In what ways are trees helpful to humans?

they stabilize dust, control erosion, entrap air polluting gases, conserving water and harboring wildlife. Climate control is obtained by moderating the effects of sun, wind, and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is filtered by their branches in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter, we value the sun's radiant energy; Wind speed and direction can be affected by trees.\n\nThere are many and many more , hope i could cover the gist.

In the sources I have listed below are keys to identifying trees.\n\nJust follow the instructions and good luck.

roots anchor plants and uptake water an minerals\nleaves transpiration, resperation and photosynthesis\nstems have a few functions, nutrient transport some are modified for reproduction ie: stolons or rhizomes in trees and woody plants support

Plants are important to us bc they provide the air we need to breathe, we can use them as herbs for healing injuries or health (some are used in medication), we use them for our skin like when its in dermatalogy products & whatnot, & not to mention they are great for making tea & pretty to have around.

The pulp of this fast growing trees is use for making high quality paper.The demand for paper is growing and demand is falling short.Henceforth you have a planting and deforesting programme to sustain the paper industry

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.

The trees are not going to laugh. They will feel relief. More space to grow.

Well, humans need animals and plants for food, raw materials, entertainment and other related functions.\n\nHumans can help plants disperse their seeds and can help feed certain animals.

There are many.  What follows are just a few, and I am certain many people would put them into different catagories:\n\nDeforestation is one.  Humans have cut down many areas of natural vegetation and either replaced it with crops or built cities on it.  Plants return oxygen to the atmosphere from carbon dioxide; they reflect light and adsorb heat from the sun.  Both plants and the soil help adsorb water and pollutants.  The more of the planet we pave, the fewer trees and less soil exist to regulate these functions.\n\nPollution is another.  We dump our trash on land and in the oceans.  We create chemical compounds that wouldn't exist in nature and spread them in the land, water, soil and air.  Some directly effect the health of living things; others effect things like the ozone layer, taking away natural system that protect life on this planet.  We dump the heat from our indutrial processes into the atmosphere and water.\n\nAnd, now, we're relatively certain we are creating enough waste of carbon dioxide, water vapor, and other gases in our atmosphere to trap excess heat in the atmosphere.  Enough of it to warm the entire globe just fast enough that plants cannot adapt.  Fertile zones will change.  Crops may fail.  Livestock (and wild animals) that depend on plants for forage may die.  Areas that we now comfortably inhabit - with suitable climates and drinking water may become desert.  Others may end up under rising oceans as glaciers melt.\n\nWhat can we do about it?  Everyone will likely have a different answer.  As an American, I have to say I am more guilty than many others who will read this.  The average American family (about 5 people) owns 9 internal combustion (gasoline or diesel) engines; in a still developing nation like China, there is one engine for every 159 people. If the Chinese lived like the American, how much soot, smog, waste heat, and carbon dioxide would be produced on a single summer day of driving, lawn mowing, and boating?  How much could our planet take?\n\nThe answers aren't easy.  In the short term, we can use applicance - from light bulbs to computers - that are more efficient in how they use the energy we make.  We can think about how to reuse things to create less waste; or not use them at all. (Seriously, how much of your groceries really need to be double bagged?  And does your produce really need to go in another bag inside that?) We can decide whether we really need to build a new 3 bedroom house for ourselves, or if an older, smaller place can be refurbished to suit our tastes. \n\nBut, ultimately, we use too much.  We burn too many things to create the energy we use.  Period.  But, what are the alternatives?  Deforest vast tracts of land to crate wind and solar farms?  I will leave you to draw your own conclusions, but it seems more and more like the future of our existence on Earth depends on the right answer.

Just like some people said, big tree are more easy to attach wind...people like to talk about BIG people, that's why :)

Of course they do!  they propogate themselves all the time - man just decideds to remove a lot of them in built up areas.  how on earth do you think that trees still survive. Man just plants some to try and make up for all the ones they cut down - trouble is man wants only certain trees in certain places.

Well, those organisms are meant to be there.  Some protected the trees and others don't.  Also some produced fertilizers for the tree.  But then some used the tree as their means of food.  Others also cultivated the soil of the tree.  And most of all, these organisms depended on the tree for oxygen like us as well as energy.

Protect and respect their habitats.  Help wildlife by building a bird feeder, composting, eliminating the use of pesticides and herbicides, etc.  In your garden use plants native to your area - do not introduce plants that are not native - they may disrupt the natural balance. \n\nPossibly one of the best things we can do is stop demanding so much of the world's resources, which, in one way or another, destroys wildlife habitat - increases global warming, destroys the rain forest, etc.  Use cloth reusable shopping bags to carry home groceries.  Buy at bulk food stores using much less packaging materials.  Recycle as much of what we use as possible - glass, soda cans, food cans, plastic containers, newsprint, etc.  Recycle toys, books, games, clothes, etc. by donating them to goodwill or Salvation Army, and shop for things you need at those stores.  Live a simpler, gentler life style.  \n\nHere are a few sites you may like to view.

Oxygen is the byproduct of photosynthesis, which means that trees create oxygen by processing sunlight, water, and carbon dioxide into the simple carbohydrates they need as "food."

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
