animals are becoming endangered because of habitat destructoin

Animals that are endangered have a much bigger risk of going extinct now than four years earier. Why? Since we have been making new roads and tearing down woods to do this, we've been the cause of the destruction of their habitats. So, that new road is danger to the animals that lived in that area because we litter and run over these poor animals that lost thier homes to us. Also, the gas from your car is also pollute the air which makes the o-zone layer have a bigger hole and by then the animals in the colder regions are dying because the waste that is frozen is melting and littering the ocean.(which some people already litter the ocean) So please help by walking or biking.
