I guess the stomach is held in place by a variety of Muscle cells, Epithelial cells, and connecting tissues; so the answer is: all of the above.
Drilling for fossil fuels.
This is because the main fossil fuels are not typically found in the rainforest. To also back up this claim, use the process of elimination.
The last choice, demand for rainforest products, is obviously incorrect as that would mean expansion into the rainforest to gather said products.
Shortage of food sources wouldn't be the correct answer either as food sources aren't typically found in the rainforest among popular demand and food can be shipped into the country as well.
Overcrowding in cities would also lead to expansion, where to can differ based on location but to rainforests or anywhere surrounding the area would be preferred or desirable.
Hope this helps!
When a new technology is introduced, there is geo-testing performed to see how this new extraction method effects the environment. The over all effects and efficiency are what should determine the acceptance of these solutions.
