    Battle for the Biosphere

    Battle for the Biosphere

    The value of the biosphere

    Use for survival (of humans andanimals)

    Commercial use (for money andbusiness)

    Rainforests and coral reefs are very bio-

    diverse they provide habitats and homes

    for a large number of animals.

    orests remove carbon dio!ide from the

    atmosphere and provide us "ith o!ygen

    to breathe.

    orests can help prevent flooding

    because of interception.

    orests can provide us "ith timber

    "hich "e use to ma#e furniture and for

    building.

    Rainforests can provide us "ith

    medicines and cures.

    Rainforests and coral reefs often

    attract tourists.

    How have humans effected the biosphere: The Amazon Rainforest

    $ biomeis a very large ecosystem

    The effects of climate change %ncrease in temperatures along "ith "ild "eather "ould

    cause "idespread changes to the $ma&on.

    %t "ould trigger a shift from humid rainforest to drier

    savanna ecosystems. 'his "ould affect the delicate bio-

    diversity (plants and animals living there).

    ildfires "ould also become more freuent due to the

    hotter and drier "eather.

    'hese are problems because the rainforests are a huge

    store of carbon for the atmosphere. %f the forests "ere

    lost the carbon "ould be released and global "arming

    increased

    Battle for the Biosphere

    How can the Amazon Rainforest be managed?

    Eco-tourism in the Amazon

    'his aims to develop tourism in the $ma&on "hich is good for the

    environment* "ildlife and local people.

    +eople stay in ,ungle lodges "hich has very little impact on the rainforest. 'ourists learn about the rainforest. %t also provides ,obs for local people

    "or#ing as guides* in hotels and selling souvenirs.

    t is sustainable because it is not cutting down the rainforest! instead

    it is educating tourists and providing income for local people"

    Harvesting vines from the Amazon

    'his pro,ect involves cutting do"n vines in the rainforest* not the trees.

    'he vines gro" bac# uic#ly and the trees are unaffected.

    'he vines are used to ma#e bas#ets and develop industries* giving local

    people ,obs and money.

    t is sustainable because it is not cutting down the rainforest! it isproviding people with #obs and income without having an$ lasting

    damage"

    %hat other wa$s is the biosphere protected

    RA&'AR convention: $ims to protect "etland areas

    (TE' convention: $ims to stop trade in endangered animal goods

    )ational *ar+s: $im to conserve areas of natural beauty (e.g. e" orest* U)

    (ommunit$ ,orests: $im to provide ne" areas of trees near ma,or cities.
