    I'm going to stick with NT on this.
    Conservation is the management of the Earth's natural resources, so that we can maximise our use of them.
    Reasions for this: ethical - think of the poor animals and plants
    economic - species in the rainforests could have medical uses, we can use wood, oils, rubber etc.
    cultural and aesthetic - the explanation for this one always makes me laugh in the CGP book. Please can we have some real biology?

    Conservation is usually achieved by managing succession.

    In the spec, all it says is: - Conservation of habitats frequently involves management of succession.

    Candidates should be able to:
    Use their knowledge and understanding to present scientific arguments and ideas relating to the conservation of species and habitats

    Evaluate evidence and data concerning issues relating to conservation

    Explain how conservation relies on science to inform decision-making

    Quick question guys, how do you work out the likelihood of the next child of 1 and 2 being a female with a disease, if the chance of the next child having a disease is 50%?

    I know the answer is 25%, but how do you get there?

    Is it it just: chance of child having disease: 50%. Chance of child being female: 50% so 50/2 = 25%?

    yeh ... just divide it by two as there is a 50/50 chance of it being male or female. you looking at the first question on the spec paper?

    hey, does anybody reckon they could ask a 5 mark question on conservation? For example, the importance of it? if so what will you include?

    Also, do you think they can ask a five marker on climate change, carbon dioxide and methane?

    Thanks

    BRING IT ON

    The majority of the time, it's the calculation questions, where you read of graphs, and have to do rates, and whatnot that I just cannot get right. (weinberg etc. is fine)
    And i do a level maths. fml.
