Answer:
Humans cause change in the environment as there is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to increase. That greenhouse gases "trap" infrared heat is well established through laboratory experiments going back to 1856 when Eunice Foote first measured the effect.The well-documented trend of increasing of CO2 in the atmosphere is caused by the burning of fossil fuels and massive land cover changes. The "smoking gun" that shows clearly that human activities are responsible for recent increases in carbon dioxide in the atmosphere is provided by carbon isotopes (carbon atoms of different atomic weight). These isotopes allow scientists to "fingerprint" the source of the carbon dioxide molecules, which reveal that the increased CO2 in the atmosphere is caused by fossil fuel burning also.
B. Manifest destiny would be the answer
Since you have not given me the choices, I'll only discuss what is wetland and what are it's danger when it will be destroy.
Wetlands are the places that contains body of water like ponds, seashore, or river.
Since this is a wetland, expected that there will be a lot of species living in their and having their habitat like fishes, frogs, algaes and more.
Now, when this place become destructed, all these species will lost their habitat and soon die.
We all know that in our world, we depend on each other. so what will we do if our food will no longer exist?
