During the summer the sun shines almost 24 hours a day. Summer are usually warm. Average summer temperatures range from 3° to 16°C. TaigaTaiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment. GrasslandsGrassland biomes can be found in the middle latitudes. They can have either moist continental climates or dry subtropical climates. There are two different types of grasslands; tall-grass, which are humid and very wet, and short-grass, which are dry, with hotter summers and colder winters than the tall-grass prairie
winds can blow between 48 to 97 kilometres. The tundra is basically like a desert when it comes to precipitation. Only about 150-250 millimetres of precipitation (mostly snow) fall each year. When water saturates the upper surface, bogs and ponds may form, providing moisture for plants, and breeding thousands of insects that attract many migrating birds. Animals are adapted to handle cold winters and to breed and raise young quickly in the very short and cool summers. Some animals have grown thick fur that turns white in the winter. Others find a place to hibernate during the winter months. Many plants have dark red leaves that allow the plant to absorb more heat from the sun in the cold tundra climate. All of the plants are adapted to sweeping winds and disturbances of the soil. Many plants grow in a low, tight clump - this growth habit helps protect them from the cold and snow. They can carry out photosynthesis at low temperatures and low light intensities
The Charles Darwin Foundation exists to provide knowledge and support to ensure the conservation of the environment and biodiversity of the Galapagos Archipelago through scientific research and complementary actions. The Galapagos Islands remain well preserved as a natural environment in large part due National Park Rules. It is prohibited to transport any live material to the islands, or from island to island, not to take any food to the uninhabited islands, not to feed or touch the animals. It can be dangerous and in the long run would destroy the animals' social structure and breeding habits. The organisms that are in isolation from the human diaspora can evolve in unique ways. World opinion clearly states that Galapagos is of inestimable value to the world's culture and that its environment must be spared destruction.
to take advantage of the nutrients from the decomposing fallen logs. Trees can grow very tall due to amount of precipitation. Temperate Grassland (Prairie)- During a fire, while above-ground portions of grasses may perish, the root portions survive to sprout again. Some prairie trees have thick bark to resist fire. Prairie shrubs readily resprout after fire. Roots of prairie grasses extend deep into the ground to absorb as much moisture as they can extensive root systems prevent grazing animals from pulling roots out of the ground. Prairie grasses have narrow leaves which lose less water than broad leaves. Grasses grow from near their base, not from tip, thus are not permanently damaged from grazing animals or fire. Many grasses take advantage of exposed, windy conditions and are wind pollinated. Soft stems enable prairie grasses to bend in the wind. Taiga- Due to the harsh environmental conditions, not many plants can survive in the taiga biome
The two main types of vegetation are the eucalyptus or gum trees and acacia or wattles. The eucalypts are found all over Australia. There are more than 500 varieties of gum trees in Australia. Australia is the home of some 600 species of acacia. These trees develop smaller, leathery leaves to avoid loss of water. Australia has over 155 million hectares of native forest, about 80 per cent of which are eucalypt. Animal life Australia is a continent sized museum of ancient animals. Anteater and platypus are the two of the strangest animals in the world. They are really reptile mammals. They have hair like cats and dogs, but they lay shelled eggs like snakes and turtles. And they are found only in Australia. Another group of Australian mammals, the marsupials, are less like reptiles than the anteater and the platypus, but they are not highly developed mammals either. The kangaroo and the wombat are marsupials. Their young are born before they are fully developed
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius
the form of air, water and land pollution. If overfishing continues, if pollution continues, many of the species of today will disappear off. Put simply, plastic pollution is when plastic has gathered in an area and has begun to negatively impact the natural environment and create problems for plants, wildlife and even human population. Often this includes killing plant life and posing dangers to local animals. Plastic is an incredibly useful material, but it is also made from toxic compounds known to cause illness, and because it is meant for durability, it is not biodegradable. Plastic pollution does a lot of damage to the world’s ecosystems. Some of the major long-term effects of plastic pollution are: 1. It upsets the food chain because it comes in sizes large and small, polluting plastics even affects the world’s tiniest organisms such as plankton
