina teadvustama 1960 ndatel. Selleks ajaks oli ületatud kolme miljardi inimese piir. Sai selgeks, et tollase kasvutempo juures saavutatakse maakera taluvuspiir ruttu ja ka loodusvarud hakkasid näitama märke nende otsalõppemisest. Referaadis käsitletakse maakera rahvastiku kasvu, selle põhjuseid ja sellega kaasnevaid probleeme. Maailma rahvastiku kasvust ja ülerahvastatusest Rahvastiku kasv on muutus rahvaarvus mingi aja jooksul. Rahvaarvu 12 000 aastat tagasi hinnatakse umbes neljale miljonile inimesele, alates seal...
Polar bear Ursus maritimus or the "sea bear." Polar bears live near the circumpolar at north in areas where they can hunt seals at open leads. Scientists estimate that there are between 22000 to 27000 polar bears. Its closest relative is the brown bear. Adult male polar bears are 2,5 to 3 meters tall. They weigh 250 to 770 kilograms. Adult female bears are smaller. They are about 1,8 to 2,5 meters tall and weigh 90 to 320 kilograms. Polar bears usually eat seals usually the ringed seasl, but sometimes the bearded 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 cha...

Maailma rahvaarv kasvab ohtlikult suureks Rahvastiku arv hakkas kiirelt kasvama 18. sajandil tänu meditsiini arengule ning elutingimuste paranemisele. Esimene miljard inimesi täitus maakeral 1804. aastal, teise miljardi täitumiseks kulus pärast seda 123. aastat, kolmanda miljardi täitumiseks vaid 33. aastat. Kuue miljardi piiri ületas maailma rahvaarv 1999. aastal. Peale seda on rahvaarv iga aasta plahvatuslikult kasvanud. Maailma rahvaarvu suurenemine toob kaasa palju probleeme, mis seab ohtu terve inimkonna elu ja arengu. Rahvaarvu kasv on põhjustanud suuri sotsiaalseid ja majanduslikke probleeme - toidu puudus (arengumaades), ülerahvastumine ja -linnastumine, tööpuudus, suurenev majanduslik ebavõrdsus, suurenev nõudlus loodusvaradele, jäätmete ladestamise probleem jne. Rahvaarv tõuseb eriti kiirelt arengumaades. Sellel on mitmeid põhjuseid, nagu näiteks arengumaades on naised põhiliselt kodus ...

15. Victorian times Life and conditions of Victorian people Children were expected to help towards the family budget. They often worked long hours in dangerous jobs and in difficult situations for a very little wage. For example, there were the climbing boys employed by the chimney sweeps; boys and girls working down the coal mines, crawling through tunnels too narrow and low to take an adult. Some children worked as errand boys, crossing sweepers, shoe blacks, and they sold matches, flowers and other cheap goods. During the Victorian era, the population grew immensely. At the end of 19th century the population had grown three times bigger in Great Britain! That made wages much lower, because more people were looking for jobs. Many people couldn't afford places to live and had to live on the streets. Slums started appearing in bigger towns. Crime rate was also rising because of this: many homeless child...
Rahvastiku probleemid Sissejuhatus Teema "Rahvastiku probleemid" räägib kõrgest inimeste arvust, inimeste mõjust loodusele ja looduse mõjust inimesele ja inimese tekitatud keskkonna probleemidest. Töö eesmärk on uurida inimeste arvust ja sellest kuidas see nii kõrgeks on kasvanud ja miks? Samuti vaadata ka kuidas mõjutab selline inimeste arv loodust ja leida lahendusi probleemidele ja ka neid analüüsida. Ülesanne on ka vaadata teadlaste poolt tulevikus ennustatavaid muudatusi. Materjalid on võetud internetist ja on kirjutatud faktidena. Populatsiooni kasvamise ajalugu Inimeste arv hakkas tõusma vaikselt aastal 10000 eKr, kui hakkasid tekkima erinevad tsivilisatsioonid. Aastal 8000 oli maailmas inimesi umbes 5 miljonit. Aastani 1000 eKr see eriti ei muutunud, aga aastal 1 eKr oli maailmas 200-300 miljonit inimest. Tänu katkule 6-8 saj Euroopas ini...
ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released ...

Education Education is so multifaceted that it is difficult for me to know where to begin discussing it, or how to prioritize the many factors. Relaying my own experience is easy: I had a standard classroom approach, supplemented by inordinate reading. In only the briefest and least memorable instances did I receive any individual tutoring. Education is commonly thought of as the job of schools. Adults cry "educate our children!" Everyone has opinions about the best way to do the job. It is of urgent importance, and all the numerous factors are much studied, debated, and new (or old) ideas continually tested or retested. Some people say "it's as simple as . . . " and then name their pet peeve or passion. My view is not of an education specialist, but of one who loves sharing what I learn, and owes much to educators. Since I don't have an educational theory neatly worked-out, nor an outline of my perceptions, my intent is to addr...
