It could cause some insect species to destroy native plant species.
How does the tilt of the Earth’s axis affect the seasons?
by changing the amount of direct solar energy reaching the surface of Earth
by influencing the rate of chemical reactions occurring in the atmosphere
by deflecting the harmful rays of radiation emitted by the sun
