Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Answer:
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. ... Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect
The Great Barrier Reef is special because it is by far the largest reef in the world. It is consisted of around 2,900 individual reefs. The size of this reef is approximately as the size of Germany. There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.
The correct answer is - Greenhouse effect.
The Greenhouse effect is a process in which certain type of gasses in the lower atmosphere manage to trap the heat that is radiated from the surface of the planet.
The gases that are considered to be greenhouse gases are able to perform such a thing, despite being relatively low in amount compared to other gases, because they have much more complex molecular structure.
The molecular structure of this gases enables them to trap the heat, or rather to not allow to leave the atmosphere and return it back toward the surface, thus having huge effect on the climate.
Greenhouse gases are the carbon dioxide, methane, water vapor, nitrous oxide.
Climate and resource availability.
