Deforestation is a major global problem with serious consequences to the planet. These consequences have a negative effect on the climate, biodiversity, the atmosphere and threatens the cultural and physical survival of life. Deforestation is the permanent destruction of indigenous forests and woodlands. It has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area, so that now indigenous forests cover only 21% of the earth's land surface. The world Resources Institute regards deforestation as one of the worlds most pressing land use problem. It is now so bad that every minute an area of forest equal to 20 football fields is lost. Rainforests cover less than 2 % of the Earth's surface, yet they are home to some 50 to 70 % of all life form on our planet. It has been stated that by the year 2010 the projected loss will be about a million species (that represents about 25% of the estimated diversity of life on Earth). Previous mass extinction's have occurred over millions of years rather than a few decades. The rainforests are the most richest, oldest, most productive and most complex ecosystems on earth and to provide the developed world with goods such as mahogany toilet seats and cheap beefburgers, rainforest destruction is occurring at a frightening rate. In less than 100 years time there may be no rainforests left, and the effects of this both on the gene pool of the planet and on its climate are as yet unknown. Only concerted conservation efforts by all parties, both the owners of the forests and the consumers of the developed world can prevent the long-term loss of this irreplaceable biome... ... middle of paper ... ...

A man named Robert Laughlin once said, "The Earth is very old and has suffered grievously: volcanic explosions, floods, meteor impacts, mountain formation and yet all manner of other abuses greater than anything people could inflict. Yet, the Earth is still here. It's a survivor." Laughlin clearly believes in this quote that the Earth can take care of itself. The Earth has been through worse disasters than just pollution, and extinction of species and plants. Roderick Nash, an environmentalist and activist, says otherwise.

...uring the age of discovery, it is that environments and ecosystems are fragile and can be easily altered with devastating results. Therefore, as humans continue to discover exciting new worlds, either in the darkest depths of the ocean or on the surface of a strange new planet, it is important that we as humans consider the ecological impacts that may result from those discoveries.

It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet. Many people grab a water bottle to go as they head to life as normal, others in developing countries spend their lives searching for water that is rarely found. Even if they do obtain water, it is seldom clean and usually comes with the risk of disease. As more developed countries pay a dollar or so for a bottle of water, others in less fortunate places worship water as if it is gold.
In the world today, trees are being destroyed at a far greater rate than they are being planted. People watch as forests that house many animals are annihilated in a few short weeks as if these forests were meaningless. The worse part is that people rejoice that the trees are being removed, because there will be a new building created soon that will open up opportunities for businesses. The people don’t care that animals lost their homes, or maybe they don’t realize it. The same goes for the loss of native species. Again, is it that people don’t care, or do they not realize the destruction they’re doing? Deforestation has a negative connotation, and it should. This is why people decide to instead say they’re “developing” the land. People are
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. 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, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
First of all I would have to say that yes it has a great impact on our global warming and I will go on to explain to you how it affects our planet. We as a whole have let the dollar get in the way of how our planet is affected, some would say at all costs. It is true we have refineries, car pollution, but most of all deforestation of tropical areas. In the National Geographic Magazine you will come to see and appreciate the facts of how deforestation has affected our nation and has spiraled into global warming. We can look at Brazil’s rainforest that is estimated to be larger than two hundred football fields it will be destroyed before you are even able to read the article at hand (Magazine, 1996-2014). It has been noted that within the past 40 years we have managed to do more damage than what was done in the four hundred and fifty (450) years since the European Colonization even began. That sent chills through my bones when I read that, imagine how much tropical areas have been affected. We have destroyed twen...
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
The forests around the world a supply a plethora of community amenities and commercial goods , nevertheless forested terrain progressively is becoming transformed to accommodate other uses, including cropland, pasture, mining, and urban areas, which can produce superior private financial returns. The wide array of benefits the forest provides that vanish directly tied to deforestation have resulted in several policies drafted with the sole intention to reduce the frequency of deforestation. This paper has two primary objectives. First, this paper will review and summarize both the preceding and current research on deforestation. Second, it will emphasize the significance of future research and development, as well as other solutions needed
The earth is considered as one of the most beautiful planets in the universe. It is the only planet in our galaxy that has enough water to support life. Unfortunately our planet is suffering due to many problems which should be solved before it is too late. The major problems that are facing our world today are population, pollution and animal extinction.

Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
...ws radiation from the sun to expose the surface of the planet, adding to environment changes. If life exists on Mars today, it is most likely hiding beneath the surface. Over the past four billion years Earth has had many rocks blown from the surface of Mars, after much research, scientists say that of the thirty-four meteorites, three have the potential to carry evidence of past life on Mars (Carey, 2006). Researches have gathered evidence and continue to explore for life outside of Earth. Earth has provided these scientists with enough knowledge to understand the components needed to sustain life, therefore any research found is compared to the knowledge already understood about life on Earth. Earth is home to billions of plants, animals, bacteria and all types of living things, it is where human beings have evolved and adapted making this planet our home.
