The answer should be D. From the remains of dead plants and animals.
Plants provides oxygen, and plants need a comfortable climate to grow to their fullest potential. But because of the populations unsustainable practices (activities that cause pollution to the air, water and land), the climate has changed drastically. So drastic that the conditions are unsuitable for plant life. Without plants, the pace of climate change will only increase — as will desertification, soil erosion, flooding, and an increase of greenhouse gasses in the atmosphere.
The Earth is round so that we have day and night. If the Earth was not round, it would not rotate and half of the world would be dead because it would never get any sunlight, and the other half would probably die because of how hot it is. Additionally, if the Earth wasn’t round we wouldn’t have balanced gravity and the Earth would be unable to revolve properly around the sun.
Hope this helps!
