Just because animals cannot speak for themselves, human beings do not seem to care for them as much but you can change it as there are many ways through which you can make an impact and bring happiness into the lives of pets.
Help a Welfare Organization
There are many animal welfare organizations like PawSafe Animal Rescue that work day and night to provide better lives to animals everywhere so if you want the same then you can always be a part of these organizations by donating some amount of money or the items that they need. If you think that you have nothing to give then you are mistaken because you have your time, you can always volunteer at animal shelters and welfare organizations and help them achieve their different goals which will ultimately help pets everywhere.
Adopt a Pet
If you do like animals and wish to contribute to their happiness then you can adopt an animal and make it your pet. You might think that adopting one pet does not make a difference but it does, if each of you adopt one single pet then there would be numerous pets who would be living better lives than before but we urge you to only adopt an animal if you think that you would be able to provide it with all your love, care, attention and a safe environment because if you cannot do all of that then you would be treating the animal wrong.
Even in this day and age, some people do not treat their pets as they should so if you know anyone like that and even if you do not, you should educate yourself first about how to take care of pets and then educate others.
