These rights consist of rights such as the right to work, to health care, and to decent housing. The third generation rights protect group rights, collective rights, cooperate rights, people rights, and cultural rights. Human rights are derived from human needs and humanity. A person doesn't need much to survive, maybe some bread, water and a little sunlight. But to live well and enjoy life you need human rights.
Human rights give people the choice to live to their potential and to live a life of dignity.
Human rights are most needed when they are threatened. If human rights are threatened then one, must act with assertive exercise and stand up for his rights. I was born with every criteria of a human being and therefore I have human rights. So I have the right to enjoy my life. That is why we need human rights and legal rights to protect them.
