Pls nd ! ! over time, the mushrooms that grow in a certain forest have been overharvested by humans. as a result, the number of mushrooms in the area has decreased dramatically. how will this most likely affect the environment? a) fewer forest trees will become infected with harmful dutch elm disease. b) carbon dioxide levels will decrease since mushrooms release it when they make food. c) the amount of oxygen released into the air will decline and the forest plant life will eventually die off. d) dead plant and animal waste will build up on the forest floor, attracting pesky insects and scavengers.

People are worried about too much carbon dioxide in the atmosphere because too much if it causes global warming.  Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold.  Too much carbon in the air results in global warming and many other situations. Over the years humans have increased carbon in the air by 40%. Carbon Dioxide is polluted into the air by factories, cars, deforestation, and many other things. Global Warming causes sea-levels to rise, extreme weather patterns, heat waves, and more. This presents a cause on humans because if not fixed soon, we will deal with a mass extinction.
