IMPORTANCE OF FORESTS

Forests and biodiversity is key to all life forms. The richer the diversity of life, the greater the

opportunity for medical discoveries, economic development and adaptive responses to such new

challenges as climate change.

Below are some more importance of forests:

WATERSHED Forests serve as a watershed. This is because almost all water ultimately comes from rivers and

lakes and from forest-derived water tables. Some rivers running through forests are also kept

cool and from drying out.

HABITAT AND ECOSYSTEMS Forests serve as a home (habitat) to millions of animals. Think of the many types of reptiles

(snakes and lizards) wild animals, butterflies and insects, birds and tree-top animals as well as all

those that live in the forest streams and rivers.

Animals form part of the food chain in the forests. All these different animals and plants are

called biodiversity, and the interaction with one another and with their physical environment is

what we call ecosystem. Healthy ecosystems can better withstand and recover from a variety of

disasters such as floods and wildfires.

ECONOMIC BENEFITS Forests are of immense economic importance to us. For example, plantation forests provide

humans with timber and wood, which is exported and used in all parts of the world. They also

provide tourism income to inhabitants (people living in or close to forests) when people visit to

see the best of nature.

CLIMATE CONTROL

Climate control and atmosphere purification is key for human existence. Trees and soils help

regulate atmospheric temperatures through a process called evapotranspiration. This helps to

stabilize the climate. Additionally, they enrich the atmosphere by absorbing bad gases (example

CO2 and other greenhouse gases) and producing oxygen. Trees also helps to remove air

pollutants.

CAUSES OF FOREST DESTRUCTION Immediate Causes: The immediate causes of rainforest destruction are clear. The main causes of total clearance are agriculture and in drier areas, fuelwood collection. The main cause of forest degradation is logging. Mining, industrial development and large dams also have a serious impact. Tourism is becoming a larger threat to the forests. 1.1 Logging

Commercial logging companies cut down mature trees that have been selected for their timber. The timber trade defends itself by saying that this method of 'selective' logging ensures that the forest regrows naturally and in time, is once again ready for their 'safe' logging practices (WWF).

1.2 Agriculture - Shifted Cultivators 'Shifted cultivators' is the term used for people who have moved into rainforest areas and established small-scale farming operations. These are the landless peasants who have followed roads into already damaged rainforest areas. The additional damage they are causing is extensive. Shifted cultivators are currently being blamed for 60% of tropical forest loss

1.3 Agriculture - Cash Crops and Cattle Ranching Undisturbed and logged rainforest areas are being totally cleared to provide land for food crops, tree plantations or for grazing cattle (Colchester & Lohmann). Much of this produce is exported to rich industrialised countries and in many cases, crops are grown for export while the local populace goes hungry.

1.4 Fuelwood The United Nation's Food and Agriculture Organisation estimates that '1.5 billion of the 2 billion people worldwide who rely on fuelwood for cooking and heating are overcutting forests'. This problem is worst in drier regions of the tropics. Solutions will probably involve a return to local peoples' control of the forests they depend on.

1.5 Large Dams In India and South America, hundreds of thousands of hectares of forests have been destroyed by the building of hydro-electric dams. It was the dominant view that new dams had to be built or otherwise these countries would suffer an energy crisis. However, a recent study by the World Bank in Brazil has shown that 'sufficient generating capacity already exists to satisfy the expected rise in demand for power over the medium term, provided that the energy is used more efficiently' (WRM).

1.6 Mining and Industry Mining and industrial development lead to direct forest loss due to the clearing of land to establish projects. Indigenous people are displaced. Roads are constructed through previously inaccessible land, opening up the rainforest. Severe water, air and land pollution occurs from mining and industry.

1.7 Colonisation Schemes Governments and international aid agencies for a time believed that by encouraging colonisation and trans-migration schemes into rainforest areas, they could alleviate some of the poverty felt by the people of the financially poorer countries. It has since become increasingly obvious that such schemes have failed, hurting the indigenous people and the environment

1.8 Tourism The creation of national parks has undoubtedly helped to protect rainforests. Yet, as national parks are open to the public, tourism is damaging some of these areas.

Underlying Causes:

Poverty and overpopulation are believed to be the main causes of forest loss, according to the international agencies such as the FAO and intergovernmental bodies. They believe they can solve the problem by encouraging development and

trying to reduce population growth. However, the World Rainforest Movement and many other non-governmental organizations hold unrestrained development and

the excessive consumption habits of rich industrialized countries directly responsible for most forest loss.

2.1 Development and Overconsumption: the Basic Causes The roots of the problem of deforestation and waste of resources are located in the industrialized countries, where most of our resources, such as tropical timber end

up. The rich nations with one quarter of the world's population consume four fifth of the world's resources.

2.2 Colonialism

Tropical rainforests are found mainly in the Third World countries, Australia and

Hawaii being the only exceptions. All of these countries have indigenous populations who had their own system of land management and/or ownership in

place for thousands of years before the intervention of colonists from rich industrialized nations. The colonial powers (Britain, France, Spain and Portugal), whilst exploiting the resources of many of these countries, attempted to destroy

indigenous peoples' rights to remain on their land. Colonialism turned previously self-sufficient economies into zones of agriculture export production (Colchester and

Lohmann). This process continues today and the situation is worsening.

2.3 Exploitation by Industrialized Countries

Wealthy countries have been consuming so much of their own resources that they are no longer sustaining their growing populations and increasingly, they are

turning to the resources of the financially poorer countries.

2.4 The Debt Burden

The governments of the financially poorer countries feel they need to make money in order to repay their huge international debts. In the 1970's and 80's, they

borrowed vast sums of money from development agencies in industrialized countries in order to improve their own economies.

2.5 The Role of Poverty and Overpopulation

Poverty, while undeniably responsible for much of the damage to rainforests, has to a large extent been brought about by the greed of the rich industrialized nations

and the Third World elites who seek to emulate them.

Dear Susan,

It feels like such a long time since the last time I saw you. I know its only been several weeks

since I saw you. So far my summer has been great!

I spend my all my weekends at the beach. I am getting a nice tan and you can no longer say I am

paler than you. I have been playing lots of volleyball, surfing and building a nice collection of

sea shells. Just this past weekend I took second place in a sandcastle building contest!

On the weekdays I work. I drive an ice cream truck around and sell ice cream to the kids. It is so

cool. It is a combination of the two things I love most, ice cream and kids. The pay isnt too great

but I love the job so much.

I hope the summers been going well for you too. Theres only a month and a half left in summer

vacation and after that its back to school. Would you like to meet up some time to before school

starts?

Your friend,

Agnes
