"The greatness of a nation and its moral progress can be judged by the way its animals are treated." - Mahatma Gandhi

There are few nations in the world who spare a thought about the need for co-existing with animals. Human expansion often trespasses on and even destroys natural habitats leaving animals with meagre options for survival. The fact that animals are also living beings with the desire to live is often forgotten in our greed. However, with animal activists striving to spread awareness about this, several nations have woken up to the need of protecting animals. Bridges and underpasses for animals are built on roads to avoid accidents and deaths by vehicles and laws are put in place safeguarding animals.

Here are some images of bridges built for animals in different countries to help them cross roads safely:
