Forests are important in maintaining biodiversity. Forests take a big role on the air circulation, maintaining water quality, and providing basic human needs and contribute to the culture and recreation. However, there are many problems that could make forest disappeared. The problem for many forests in the world is human. Humans are dangerous for forests because they destroyed forests in such ways as cutting down the trees that provide the ecosystem in their forest, illegal logging that using the timber for factories, farming for provide human food supply, and for agriculture as well. Furthermore, reason for most of cutting down the trees or deforestation is money. Many economists and environmentalists still have different opinions between how they can manage the forests in the future. Economists would think we have enough natural resources or forests that we can use for anything. On the other hand, environmentalists think using too much forests or natural resources for any demands or commodities will impact native animals and plants life. Animals and plants habitat will be extinct soon if we still do cutting off the trees space in the world. First of all, deforestation is one of the biggest issues in the world. There are many problems as the result of deforestation. First impact is pollution gases, these gases will be affect the atmosphere in the world because trees always absorb carbon dioxide gas which is really benefit for trees (National Geographic, n.d., pp. 9). Carbon dioxide is gas that used by trees for supplying their food through leaves. The second problem is greenhouse gases. Trees could be balancing in absorbing greenhouse gas because simply trees could absorb carbon dioxide gas. However, if we cannot saving these ... ... middle of paper ... ...tion. We have many ways to save our trees secure. We can make forests as a recreations or new tourist destinations. Finally we can save the trees either simply we do not have to cutting down the trees or we protecting our trees by monitoring their trees together. Works Cited Lindenmayer, D. B., & Franklin, J. F.

The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
Alina Bradford from Live Science, explained in her article about deforestation and how there are different causes of deforestation such as, selling trees for products such as paper, homes, house hold furniture, and other house products. She also states that other causes of deforestation are making room for agriculture purposes, and to create room for cattle ranching as well. On the downfall though there are disadvantages of deforestation as well too as she explains. One of them in fact is deforestation is contributing to climate change and also the greenhouse effect too as well by emitting a great amount of carbon dioxide (CO2) into the earth’s atmosphere. The effect from that happening is carbon dioxide is a greenhouse which absorbs heat from the sun and doesn’t let it escape into space. As that doing so, the Earth is heating up each year due to deforestation. From that, it will cause global warming and climate change too. There are causes and different purposes for deforestation but there are significant effects that could end up due to deforestation based on Alina Bradford’s
Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .
Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
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.
Deforestation is fast becoming one of the world’s worst environmental/geographical occurring disasters known to mankind, and is due to humankind’s greed, ignorance and carelessness when considering the future of our environment.
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
The rainforest is one of the most diverse places on our planet, containing over half or the world’s animal and plant species. Furthermore, it produces 40% of the world’s oxygen. We humans are cutting down trees, killing all the animals and plant living there, and reducing the size of rainforest.
The Disappearing Rainforests Conserving the rainforest is a global issue of great importance. Tropical rainforests provide a habitat for animals, a unique ecosystem for vegetation, and an abundance of resources for humans, yet they are being destroyed at an astonishing rate. Experts estimate that if these endangered territories continue to be consumed in this manner, no more will be standing in forty years (Rainforest). Examining the social, environmental, and economic costs of the continued destruction of the Earth's tropical rainforests will prove that deforestation for short-term profit is ultimately not viable.

“The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests
Unlike some other places in the world, North America does not have a huge issue with deforestation. We have seen a large increase in forest density and acreage in the past one hundred years. The use of wood helps decrease the CO2 in out atmosphere and it becomes a carbon sink. Trees help take in carbon dioxide and releases oxygen during photosynthesis – which is important right? Right! Deforestation is the second major human cause of global warming as is the pollution of air, water, and viable oils. Disturbance of these resources can disintegrate the food chain which is not only important to animals, but, humans too.
These days, the most controversial problem relates to forests. Forests supply a lot of useful benefits to human beings, for instance, trees absorb carbon dioxide and release oxygen for people to breathe. Forests cover 31% of the land area on our planet (WWF, n.d.). Nobody can reject various advantages from forests. Some people also say that forests are a “green lung” for our planet. According to Food and Agriculture Organization, there are approximately half of the world’s tropical forests which have been destroyed (Szalay, 2013). Forests are lost each and every year. However, some people rely on several benefits of forests to be mercenary. They cut down trees and destroy millions of surfaces to build houses, industrial estates or to serve for human life. That is why, the areas of forests all over the Earth are decreasing dramatically. People have not known that their life is being threatened by destroying forests. Consequently, governments of countries around the world should enact a law about deforestation to protect forests all over the world.
There are many bad things that go on in the world that have an effect on the environments climate and the way it has changed over the years. Deforestation is one these. Deforestation is the act or result of cutting down or burning all the trees in an area (Webster1). The world’s forests could could completely disappear in hundreds of years at the current rate of deforestation. Twelve to fifteen million hectares of forest are lost each year. One hectare is the equivalent to ten thousand square meters.
To overcome this problem person has to get awareness regarding what deforestation is and what are the effects of it if we continue to practice it on the same scale. Actually, trees are the only source to filter the harmful gasses which are present in the atmosphere and can balance the harmful effects of those
