There are a lot of human activities that gives negative effects on the earth's ecosystem but I will mention only four: Burning of things such as garbages or plants and trees, dumping of garbages anywhere, chemical substance that are being made and produced, cutting down of trees for replacement of buildings and homes. The human activities increase the occurrence of species extinction by doing this, it eliminates and destroy the homes of the species that are supposed to be living on their natural habitat. But instead of them, living peacefully, by doing these activities, their home will be destroyed that can kill them-- which can lead to extinction.

C) The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.
Explanation:
The increase in greenhouse gas emission cannot be likened to placing an extra log on the fire to produce more heat.
In essence, the earth is not receiving more heat than usual from the sun. It is not getting more heated.
- Greenhouse gases prevents heat from being lost from the earth surface as long wave radiation.
- This in turn will warm and heat the earth surface.
- The more the greenhouse gases, the more heat that is trapped within the earth.
- The greenhouse gases is the cover that prevents heat from being lost.
- Global warming is what results.
- An increase in heating might not cause warming of the house if the house is open.
- So also, if the earth receives more energy from the sun, the temperature might not increase if no greenhouse cover is available.
Other analogies shows heating(global warming) and cover(greenhouse gases) except of C.
