What are your opinions about illegal logging?

my opinions about illegal logging are :

  • illegal logging is dangerous because if we can't stop illegal logging it will bring many calamities like landslides and floods.
  • it can also damage our mountains.
  • if we can't stop illegal logging we can't feel the fresh air that can only be produced by the trees.

What is deforestation?

Deforestation is people cutting down whole forests of trees, and making it even less likely for humans to survive. Trees supply oxygen, absorb carbon dioxide, and hold down the soil from washing away or making landslides.

The destruction and cutting down of forests is often done to clear land for farming, mining, roads, and grazing of cattle. That causes increased atmospheric CO2 levels, a factor in global warming.

The Cutting down and clearing of trees

The action or process of clearing forests_ also _The state of having been cleared by forests.

Verb. To Clear of Forests or trees

.

The conversion of forested areas to non-forested lands.

e.g. Cutting down a forest to make pastures.

the cutting down of trees is called deforestation

Deforestation means clearing of forests and using that land for other purposes.

defforestation is cutting of trees.

deforestation is when rain forests get destroyed and ruined
1. The state of being clear of trees

2. The removal of trees

Deforestation occurs to create open space for urban or agricultural use.

What can you do about tourists using natural resources?

Tourists pollute waterways and oceans, they damage the environment.

What we can do about it:

By governments putting restrictions on holiday resorts and developers, they can prevent resorts being built on wildlife habitats, and also close down or limit the size of resorts already built on wildlife habitats.

  • There must be no pollution into waterways and oceans.
  • Garbage and sewage must be collected and recycled as much as possible.
  • Tourist movements into natural areas must be limited so the numbers don't do any damage to the environment.
  • Building must blend into the natural environment.
  • There must be no illegal deforestation (eg, cutting down rain-forests to build a golf course).
  • New resorts and gardens must not put too great a demand on water and other natural resources.

By governments putting restrictions on holiday resorts and developers, they can prevent resorts being built on wildlife habitats, and also close down or limit the size of resorts already built on wildlife habitats.
You can't stop tourists from using natural resources. Trying to do that will end your tourist industry on the spot. People are going to use resources no matter where they are. What you want to do is make accommodations for tourists as green as possible while maintaining enough comfort for tourists to enjoy their stay. Make sure that hotels are using the most energy efficient products, and are built to minimize energy waste. Transportation systems should do the same.

How much rainforest is destroyed every year?

The Food and Agriculture Organization of the United Nations (FAO) found that tropical deforestation rates increased 8.5 percent from 2000-2005 when compared with the 1990s.

All round the world tropical rainforests lost 10,240,000 hectares (25 million acres) every year between 1990 and 2005.

That's:

  • 10,240,000 hectares (25,000,000 acres) in one year. Or
  • 197,000 ha (481,000 acres) in one week. Or
  • 28,000 ha (69,000 acres) in one day. Or
  • 1172 ha (2861 acres) in one hour. Or
  • 19.5 ha (48 acres) every minute.
  • 0.33 ha (0.8 acres) every second.

That's about 36 football fields of rainforest lost every minute.

An American Football field measures 0.53 ha (1.32 acres).

Countries annually losing the most rainforest 1990 and 2005:

  • Brazil: 2,974,867 ha (7,351,000 acres) per year
  • Indonesia: 1,447,800 ha (3,577,000 acres)
  • Papua New Guinea: 266,600 ha (660,000 acres)
  • Bolivia: 135,200 ha (334,000 acres)

What is causing deforestation?

The most common cause of deforestation is human removal of trees for lumber and/or to change the use of the land to farming. This was common in the early settlement of the US. In Brazil, and other rain forest areas, this change is less than ideal since the soil is not suitable for successful agriculture.

Global Warming

How does deforestation contribute to global warming?

Forests through photosynthesis absorb carbon dioxide (CO2) and release oxygen. The timber of the trees also sequesters carbon. Deforestation means the timber may be used and eventually converted to carbon dioxide, or left to rot, which also means that it is converted to carbon dioxide, a greenhouse gas responsible for global warming. Similarly the green leaves no longer act as carbon sinks to suck in CO2. Either way, deforestation contributes to the global warming process.

A:Deforestation = fewer trees

Fewer trees = more CO2

More CO2 = Enhanced Greenhouse Effect

Enhanced Greenhouse Effect = Global warming

A:Deforestation is one of the main causes of greenhouse effect because as we cut trees, the water cycle gets disturbed causing less rain and the amount of oxygen decreases while the amount of carbon dioxide increases. When the carbon dioxide increases, more heat radiated by earth is trapped on earth, making it warmer than usual, thus increasing global warming and becoming the main cause of green house effect. A:Global warming is caused by an elevation in the greenhouse gases that halo our planet. Atmospheric gases such as water vapor, CO2, methane, and ozone are responsible for impeding the loss of heat away from the Earth. The concentration of these particular gases directly dictate the universal temperature found on Earth.

The effects of global warming can be further exacerbated by deforestation because the removal of densely forested areas decreases the number of the CO2 consuming vegetation.

Photosynthetic organisms, such as plants, undergo a "carbon fixing" cycle which utilizes atmospheric carbon dioxide and synthesizes it into metabolic intermediates (such as carbohydrates). Indirectly, deforestation disrupts the delicate balance between the carbon dioxide produced and consumed. An increase in the concentration of carbon dioxide, along with other greenhouse gases, leads to an increase in the global temperature.

The issue is further worsened if these trees are used for fuel and not replaced. Forests' primary function is not to remove CO2 (that is a minor player in that process) but to be a carbon sink, or storage unit for carbon.

Total carbon intake, in terms of percentages, of forests is not high, but does contribute to the overall intake of carbon. Our Oceans are the major player in carbon absorption.

Selective cutting can actually lower an overall carbon emission, by taking wood that would otherwise rot and then use it for buildings. These buildings become a carbon sink.

The issue is balance. If man cuts and burns trees for fuel we upset that balance. If we use the wood for construction AND replace those trees we have an overall positive effect. Rotting trees also add as much CO2 as burning them does. So dead trees that are left to rot are also a problem.

Destroying forests reduces the earth's ability to absorb airborne carbon (CO2). Trees as well as water, ice etc absorb CO2 that is in the air. The fewer forests there are, the fewer green leaves there are to absorb CO2. This would lead to more CO2 in the air from man-made and natural sources. More and more is released all the time and less is reabsorbed into "contained" sources such as trees and water.

If we stop deforestation by 50%, it will stop 500 billion tons of CO2 going to the atmosphere. And since carbon dioxide is a greenhouse gas, it traps heat inside the atmosphere thus affecting the climate.

For simplicity:

  1. When trees are burned or destroyed (for wood chips, paper etc) the CO2 they had stored escapes back into the atmosphere as greenhouse gas.
  2. This also means there are fewer green plants to capture carbon.
  3. Trees that are cut down and used for building or furniture retain carbon in the used timber but much of the tree is discarded and destroyed.
A:The destruction on forests impacts the global warming effect, as the trees and other vegetation in forests, absorb CO2 to use during photosynthesis. If the trees are being cut down, then less CO2 is being absorbed, essentially worsening the effect of global warming. A:Agreed above

But most people seem to forget the machinery it all produces CO2 as well as just cutting down the trees near enough everything involved in deforestation produces CO2 the humans do the machinery the trees everything.
Deforestation can influence Global warming because forests contain and store large amounts of CO2. When the forest is cleared large amounts of CO2 can be released into the atmosphere which traps heat resulting in global warming. And when the forest is cleared the trees are no longer available to remove carbon from the atmosphere.

Deforestation also results in less evapotranspiration resulting in less clouds and rainfall which also influence climate.

Is wood a renewable or a non-renewable resource?

Renewable is the key word here. Resources like gold, silver, oil, coal are not renewable, at least on a time scale we could recognize. When you use up a non-renewable resource, it's gone.

So some forests are renewable, that is, trees can be replanted and grown to maturity in place of those that are cut down.

Others are not renewable, like rain forests that have taken thousands of years to grow.

If you cut one tree down, you can plant one in its place. In forestry, this is called rotation. Many forest lands in, for example, the south of the USA, are on a 35 year rotation. The timber will be selectively harvested up to 35 years of age, then cut and replanted. This timber is a renewable resource, also called plantation forests, which are planted and then cut down to make paper. It is sometimes called a sustainable resource, so long as we keep planting and growing trees at the same rate or better as we cut them down.

Why is the Amazon Rainforest so important?

Many scientists believe the Amazon rainforest plays a crucial role in moderating global temperatures. That’s the primary reason to be concerned about deforestation efforts, but here’s a more detailed breakdown of the Amazon’s importance:

1. It removes carbon dioxide from the atmosphere.

Each year, the Amazon rainforest absorbs about a quarter of the carbon dioxide generated by the burning of fossil fuels, so it’s one of the most effective tools we have in the fight against the potentially disastrous effects of climate change.

Recent research indicates that the Amazon is becoming less effective as a carbon sink, but in 2014, a seven-year NASA study confirmed the rainforest still absorbs much more carbon than it puts out.

If the rainforest is destroyed or significantly depleted, we’ll lose this protection, and we’ll need to find more innovative ways to reduce man-made carbon output.

2. It stabilizes South American rainfall cycles.

Plants play a crucial role in the water cycle by turning water to vapor via transpiration, and the Amazon rainforest is a major factor in South America’s rainfall cycle.

There are an estimated 390 billion trees in the Amazon. If that number decreases dramatically, rainfall cycles across South America will change dramatically in unexpected ways—and that’s obviously bad news.

3. It could help us develop new medicines.

A significant percentage of our medicines use plant-derived ingredients, but scientists have only identified a fraction of the world’s likely total number of plant species.

By cataloging and studying plants from the Amazon, scientists could find cures and more effective treatments for some diseases.

“From an amoeba to an elephant, every living thing is a factory of substances, and plants aren't different,” botanist Mateus Paciencia told The Guardian. “A plant or tree is a small medicine factory. All we need to do is try and find the application for these substances.”

4. It’s the most biodiverse ecosystem on the planet.

Biodiversity refers to the number of different organisms in an ecosystem. Diverse ecosystems improve the global economy, provide resources for humans, and aid in the fight against climate change.

“Biodiversity is life on Earth, and every extinction chips away at it, undermining the stability of the planet,” Olivier Langrand, executive director of the Critical Ecosystem Partnership Fund, told Conservation International.

The ecosystems of the Amazon contain about 10 to 15 percent of the total biodiversity on land. More than 440 new species were discovered in the Amazon rainforest between 2010 and 2013, many of them critically endangered. As deforestation increases, species are lost forever—and scientists lose the opportunity to study some of the planet’s most unusual plants and animals.

Saving the Amazon also makes financial sense. By one estimate, by reducing the deforestation and degradation of the Amazon by 50 percent, the global economy would benefit to the tune of about $3.7 trillion.

Deforestation dropped by 75 percent from 2005 to 2014, but it’s currently on the rise, and the recent fires in Brazil threaten the preservation efforts. Saving the rainforest may require a global effort, but because the area offers enormous benefits to the entire planet, it’s certainly an important undertaking.

What is the importance of trees?

Trees help us breathe and provide a home for quite a few diverse kinds of animals and insects. They are the largest and longest living organisms on earth. To grow tall the tree has become a miracle of engineering and a complex chemical factory. It is able to take water and salts out of the earth and lift them up to the leaves, sometimes over 400 ft above. By means of photosynthesis the leaves combine the water and salts with carbon dioxide from the air to produce the nutrients which feed the tree. In this process, as well as wood, trees create many chemicals, seeds and fruit of great utility to man. Also, trees provide refreshing shade.

Apart from the above, trees are effectively the lungs of the environment. They take much of carbon dioxide from the atmosphere and release oxygen via photosynthesis. They also store carbon in their roots, trunk, branches and leaves. Carbon makes up 50% of the weight of the wood in a tree. Therefore, the greenhouse gas load is reduced and effects of global warming are also brought down. Further dead trees that get buried in soil eventually provide fossil fuels like coal, gasoline products, etc. Among all, trees have an indisputable role in bringing rain to earth. Moreover, they provide a cover over the top surface of earth preventing excessive heating up by solar rays.

Trees provide the human species with a constant supply of oxygen. This oxygen, which humans in turn utilize for survival, is produced through trees as they intake various amounts of carbon dioxide, which humans exhale.

A small seed becomes a big Tree, gives shed in summer and in winter all of the leaves of the Tree falls down to indirectly provide us more sunlight and the atmosphere becomes more warm.
Flower on threes give joyfulness to us. Fruits satisfy our hunger.

They (Trees) always take away polluted air (Carbon Dioxide) from the environment and in return they give fresh, purified oxygen.

Tree provide home to the Birds, Animals and Human Beings also.

Some tree have medicinal values also, their every part starting from the roots to the top are full of medicinal values, Neem (Botanical Name: Azadirachta Indica) is a very famous tree and best example of this.

Trees help in controlling temperature of the environment. You have noticed that the place where there are trees, are much more cooler and hygienic for living. That's why people prefer to spend their life in regions which are away from concrete jungle of cities Like New York, New Delhi, Tokyo, Mumbai, London, Cairo and all other big cities.

Deforestation is normal these days, this is creating a lot of problems. Some of the hazards from deforestation are as follow:

1) Soil Erosion: The trees help in keeping the soil intact with their roots but when there is lot of cutting of trees, the soil is washed away with water during the rains. And during floods the it creates havoc. Due to soil erosion the water level also falls down.
2) Pollution: Trees help in controlling the pollution in the air and if their are no trees, we have to face more air pollution.
3) Lack of Pure Oxygen
4) Environmental Imbalance
5) Imbalance in the Food Chain of the Ecosystem.
6) Global Warming is becoming a major problem these days due to this. Due to this Glaciers are melting and the Sea Level is rising day by day. This is indirectly creating lot of environmental problems.

What is a threatened habitat?

A threatened habitat is a particular animal, species, or group of species, which is being plundered by the means of hunting or killing.

Certain habitats are also plundered by natural disasters such as earthquakes.

For example, an earthquake in grassland, or any other ecosystem, will damage the wildlife of the area.

In the case of hunting, various species all around the world are killed to get their skin, hides, etc.

A habitat can also be threatened by deforestation, erosion, and pollution.

Unfortunately the work "plundered" has heavy emotional connotations. Threatening a Habitat ( I presume that you mean community) as it is impossible to separate inhabitants from environment, Is to subject the habitat or community to change, either biological or physical. When you pump the waste water from your washing machine out of the house you are threatening some habitat, a grassy area, stream, marsh , lake, river or ultimately the ocean. Putting a driveway from the road into your cabin threatens the community and habitat as you will likely alter the drainage patterns in the immediate area. (microhabitat being altered and threatened. Does dumping your unwanted coffee overboard alter the local aquatic habitat? When you finish fishing , do you save the lives of the bait minnows and turn them loose or take them home? Many waters prohibit the dumping of bait minnows as they may threaten the resident game fish.
