The Future is Wild Biome Descriptions 5 million years Mediterranean Basin The Earth is in an Ice Age, a cycle which typically lasts about 100,000 years. Humans are extinct and much of the world’s fresh water is locked up in the huge ice caps that reach as far South as Paris and North as Buenos Aires. On the edges of the ice, animals have adapted to the bitter cold and vicious winters; in the tropics, the rainforest has all but disappeared, and been replaced by a dry savannah. Yet change is in the air – a sudden increase in volcanic eruptions pours greenhouse gases into the atmosphere, the planet begins to warm up, and the melting ice creates massive, devastating floods. Movement of the African and European plates has left the Mediterranean land locked.. Global temperatures are five or six degrees Celsius below the present day. It has brine lakes and salt flats surrounded by karst – dry, ridged limestone. There are deep cracks in the limestone, called Grykes. Mountains rise out of the plains. They were once Mediterranean islands. Otherwise the surface is completely flat and white. The salt flats shimmer. Here and there are lakes of very salty water – ten times the salinity of seawater. In Southern Europe, beyond the icecaps, there are clusters of rowan and birch trees North European Ice Northwest Europe is battered by westerlies so there will be severe blizzards in the winter. Ice sheets cover most of N America and all of Scandinavia, and reach down into Northern Europe. Huge icebergs float in the freezing ocean. The sea level has fallen by 500ft (150m). Winter night-time temperatures are -60oC. Meltwater gathers in the summer. There are cracked and broken rocks all around. Domes, called pingos, rise up where frozen water has pushed up the rocks. North American Desert The drier climate has had dramatic effects on the interior of the North American continent, turning it into a vast, cool desert frequently battered by fierce sandstorms. The desert is as bitterly cold as the Gobi desert once was. It stretches about 2,500 kilometres to the base of the Rocky Mountains. The piercing winds that stir up the sandstorms scour away the soil. A little snow falls infrequently on high ground. Tornados frequently rip across the area. Amazon Grasslands The Amazon grassland lies at the tip of what was once South America. In the Amazon basin, the extensive rainforests are now reduced to a few tiny pockets, surrounded by extensive areas of tall grass savannah with scattered trees. Rainfall is low and the Amazon river has dwindled. In these dry conditions there are frequent bushfires, triggered by lightning or the Sun. The fires cover huge areas at great speed. Grasses rapidly recover from these fires; slow-growing trees are few.

Rainforests coat the land and the atmosphere is rich in carbon dioxide and oxygen. Animals adapt to the damp warmth; insects grow huge, flying insects have metre wingspans, and the world’s biggest creatures walk the Earth. But the Earth itself is restless. Although volcanoes have been active throughout, now, huge eruptions bring the planet to the brink of its worst disaster ever. 100 million years from now; the Earth warms up. The Ice Age has ended. The ice has melted, and sea levels have risen, changing the shape of the coastlines. The continents are still moving. Australia has collided with Asia, pushing up a huge mountain range. Part of Africa has split off and become fused to the tip of Asia. Antarctica has been pulled north by a subduction zone at the bottom of the Indian ocean and now lies partially in the tropics. Instead of snow, ice and penguins, there is now dense tropical rainforest. This rainforest has evolved from whatever plant species made it to the isolated continent first. Similarly, the animals there have radiated to fill all the available niches have evolved from relatively few ancestors, as reaching this virgin continent was so difficult. New species have been developed by adaptive radiation. Antarctica lies in the tropics, with trade winds bringing warm rain all the year round. The forests are temperate and wet. Bengal Swamp The Bay of Bengal is now enclosed, cut off from the open sea by the arrival of Mozambique and Madagascar moving east. What were the Himalayas are eroded to low hills. Water run-off from the mountains has washed fertile sediment into the landlocked sea, making it shallower and rich in nutrients. The sea is a vast, brackish swamp. The water is thick and impenetrable to light. Average temperatures are 40°C. Humidity is 99% all the year round. These greenhouse conditions are ideal for plant growth. Crowded trees and other plants stabilize the mud with their network of roots. Great Plateau The collision of Australia and Asia has resulted in a massive mountain chain, far higher than the Himalayas – 10,000 meters high. The mountains have sharp peaks. Rock compression has thrown up the Great Plateau, the broadest tract of uplands on Earth. The climate of the peaks is harsh, but a higher concentration of carbon dioxide in the atmosphere makes life easier for plants. There is heavy rain on the mountains, and heavy seasonal rain on the plateau. Shallow Seas Shallow seas spread across Northern Europe and Asia, with rocky islands – mountain peaks not yet covered by water. The seas are rich in nutrients and in bright sunlight, ideal conditions for reefs to form. The calcareous skeletons of reef organisms make a solid foundation colonized by more reef plants and animals. The corals are extinct. The reefs are built by red algae; they photosynthesize vigorously in the light. The red algae offer browsing reef animals a protein meal; and in eating this, the animal carries away the algae’s sticky spores.

The slow drift of the continents over the globe has finally brought the landmasses together into one super-continent, and most of the world is covered in a huge ocean. There is now one The Central Desert is a wilderness of sand and gravel, without clouds or rainfall. At night, this desert is as cold as the Earth has ever been. Beneath it, there is a labyrinth of limestone caves. Constant rain on the seaward slopes soaks into the rocks and accumulates in the caves. Average temperatures range from over 50°C in the summer to -30°C in the winter. The only water is from subterranean springs.. large supercontinent, “Pangea II”, the bulk of which is north of the equator. The centre of this continent is a huge extreme desert, with virtually no rainfall. A single world ocean has a major effect on weather patterns. Water travels westward around the equator, being warmed by the Sun as it goes. Heating the ocean leads to frequent and very strong hurricanes. The sea is whipped up by these frequent hyper-canes. But the resulting rain does not travel far inland instead falling on a coastal mountain range. In today’s world there are continents in the way of this equatorial current, that deflect it to the north or south before it has chance to get too warm. The rotation of the Earth has slowed, adding an hour to the day – now 25 hours. Global Ocean The Global Ocean has a huge anti-clockwise current circulating around the southern hemisphere. Life can migrate easily in this powerful current. Because of this powerful current, there is little water movement between north and south. As a result, there is a steep temperature gradient between high and low latitudes. The single ocean supports complex food chains and highly-evolved species. A mass extinction has affected life on land and in the seas. Clouds of ash and an increase in acidity killed the plankton in the surface water. As the ocean food chain collapsed many bony fish died out. Their place was taken by surviving creatures from the deep. Rainshadow Desert The Rainshadow Desert is close to the huge peaks of this volcanic mountain range. The moisture rich clouds crossing the Earth rise over the mountains, losing water as they go and starving the land behind of moisture. The hyper-canes provide high humidity; they also supply food in the form of sea creatures whipped from the surface waters and dumped in the desert. Northern Forest Along latitudes about 30 to 60 degrees north, the prevailing winds are westerlies that bring huge amounts of rain to the northwest coast of the continent. This creates extensive, lush areas of temperate forest, something similar to the rainforest of northwest USA but much, much more extensive. Constant rain from saturated onshore winds, frequent westerly storms and little sunshine causes rain to fall relentlessly on the north-western region of “Pangaea ll”. The conditions are warm and humid with an atmosphere rich in carbon dioxide. These hothouse conditions, ideal for plant growth, have led to a vigorous forest, teeming with life. The continuous torrential rain has made great rivers, lakes and swamps. The tallest trees are conifers, growing to the same height as the redwoods that have dominated the region since the Triassic. Flowering plants are rare in the forest; only lichens – symbiotic associations between algae and fungi – grow everywhere. In the moisture of the forest, they have grown to tree size. The low level of the forest is a tangle of lichen trees. Their trailing feathery structures absorb moisture and photosynthesize. Their spores, bursting from sacs as animals brush by, are easily distributed.
