Why do we need a forest ?

Climate balance is one big reason, but there are others. \n\nForests are part of oxygen and carbon dioxide balance, because they absorb net carbon dioxide and produce net oxygen.  Also, they increase water evaporation which increases cloud cover (which tends, amongst a whole bunch of complex effects, to reduce global temperatures by reflecting sunlight) and produces rainfall.\n\nNorth Eastern Brazil is regularly in a state of drought-stricken poverty.   The deforestation of the Amazon basin to the West may be partly to blame.\n\nForests encourage a very wide range of species to exist.   Biodiversity might be a positive benefit to climate balance, because the huge range of biological activities that the different species engage in makes it more likely that stabilising feedback loops will emerge and be robust.\n\nEvolution is very intense in tropical forests in particular, and that makes those areas more likely to produce unusual chemicals.  That's why people hunt rainforests for plants with which to make new drugs.\n\nForests stabilise soil and slow down rainwater, preventing downstream erosion and soil depletion and benefiting agriculture.\n\nFinally, life is sh*t when there are no trees.

RE: your request "need to know what are some future plans of the redwoods"\n\nRedwoods or other trees don't make plans, but I know what you meant. :)\nLook at this for a starter: http://redwoods.bullhorn.org/news/20000717/internet_sem.html\n\nThis is the kind of answer your teacher is probably looking for.  Big corporations raping the forests, etc.  While a lot of that line of thought is true, it is not usually as bad as they claim.  You might gently suggest there is some sign of hope by using the idea of "sustainablility" of the forests (IE, replanting redwoods as they are cut, similar to how the pine forests in the southeast have been placed millions of acres of land in regrowing pines as a method to continue to provide us with building wood and paper producst). \n\nFind more interesting information just by typing in your question into Google and read all you can.  You never know, you might find it interesting.

All of them.\n\nLiving in a "National Forest" is no big deal at all.  In fact, huge amounts of most forests are in private hands.  Simply find some land that rests inside of the forest and buy it.\n\nNational parks are a bit different.  But yes, most of them have at least some of the land in private hands.\n\nMost also have cabins and campgrounds that you can stay in.  If you have the money, you can simply rent a cabin in one of them forever.

It helps with the environment in many different ways such as increasing the annual rainfalls, keeping the environment cool, and decreases the ratio of wind evaporation which saves the atmosphere from becoming dry. This provides immunity to inhabitants of such areas from chest and respiratory diseases. The tree helps in stabilizing canal banks and preventing soil erosions

I am guessing you are asking about environmental conservation.  Certain natural resources are limited.  If we use them wisely, then they will be available for a longer period of time.\n\nThere is a limited amount of oil in the ground, for example.  If we use it up, we will not have it to heat homes and power vehicles.  One way to conserve, would be to find other ways to heat homes and run motors.  Solar power, wind power and now biofuel are ways in which people are trying to do this.  Another way to conserve would be to use less heat in our homes and find other ways of travel, instead of cars.\n\nFrom my point of view, the most important environmental resources are clean air and clean water.  If you pollute those resources then nothing will live - people, animals, plants - we all need clean air and water.\n\nTrees help clean the air, which is why it is important to have forests and parks, so the trees can consume the carbon dioxide we breathe out while they breathe out the oxygen we breathe in.

you get more air from the trees, it takes away carbon dioxide, and it protects the ozone from further damage.

Because I care about the land.  I care about our wildlife. I care about the people here--who do not deserve less in needs to give others more in wants.\n Guess you could care less of either if it gets you what you want. Pretty selfish.

When done right, selective logging helps to open the forest up and let more botanical species thrive.\n\nBy halting it, you run the risk of increased, and more dangerous fires, such as those seen n recent times in the western USA.  \n\nEither way you look at it, you're damned if you do and damned if you don't

One of the main reasons for global warming is an increase in greenhouse gases, such as CO2.  With less greenery and forest, the air does not have a chance to clean itself, since plants absorb CO2 and release O2, which we need to survive.  The urbanisation of rainforests means that they are being cut down, exacerbating this effect.

A certain amount of our oxygen comes from trees.  One article claims that 70% comes from the trees in the rainforest.  Of course a conflicting article says that 30% of our oxygen comes from trees.  I'd be interested to know the truth.  (I believe the truth is that most of our oxygen comes from ocean plants.)  The fact is, though, that oxygen comes to us through photosynthesis.  http://en.wikipedia.org/wiki/Oxygen_cycle  Trees are one source of the oxygen we breathe on this planet.   Bacteria, algae, and all other plants also contribute.\n\nThere are a few things that come to my mind when discussing the preservation of the world's forests.  Trees are a renewable resource.  If harvested responsibly, the older and unhealthy trees are taken, and the younger, healthier trees are left to grow and reseed the forest.  In the long run, you end up with healthier forests that continue producing trees at a sustainable rate.\n\nWhen developing an area, land may be cleared of trees and forests may be destroyed.  In that case, the forest will not reseed and grow back.  That part of the forest is gone.  Many areas have laws about the size of a piece of land that one can clear-cut, although some do not.  There are no laws providing for the contribution of trees to another piece of land as a way to reclaim the forest lost to development.\n\nIn the case of coffee growers, etc, land is clear-cut to make fields for growing the more lucrative crops.  While no one can really blame anyone for wanting to make money, I believe this type of deforestation is destroying the rainforests.  As long as individuals are allowed to own land, there will be arguments about how much authority the private citizen has over land use.\n\nSome forests are lost naturally to fire.\n\nThere are small things that a person can do to help slow the deforestation process.  First, manage the land that is in your care well.  If you own land, be aware of the health of your trees.  Are you considering logging off your back forty?   Be responsible.  Choose a responsible forester and loggers that respect the remaining trees.  Smaller logging operations may be more apt to manage the project with less damage to the trees that are to be left.  Remember, the logger makes money off your trees, too.  Be sure you pay attention to the project and understand what is being cut.  In many cases, a forest can be logged again in 10 years.\n\nIf you are developing an area for a house lot, carefully consider what it is that you really wish to cut?  Do you really want to clear all ten acres?  Would you have just as beautiful a view and maybe a prettier landscape if you leave the nicer hardwoods?  Remember the animals that a small softwood cluster would attract.  Think about the shade that trees provide and the colors of the autumn foliage just before winter covers that land.  Make your choices wisely, and remember the benefit of the trees to the rest of the world -- even those who will never see your lovely new home.\n\nIn the case development by business, support those business that care for the land.   If you spend your money in support of responsible businesses, if everyone does, then it will be more lucrative for that business to continue to be responsible.  If it appears over the course of doing business that no one cares, the people operating the business may decide it isn't worth the effort.  Responsibility has rewards, but it also has a price.  Support responsible businesses.\n\nLikewise, consider the rainforest.  If you are concerned with the deforestation of the rainforest, as we all should be, consider giving up some of the products that you enjoy that have been harvested from land that was once rainforest.  Although that forest is already gone, if there isn't demand for those products, if consumption falls, that act could lessen the "need" to cut more forests.  Seriously, I drink a lot of coffee and continue to do so.  I'm not sure what sort of a dent this on

Deforestation is the loss or continual degradation of forest habitat due to either natural or human related causes. Agriculture, urban sprawl, unsustainable forestry practices, mining, and petroleum exploration all contribute to human caused deforestation. Natural deforestation can be linked to tsunamis, forest fires, volcanic eruptions, glaciation and desertification. The effects of human related deforestation can be mitigated through environmentally sustainable practices that reduce permanent destruction of forests or even act to preserve and rehabilitate disrupted forestland.

A forest has lots of wood, a wood doesnt have lots of forests

Develop ways that the people who live there can earn a livelihood without damage to the forest.  Ways where they work to protect the forest and yet earn a living.

a tree that grows money... would end world poverty!\nwould plant them everywhere and let them grow wild.

I still believe that most of must wants to preserve the nature, however it is the conflict of interest that is preventing us from doing so,  because of the development and modernization of our world some natural habbitat are being destroyed. We focus more on modernization thus conservation of nature is being taken for granted.

First, I am not a scientist but a scientfic researcher. It's important to know what animals eat the seeds or fruits of flowering trees to deduce it's role in a given ecosystem. It's relationship to the other living organisms in it's environment is very important. It's also imortant to know what animals very existence hinges on the trees continued existence in the ecosytem. In other words, as trees get chopped down and various animal species that depend on the trees start to die, that is then a useful barometer of the trees role in the ecosystem.
