How can tourism positively affect the conservation of forests?

well lets look into this shall we,
to be honest it can have positive and negitive effects.
it could effect the natual and social economic envirement,
but were just focusing on the positive,
not meaning to kick a curb into a stump but sounds a bit like trump,
cant just say the good and completely unprehend the bad,
the bad is what brings rainbows,
anyhow,
there are local, regional, and global,
these are the rated or sections of welll simplified there scales,
whatever thats what they are i read it once in a book so it has to be right,
now global for example that would be the gas,
or vehichle polution,
i mean here comes tourists so there will be polution simple,
conversatition benifite il admit rely on the choices we choose to make,
along with location and travel options and activities we plan on doing,
also brings up a thought,
were comes tourism comes jobs,
and here comes employments,
witch is a positive thing,
it leads to making money and them spending it on more things,
creating more what i call the multiplyer effect,
because then more job openings occur,
and so on,
here comes a negitive,
our roads and everything such as houses,
get ready is from our taxes,
boo,
but true,
so more people means more needs for building so more tax,
heres a positive,
tourism leads to the exchange of coulture and trade,
and lead to festivals and what not,
now lets finish off with a bad,
you see tourists end in rationing food,
meaning less food and water suply,
because well simple they used it all,
anyhow iv explained enough,
and i dont wish to get in trouble with another 5 thousand word answer,
for this essay,
so il put it simply,
iv explained good and bad in less than 
1,500 words,
i should know,
i counted them,
well Mister Creed catch ya on the flip side of things,
your the coolest man!
