Today's world is getting less conscious of increasing pain and suffering caused by animals. As a result, animals became socially uneasy. Human beings treat animals as if they are material products, and continue. Because animals have their own lives, this is considered immoral. They believe that emotions can feel pain, love, happiness, and everything humans have. Regarding human rights, it is always uncertain. The Universal Declaration of Human Rights in 1948 was adopted by the UN General Assembly.
The International Animal Rights Day to be held on 10th December shows annual plight of animals every year. Supporters all over the world hold candlelight meetings and other events to arouse attention to billions of animals cruelly abused worldwide. Supporters are continually appealing the recognition of the right of all beings to life, freedom, and love. Last year, many other social movements continued similar progress by destroying working capacity, protecting and empowering indigenous peoples, coping with sexual harassment and attacks, promoting children's protection and rights. All these efforts solved rude, oppression, injustice and atrocities.
Overpopulation is one of the main problems faced by animal rights. Overpopulation may be cited as a major threat to domestic agriculture and wildlife. Over the past several centuries, the population has doubled. Due to the competition of resources and reliance on human animals, the increase in population is a big challenge for the survival of animals. As the world's population increases, abuse, elimination and killing of animals are expanding. The population now amounts to nearly 7 billion people, posing a big threat to the rights of animals. Because the more people there are, the more they are kicked out, killed, or even abused. Because of the mass consumption of animal products, the influence of human overpopulation on the rights of animals is more severe in the first world. This is in contrast to the third world where population growth rate is high, although its effect on animals is small (Roger, 2010, p. 526).
