Earthworms make burrows in the soil and make it porous which helps in respiration and penetration of the developing plant roots and hence, are called farmer's friends. They have the capability to maintain the fertility of the soil and hence, play a crucial role in sustainability.

There are not enough homes for all the animals that are born every year. Adopting from a shelter helps weaken the pet overpopulation cycle. Each year 8 to 12 million dogs, cats, puppies and kittens are euthanized because there are simply not enough homes for them.
