As the human population grows, people build more roads and drive more cars. This can make it difficult for animals to move around safely.
When a road cuts through a forest or a field, it splits the animals’ home into smaller pieces. Animals might need to cross the road to find food, water, mates, or a safe place to sleep. With more cars on the road, there’s a higher chance that an animal will try to cross at the same time a car is driving by. This can lead to more accidents, which are bad for both the animals and the people in the cars.
