Science Current Event: World's Biggest Trees Dying (2012)
World’s Biggest Trees Are Dying

Many of the world’s oldest trees, that are 100-300 years old, are dying. This is a trend happening worldwide. It’s happening in forests, savannahs, woods, mountains, cities, etc. The cause is human domination. We’ve been killing off these trees with pollution, deforestation, and other causes. This could really affect the world because other plants and animals depend on these trees for life, whether it be for food, shelter, or other needs. Large, old trees provide shelter for up to 30% of animals and birds in some ecosystems. Therefore, if these trees die out, we’d be looking at other species dying out too. It’s kind of embarrassing to see what humanity is doing to the other species of the world.

The largest living organisms on the planet, the big, old trees that harbour and sustain countless birds and other wildlife, are dying.
A report by three of the world's leading ecologists in today's issue of the journal Science warns of an alarming increase in deathrates among trees 100-300 years old in many of the world's forests, woodlands, savannahs, farming areas and even in cities.
"It's a worldwide problem and appears to be happening in most types of forest," says lead author Professor David Lindenmayer of the ARC Centre of Excellence for Environmental Decisions (CEED) and Australian National University.
"Large old trees are critical in many natural and human-dominated environments. Studies of ecosystems around the world suggest populations of these trees are declining rapidly," he and colleagues Professor Bill Laurance of James Cook University, Australia, and Professor Jerry Franklin of Washington University, USA, say in their Science report.
"Research is urgently needed to identify the causes of rapid losses of large old trees and strategies for improved management. Without… policy changes, large old trees will diminish or disappear in many ecosystems,

    To understand why deforestation is such a pressing and urgent issue, forests must first be given credit for what they bring to global ecosystems and the quality of life that all species maintain. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath by trapping carbon and other particles produced by pollution. Because of the deforestation of the rainforest, nearly half of the world 's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century…

    The overuse of natural resources due to increased demand and also the removal of ecosystems due to population growth have had a large negative impact on the environment. Extensive deforestation has occurred world-wide with the logging industry being fuelled by the need for disposable products. 11 million acres a year are cut for commercial and property industries. In Australia 90% of native forest wood are exported, destroying Australia’s natural heritage. About one half of the forests that covered the Earth are gone. Each year, another 16 million hectares disappear. Deforestation is expanding and accelerating into the remaining areas of undisturbed forest. In Indonesia, powerful families allied with the government rulers control large and highly valuable timber concessions. These forests are being rapidly logged, at enormous…

    Every human activity has a particular effect on objects surrounding his or her environment, be it physical, mental, or social. But notably, the most evident might be the effect of human activity on global warming. Global warming is quickly becoming a major topic of concern worldwide, and has been stirring up controversy everywhere with its adverse effects seen all over the world. It causes rise of the temperature, leading to – among other things - melting of the polar ice and glaciers, increase in sea level, and extreme weather events. Its effects can also be felt in the form of natural disasters like drought, floods, and tornadoes. Of recent, we have experienced very devastating natural disasters like the Tsunami that affected many parts of Asia in 2005, Hurricane Katrina, numerous tornadoes in the United States, and the recent earthquakes in Haiti and Japan. All these are due to effects of global warming. Research evidence by scientists and opinions polls conducted by credible pollsters indicate that the major causes of climate change are human activities and this paper tries to evaluate the impact of human activities on global warming and how climate change has in turn affected the very same humans whose activities cause global warming.…

    Forest has been defined as “An area with a high density of trees. These plant communities cover large areas of the globe and function as carbon dioxide sinks, animal habitats, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of our biosphere ". Forests are the storehouse of natural resources, without which the very sustenance of human population would be under threat. Yet forests have been the first to bear the brunt of civilization. Growing human population has consistently put pressure on the forest cover.…

    Expanding population, industrialization and need of land for development of expanding cities, conversion of land to agriculture, urban sprawl, infrastructure development, etc. has led man to cut down forests recklessly . Not only are the forests home to a large number of animals, trees are also an important component of the water cycle. The roots of plants hold the soil together and prevent soil erosion. The global forest cover has shrunk to half its area in the last 11,000 years. Deforestation at such alarming rate has been a cause of constant worry for environmentalists the world over.…
