Answer:
The enviornment is important because its where animals interact with nature, materials, and how they live life. Messing with the environment can kill a whole species or even a whole forest. The environment is where animals make their habitat and improve their own homes. Without environments we would not be able to live because the food we need would end up dying or just moving to find another location to live. Without prey or predators, the environment in incomplete and there's a high chance we will overpopulate or just die.
