Deforestation & conservation efforts Presentation Transcript

    • About 11000 ago, before Man learnt to cultivate land for growing his own food, a large part of the Earth was covered with forests. Today, six out of ten forests have been cleared, so that they now cover little more than one-fifth of the land on Earth. Destruction of forested land is called deforestation.
    • Deforestation occurs for
    • many reasons: trees or derived
    • charcoal are used
    • as, or sold, for fuel or as
    • a commodity, while cleared
    • land is used as pasture for
    • livestock, plantations of commodities, and settlements.
  • 4.
    • The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland. Currently, 12 million hectares of forests are cleared anually.
    • Biosequestration is the capture and storage of the atmospheric greenhouse gas carbon dioxide by biological processes.
  • 5.
    • Because of this, merely replanting trees may not help in solving the problem caused by deforestation, for by the time the trees mature, the soil will be totally devoid of essential nutrients. Ultimately, cultivation in this land will also become impossible, resulting in the land becoming useless.
  • 6.
    • Erosion of Soil : When
    • forest areas are cleared, the
    • soil is exposed to the sun,
    • making it very dry and
    • eventually, infertile, due to
    • volatile nutrients being lost.
    • In addition, when there is
    • erosion, rainfall washes away
    • the rest of the nutrients, which
    • flow with the rainwater into
    • waterways.
  • 7.
    • Disruption of the Water Cycle : Trees
    • contribute in a large way
    • in maintaining the water
    • cycle. They take in water
    • via their roots, which is
    • then released into the
    • atmosphere. A large part
    • of the water that circulates
    • in the ecosystem of
    • rainforests, for instance,
    • remains inside the plants.
    • When these trees are cut
    • down it results in the climate
    • getting drier in that area.
  • 8.
    • Loss of Biodiversity : The unique biodiversity of various geographical areas is being lost on a scale that is quite unprecedented. Even though tropical rainforests make up just 6 percent of the surface area of the Earth, about 85 percent of the entire species of the world exist here. Due to massive deforestation, about 50 to 100 species of animals are being lost each day. This puts the extinction of animals and plants on a massive scale.
  • 9.
    • Flooding and Drought :
    • One of the vital functions of
    • forests is to absorb and
    • store great amounts of
    • water quickly when there
    • are heavy rains. When
    • forests are cut down, this regulation
    • of the flow of water is disrupted, which leads to
    • alternating periods of
    • flood and then
    • drought in the
    • affected area.
  • 10.
    • Climate Change : It is well known that global warming is being
    • caused largely due to emissions of greenhouse gases into the
    • atmosphere. However, what is not quite known is that
    • deforestation has a direct association with carbon dioxide
    • emissions into the atmosphere. Trees act as a major storage
    • depot for carbon, since they absorb
    • carbon dioxide from the atmosphere
    • to photosynthesis to produce
    • glucose which makes up trees. When
    • deforestation occurs, many of the
    • trees are burnt or are left to rot,
    • which results in releasing the carbon
    • that is stored in them as carbon dioxide. This in turn leads to
    • Greater concentrations of carbon dioxide in the atmosphere.

  • 12.
    • Recycling : we should recycle all the thing
    • that are made of tree ex. Paper, bags,
    • furniture, etc. because it lead to the
    • less cutting of tree and also
    • the products of trees will be
    • used wisely.
    • Wood factories: we should stop or lessen the production in those factories that cut down trees to make their products ex. paper, furniture, etc.
    • •  People's basic needs: we all know that the colossal cause of deforestation is people's needs from the forests. Even though we depend on the forests, we should learn to lessen our dependency on the forests and their environment. So we need to use a little of them as possible and wisely.
  • 13.
    • Paper: paper is one of the
    • most important things in the
    • world without it we can't do
    • almost anything. We can't
    • study, write, learn and a lot of
    • stuff which is impossible to do
    • without paper, but many of the forests are destroyed just to make paper out of them. So lessen your dependency on the paper and try to use as less as possible and recycle them.
    • Reforestation: after cutting down a tree we should plant two because this way there will be a balance of
    • ecosystem and the rate of deforestation will diminish.
  • 14.
    • Sungei Buloh Wetland Reserve’s “Reforestation and Reachout” started in August 2004, with the generous sponsorship of Toyota Motor Corporation and the participation of five schools. The programme aimed to involve students in reforesting the area around the outdoor classroom and to create educational materials based on their experience. It was hard work in the beginning sourcing committed and willing activists. However, we did still manage to secure five schools willing to participate and commit at least six to eight months of their time for this project.
  • 15.
    • The area around the Outdoor Classroom at SBWR showcased the diverse habitats of the Wetland Reserve, namely the mangrove, back mangrove, secondary forest and freshwater pond.
    • Each of these habitats had its own uniqueness, which supported diversities
    • of flora and fauna. A
    • small spice garden
    • was also planted to
    • help the visitor link his
    • new experiences of the
    • Reserve’s plants to something
    • he is likely to be familiar with.
  • 16.
    • From August 2004 to November 2004, the activists underwent a series of workshops conducted by SBWR staff and volunteers. These workshops included an orientation programme to familiarize them with their respective sites and to explain the need for reforestation. Through sessions on plant drawing, public speaking and presentations, resource searching and creating educational materials, they broadened their “outreach” scope. Given a list of plants to start with, the activists were encouraged to go a step further to find out more about the ecology of the area, and the benefits of reforestation.
  • 17.
    • The session on public speaking enabled and equipped the activists with necessary speaking and presentation skills.
    • They embraced the message
    • of nature conservation –
    • what this wetland reserve has,
    • the importance of trees –
    • and brought forth a call to their
    • peers to join them for a day of
    • reforestation, at the Outdoor
    • Classroom.
  • 18.
    • Sungei Buloh had a good range of participating schools, both local and international, with an age range of 10 to 18 year olds. The student activists were made up of Singaporeans and a diverse group of other nationalities, which include UK, Canada, Sweden, New Zealand, Korea, Taiwan, Indonesia, Malaysia, Sri Lanka and Vietnam.
  • 19.
    • The role of the activists was to learn first hand about reforestation and rally their friends to join them in planting a new generation of trees and shrubs at Sungei Buloh Wetland Reserve. Each school had eight activists to represent their school in this project.
  • 20. “ For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold or silver.” -Martin Luther 1483~1546
  • 21. Wilderness and forests around the globe are being depleted rapidly, and are becoming confined primarily to islands, parks and reserves. The health of our planet’s forests will depend on how well we manage and protect the few remaining areas we have left. Forests are not only sanctuaries of wildlife, but of the human spirit. Every tree adds vibrancy, colour, magnitude, and they are vessels of health and vigour. Please, for the sake of man’s future, do contribute.
