Wild animals in danger 11.02.2010 Wild animals in Estonia, like in many other places in the world, are in danger. Forest industry, agriculture and other human activities in the nature, as well as pollution, disturb and even endanger the life of wild animals. Firstly, there is a serious habitat problem because, after pollution or destruction, habitats take many years (sometimes hundreds or even thousands) to grow again. Pollution and destruction change the balance of nature. Each species in a habitat (for example, wood, jungle, marsh or forest) needs and helps the rest. As a result, forests are been cutting down. And what has taken the place of these green, natural places? Houses, farms, cities, streets, roads and factories

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

Environment

I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone"

Protecting endangered species will make a difference in humans life

Protecting endangered species will make a difference in humans' life In the nature of humankind it is natural to hunt animals. However, nowadays hunting endangered species will make humans be just killers, because it is not necessary to kill something just to have a trophy on the wall at home. People can be proud of what they have done, but decreasing the population of a species largely will cause the specific animal breed to go extinct faster than it would happen via natural causes. Therefore, humans should stop hunting endangered species to slow down their extinction, as these species offer balance in the wildlife, are used without purpose in medicine, and may even reduce poverty. Species on the brink of extinction affect us more than we realize. Sure, pandas are cute, and rhinos are fun to look at, but is there anything more to that

ENVIRONMENTAL PROBLEMS

garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. FIND OUT 5 WAYS HOW TO MANAGE WASTE. 5. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and loss of bio- diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. FIND OUT 5 WAYS HOW TO HALT THE LOSS OF BIODIVERSITY 6. Deforestation: Our forests produce fresh oxygen and help in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth

Rare animals

Rare animals Rare Chinese tiger seen in the wild Researchers have confirmed that a wild tiger, photographed by a farmer in the Qinba Mountains of Shaanxi Province, Central China, is indeed that of the critically endangered South China tiger. The South China tiger ­ classified as one of only five subspecies of tiger still alive today ­ is extremely rare, with only an estimated 20 to 30 still remaining in the wild. The wildlife and conservation group WWF says the South China tiger is actually native to the Hainan most forests of south-east China, and because there are so few individuals left, it is regarded by many scientists as being "functionally extinct" in the wild. But a group called Save China's Tigers has been working on a captive- breeding programme and hopes to reach an agreement with China's State Forestry Administration to reintroduce captive-bred animals into the wild.

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would limit the destruction of the rain forests. Intensive farming Advantages ✔ One of the major advantages of this farming technique is that the crop yield is high. ✔ It helps the farmer to easily supervise and monitor the land and protect his livestock from being hurt or hounded by dangerous wild animals. ✔ With the introduction of intensive farming, farm produce, such as vegetables, fruits, and poultry products have become less expensive. It also aids in solving the worldwide hunger problems to a great extent. This means that common people can now afford a balanced and nutritious diet. ✔ Many opine that organic food can be afforded only by the elite strata of the society. Apart from that, large farming spaces are required to cultivate organic crops using natural manure. However,

Temperate deciduous forests, woodlands and shrub

Although the canopy is quite thick, it does allow sunlight to reach the forest floor, which encourages the other layers to grow. The 2nd layer: saplings and shorter kinds of trees The 3rd layer, or understorey: shrubs. The 4th layer: forest herbs, such as wildflowers and berries. In spring, before the leaves develop on the deciduous trees, these herbs bloom and grow quickly while they are getting a lot of sunlight. The 5th layer: mosses and lichens that grow on tree trunks. Lianas such as wild grape, poison ivy, and Virginia creeper climb the trees to flower and fruit high in the forest canopy. Plant adaptations: The plants have adapted so that they can survive in this biome. The leaves of deciduous trees are broad and quite light. This gives the leaves a bigger surface to capture sunlight to help produce food for the plant. This is called photosynthesis. When the weather gets cold, broad leaves are not good for the plant, as they lose too much moisture and get damaged
