They would DIE!
You would all be dead from global warming.
First, all of the plants and trees would die. Then all the animals, including humans; would die.
The population of all of the animals that got food from the trees would drop as well as the animals that eat those animals so on and so forth.
if all the animals were gone there would be no carbon dioxide for plants and trees to take in and no oxygen would be produced.
All of them would die, they would not be able to find food from anywhere else, after the herbivores die it would start to affect the carnivors. They'd be able to eat the remains of the dead animals but when they have all been eaten then the carnivors would start to die until no animals were left. Even sea animals would die due to the heat from the sun being more higher as CO2 levels rise, all the water would evaporate and the sea animals would die of suffocation.
There would be a massive canopy.
There won't be so many disgusting animals.
We would all die cause trees give us oxygen and carbon dioxide.
there actually be little to no trees and possibly we would all die
If there were no trees, our world would be drastically different. Trees provide oxygen, shelter for animals, and help regulate the climate. Without trees, many animals would lose their homes, and our air quality would suffer. It's important to protect and preserve trees for the health of our planet and all living creatures.
All the trees would fall to the center of the Earth.
all trees would die
