Deforestation and Habitat Loss
This category deals with the causes and effects of changes in natural habitat. Examples would include questions about cutting down forests, plowing grasslands for agriculture, coral reef die-offs, and the natural process of succession.
What are the positive effects of man on nature?
The positive impact of humans on the nature (i) Humans are responsible for the introduction of new species of plants from one part of the world to another; for example, rubber from the Amazon Basin of Brazil was brought to Malaysia, which is now the world's largest producer of rubber. (ii) By selective breeding, he has improved the yields of crops. (iii) By domesticating animals he has protected them from their predators. (iv) New breeds of cattle have been developed which give much higher yields. (v) He has made...

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...
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...

What is cutting down a forest without replanting?
Answer 1: cutting down a forest without replanting some trees is really bad. in 5 years we lost 132,000 square kilometres of the Amazon and were going to lose another 85%. if your cutting down trees at least do what velvet does ,if you take 1 replant 3. Answer 2: The answer is deforestation.:) ...
Asked in Deforestation and Habitat Loss
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. ...
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...
How are forests useful to us?
Forests help us to maintaian an ecological balance. they help to purify the air,regulate the climate, prevent soil erosion and replenish ground water and they are a rich source of medicinal plants and rare fruits . ...

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)...
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...
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...

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...
Why is it bad to cut down trees and use it for paper?
It is bad because what is the use of paper when there won't be oxygen to live we can't change the paper back into trees can we. If we cut trees and make paper pollution will become more. Less rainfall and Less oxygen Thanks Gaurang ...

Destruction of the rain forest leads to?
when we cut down a tree all the carbondioxide that it sucked in gets released into the air which is definately not a good thing. Also if we continue to destroy trees we won't have enough oxygen. Some of the animals that live in the forest will also die. And you may not believe but every single animal has it's purpose (yes even mosquitoes) ...
Why should you conserve forest and wildlife?
Answer Most people are too busy with their own little lives to realize what is going on in the environment and eco system and it's important we look up information on the Internet to be aware of what we should fight for as far as clean air and keeping our forests and animal life safe and healthy. Nature is a delicate balance and everything has a use to keep that balance. Because of poor air quality in many cities in the world...
