Yes, I did realise that i.e. rainforests, that's why I specified plantation forests in my answer.matt_f64 said:no most minerals are generally seen as non-newnewable as they take millions of years to replenish....
also u mite interested to no even some trees are NOT renewable.. there are a select few that take several hundred years to replenish so they are classified as NON-renewable.
lol i wasnt actually referring to u, i was more talking about sweet lemon cos they said "minerals" so i was jst saying its classed as non-renewable then i remembered how our teacher told us about some trees being non-renewable.Shuter said:Yes, I did realise that i.e. rainforests, that's why I specified plantation forests in my answer.
Ahahahahaha that's hilarious, and correct, I like your style.Acid said:I couldn't think of an example when I was sitting there so I just put "e.g. fruit"
as for this guy.. i really dont no wat hes on about.. im assuming hes saying we burn up ethanol in cars and that natural gas is a NON-renewable resource? cos the question did say RENEWABLe. oh wellsub said:i used the chem example of ethanol for cars...hahaha, i went mind blank and that's all that came up
yeah, we had to do renewable sources for fossil fuels (in this case octane for petrol) in chem, and one was ethanol (as car fuel). its renewable cos u can ferment it from sugar cane etc... hence a renewable source...it was all that came to me in the exam.matt_f64 said:as for this guy.. i really dont no wat hes on about.. im assuming hes saying we burn up ethanol in cars and that natural gas is a NON-renewable resource? cos the question did say RENEWABLe. oh well
Yeh i said exactly that too - thats straight from leading edge textbook that overexploitation one and so i used that eg saying fish are renewable, but if they are seen as infinately renewable, they become overexploited then they may no longer be renewableRorix said:i said something like 'renewable resources are resources which, if carefully managed, will be able to provide for the needs of present and future generations. Renewnable resources may become non-renewable if overexploited e.g. fishing stocks'
