• 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, leaving less than 1% of the world's freshwater, or about 0.003% of all water on Earth, readily accessible for direct human use. • According to the Global Outlook for Water Resources to the Year 2025, it is estimated that by 2025, more than half of the world population will be facing water-based vulnerability and human demand for water will account for 70% of all available freshwater.
2 MINUTIT. I'm going to talk about water consumption and about the importance of the water. I've chosen this topic because water is our most important resource and I'm also very worried about how little there is left of it. At the moment a bottle of water costs less than an euro, but within the next 10 years the very same bottle may cost 5 to 10 euros, if we don't conserve and protect our fresh water supply. The thing is, we have enough sea water, but it's the freshwater we lack of. Water covers over 70% of the Earth, but just 3% of it is fresh and less than 1% is the water that is available and we can drink. The amount of freshwater is rapidly decreasing. The water we have now is all we will ever have, we cannot produce anymore. Moving on to the importance of water. There wouldn't be any life on Earth without water. Water cools the Earth and all plants, animals and humans need clean water to survive.
Most of Estonia's many islands belong to the West Estonian archipelago. The largest islands are Saaremaa with 2671 sq km, Hiiumaa with 989 sq km and Muhu with 200 sq km. The sea between these islands and the Mainland Väinameri is very shallow (less than five metres deep on average) and rich in shoals. The water of the Baltic Sea is brackish. Its average saltinity is only one fourth of that of the sea in general. Thus, most Estonian freshwater fish (about 30 species) also inhabit the sea. There are some 1450 lakes in Estonia (6.1% of its territory). The two largest of them are Lake Peipsi (the fifth largest in Europe) at 3555 sq km and Võrtsjärv with its 270 sq km area. About 1440 vascular plant species grow in Estonia, while ¾ of the total number of species are found in the coastal lowlands and islands. There are 82 species of fish living in Estonia, which are hard to divide into freshwater and sea species.

vulkaanilisi gaase, et sel on Maa kliimale väga suur ja pikaaegne mõju. 6.This detailed astronaut photograph depicts the summit caldera of the volcano. The huge caldera is 6 kilometers (3.7 miles) in diameter and 1,100 meters (3,609 feet) deep. It formed when Tambora's estimated 4,000-meter- (13,123-foot) high peak was removed, and the magma chamber below emptied during the April 10 eruption. Today the crater floor is occupied by an ephemeral freshwater lake, recent sedimentary deposits, and minor lava flows and domes from the nineteenth and twentieth centuries. Layered tephra deposits are visible along the northwestern crater rim. Active fumaroles, or steam vents, still exist in the caldera.

It all depends on the environmental consciousness of farm owners. Many tend to discharge wastewater directly into rivers, wastewater treatment is expensive.” Kathryn Arnold, at the University of York, who has been researching reasons of wildlife decline said: “With thousands of antibiotics in use globally, they have the potential to have potent effects on wildlife and ecosystems.” Research published in 2014 revealed that in the last 40 years, in freshwater habitats, where drug residues are most commonly found, the research found 75% of fish and amphibians had been lost. That shows clearly the harmful effect of the antibiotics to aquatic animals. In my opinion, the authors have succeeded with their articles. Firstly, I really liked that all of the articles had specific statistics and I appreciate it. Secondly, all the examples were apposite and points were clear. I personally find the topic very actual and the problems need even more attention.

It borders in the south with The United States and it's surrounded in the west by the Pacific Ocean, in the east by the Atlantic Ocean and above by many smaller bays, but is also borderedd with Alaska in the north-west. To the north of Canada is the broad Canadian Shield, an area of rock scoured clean by the last ice age, thinly soiled, rich in minerals, and dotted with lakes and rivers. Canada by far has more lakes than any other country and has a large amount of the world's freshwater. You can see more lakes in the south eastern part, on the U.S.A's border, including the famous waterfall Niagara Falls. The eastern areas of Canada are occupied by the Saint Lowrence Lowlands. The Saint Lawrence River widens into the world's largest estuary before flowing into the Gulf of Saint Lawrence. In northwestern Canada, the Mackenzie River flows from the Great Slave Lake to the Arctic Ocean. Northern Canadian vegetation tapers from coniferous forests to tundra and
During the war Estonia was occupied b yNazi Germany in 1941, then reoccupied by the Soviet Union in 1944. Estonia regained independence in 1991 after the collapse of the USSR and joined the European Union in 2004. Rivers, Lakes, Waterfalls Estonia is a country of thousand of lakes. In the Estonian territory there are about 1200 natural lakes whose water area exceeds 1 ha. The largest of these is Lake Peipsi, which is the fourth largest freshwater lake in Europe. Most of Estonia's lakes are small and are found in the south of the country. Larger lakes such as Lake Peipsi and Lake Võrtsjärv are rich in fish. One can find rare species of fish such as the lake whitefish and the Peipsi smelt in Lake Peipsi. Võrtsjärv is famous for its catches of pike-perch and eel, which are regarded as a delicacy. There are also many rivers in Estonia, but only ten of them are longer than 100 kilometres
you can come across types of primeval forest cover, which have long ago disappeared from other parts of Europe. Examples of such primeval forests are the Järvselja forest in Tartumaa County and Poruni in Ida- Virumaa County. Meadows in Estonia are rich in different species much more so than in Western Europe.

river spanning 7 countries provides an estimate of the abundance of the two species, and essential information on the most serious threats they face, the current state of their habitats and potential conservation strategies. Communications director for WWF Colombia Julio Mario Fernández said one early conclusion scientists could draw was that river dolphins in the Amazon were doing better than those in the Orinoco. "This is the first phase of a wider programme to preserve freshwater cetaceans in these areas," he added. Fresh water dolphins are among the most threatened aquatic mammals in the world. The situation is most dire in Asia, where the Yangtze river dolphin is probably extinct and the Indus river dolphin faces a high risk of becoming extinct. Fernández said it was essential to act now before South America's dolphins go the same way. The pink river dolphin, or boto, is already classified as vulnerable by the IUCN's Red List of Threatened Species

Fishery resources Capture fisheries resources are highly diverse. FAO landing statistics refer to about 2 500 species or group of species most of which are finfish. By far the most numerous fish species, and those most important to aquaculture and fisheries, are teleosts, or bony fish, which in the sea extend from small "grazing" species such as anchovy to large active predatory fish such as tuna. A similarly wide range is also found in freshwater, with the most important species from a production point of view belonging to the carp family. These account for over half the total of inland waters fisheries production. Marine capture fisheries resources are usually considered close to full exploitation worldwide with about half of them fully exploited, one quarter over exploited, depleted or recovering from depletion and one quarter only with some capacity to produce more than they presently do

of Great Britain and Norther Ireland. The UK is situated north-west of the European continent between the Atlantic Ocean and the North Sea. The UK consists of England, Wales, Scotland and Northern Ireland. Its highest point is Ben Nevis in Scotland followed by Snowdon in Wales. The Severn is the longest river in the United Kingdom. Other important rivers are the Trent, the Mersey, the Tyne, etc. Lough Neagh which lies in the centre of Northern Ireland is thr UK's largest freshwater lake. The climate in the UK is variable. The weather changes so frequently that it is difficult to forecast. It is not unusual for people to complain that the weathermen were wrong. Fortunately there is no extreme weather conditions, it is never very cold or very hot. The first inhabitants were Iberians and Celts who settled on the land and were often at war with each other.

In the north The Gulf of Finland separates Estonia from Finland. The Gulf of Riga is situated to the south-west. Estonia has more than 1500 islands. The biggest ones are located to the west. The four biggest islands are Saaremaa, Hiiumaa, Vormsi and Muhu. The highest point in Estonia and also in the Baltic region is Suur Munamägi. It is 318. above sea level. Estonia is a country of a thousand lakes. The Largest one is Lake Peipsi which is also the fourth biggest freshwater lake in Europe. Lake Peipsi and Lake Võrtsjärv are rich in fish. Estonia has many rivers but only nine of them are longer than 100km. The most important ones are Pärnu River and Emajõgi River Climate Estonia lies in the northern part of the temperate climate zone and in the transition zone between maritime and continental climate. Because Estonia is continuously warmed by the Gulf Stream it has a milder climate despite its northern latitude. Northern latitude means long
At the heart of the continent is Uluru (named Ayers Rock by the colonial settlers), a monolith of great spiritual significance. This great rock reaches 348 metres tall and measures nine kilometres at its base. Take a guided walk around Uluru or visit the Aboriginal Cultural Centre to find out more about the history of the area. Sydney Sydney is well known for its seafood including Balmain Bugs (a small local freshwater lobster creature), Crayfish from Tasmania, Barramundi (large white meaty fish) and John Dory (smaller white fish). There are also specialties from other areas such as Queensland Mud Crab, and Coral Trout from the Great Barrier Reef, and Ocean Salmon and Trout. Known for its famed opera house and harbor, Sydney also boasts an incredible bridge, great parks, delicious food, lots of free stuff to do, and amazing surfing.

About half of Australia's 230 mammal species are marsupials. As well as meateating Tasmanian devils, possums, bandicoots and ofcourse kangaroos, wombats and koalas. The largest meateating marsupial Tasmanian Tiger is probably extinct. Most of Australian native animals move around at night. But the birds which are very colourful are easy to see. There are about 750 species ofbirds in Australia. Two types of crocodiles, the saltwater crocodile and the freshwater crocodile can be found in the north. The dingo or the native dog is not really an Australian native. It has brought from Asia around 3500 years ago. The dingo is an efficient sheep hunter. To protect sheep the dog fence was built in 1964. Climate Australia is the driest continent in the world except Antarctica. It has very low average rainfalls. About 70 per cent of the country is arid or semiarid and cannot support agriculture. The north part of the countrygets about 300

Some rare and exotic species include the flying squirrel, Saimaa Ringed Seal and the Arctic fox, which is considered the most endangered. The Whooper Swan, the national bird of Finland, is a large Northern Hemisphere swan. The most common breeding birds are the Willow Warbler, Chaffinch and Redwing. Of some seventy species of freshwater fish, the northern pike, perch and others are plentiful. Salmon remains the favorite of fly rod enthusiasts. The endangered Saimaa Ringed Seal, one of only three lake seal species in the world, exists only in the Saimaa lake system of southeastern Finland, down to only 300 seals today. It has become the emblem of the Finnish Association for Nature Conservation. Due to hunting and persecution in history, many animals such as the Golden Eagle, Brown
The Scottish flag has a white cross on a blue background. It is also on the Union Jack. Northern Ireland is the smallest part of the UK as it only covers about 5500 square kilometres. About half of the 1.7 million inhabitants live in or around Belfast, the capital, in the eastern coastal region. The centrepiece of Northern Ireland's geography is Lough Neagh, at 151 square miles (392 km²) the largest freshwater lake both on the island of Ireland and in the British Isles, and the third largest lake in Western Europe. A second extensive lake system is centred on Lower and Upper Lough Erne in Fermanagh. Northern Ireland don't have an official flag any more nor a coat of arms. Due to the division of the population along ethnic, religious and political lines, a wide variety of flags can be seen flying from lampposts and private houses across Northern Ireland. Government

The Highlands are generally mountainous and the highest elevations in the British Isles are found here. Scotland has over 790 islands, divided into four main groups: Shetland, Orkney, and the Inner Hebrides and Outer Hebrides. There are numerous bodies of freshwater including Loch Lomond and Loch Ness. Some parts of the coastline consist of machair, a low lying dune pasture land. Highlands and Islands lie to the north and west of the Highland Boundary Fault, which runs from Arran to Stonehaven.

The largest of them are Saaremaa, Hiiumaa, Muhu and Vormsi. There are over 1,400 lakes in Estonia, biggest being Lake Peipsi and Lake Võrtsjärv, while the deepest is Rõuge Suurjärv. The two longest rivers are the Võhandu and the Pärnu and the widest is Emajõgi. About 50% of the country is covered by forests while wetlands cover 30%. The landscape of Estonia, through covering a small area, is varied and unique. Lake Peipsi is Estonia's largest lake and Europe's fourth largest freshwater lake. 5. Symbols The flag The Estonian blue-black and white national flag was originally the flag of the Estonian Students' Society and was consecrated in Otepää Church in 1884. Today there is a memorial plaque on the church wall commemorating the event. The Flag Museum, opened in an annex in 1996, attracts tourists who take an interest in the history of the flag.

Today Australian marsupials are dying out. Dogs, cats, and rabbits brought to Australia by men are rapidly destroying the gentler marsupials. Some day there may be nothing left of the ancient animals. Australia has around 800 species of birds, 400 of which are unique to this country. There are 55 species of parrots in Australia, and the birds are as numerous as they are colourful. Two types of crocodile, the saltwater and the freshwater crocodile are found in the north. The dingo, or native dog is not really an Australian native. It was bought from Asia around 4000 years ago. The dingo is an effective hunter. To save their sheep from dingo attacks, farmers built many fences to keep the dingo out. These fences didn't work so in 1946 the government built a single fence which stretched 5400 km from Great Australian Bight in South Australia to near the Queensland coast. The single fence worked better.
About half of Australia’s 230 mammal species are marsupials. As well as the meat-eating Tasmanian devil, possums, bandicoots and of course kangaroos, wombats and koalas.

8. Mille alusel eristatakse bioome? Bioom ehk makroökosüsteem on geograafiliselt piiritletav ala mingi taimkatte- ja ühtlasi ka kliimavööndi piires. Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms,[1] and are often referred to as ecosystems. A fundamental classification of biomes is: 1. Terrestrial (land) biomes 2. Aquatic biomes (including Freshwater biomes and Marine biomes) Biomes are often known in English by local names. For example, a temperate grassland or shrubland biome is known commonly as steppe in central Asia, prairie inNorth America, and pampas in South America. Tropical grasslands are known assavanna in Australia, whereas in Southern Africa it is known as veldt (fromAfrikaans). 9. Mis on ökotüüp? Ökotüüp e ökoloogiline rass sarnaselt kohastunud organismid ühe liigi piires (nt lillakas turbasammal)

congregate along the Iberian Peninsula since it is the closest stopover between northern Europe and Africa. Six hundred bird species occur in Portugal (either for nesting or during the course of migration), and annually there are new registries of nesting species. The archipelagos of the Azores and Madeira are transient stopover for American, European, and African birds, while continental Portugal mostly encounters European and African bird species. There are over 100 varieties of freshwater fish species, varying from the giant European catfish (in the Tagus International Natural Park) to some small and endemic species that live only in small lakes (along the western lakes for example). Some of these rare and specific species are highly endangered because of habitat loss, pollution and drought. Upwelling along the west coast of Portugal makes the sea extremely rich in nutrients and diverse species of marine fish; the Portuguese marine waters are one of the richest in the world
