Will give a brainlest which does not lead to expansion into the rain forests of developing nations? overcrowding in cities drilling for fossil fuels shortage of food sources demand for rainforest products

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!

Thats bot a question
