During the era of slavery in the United States, the education of African Americans, enslaved and free, was often discouraged, except for religious instruction, and eventually made illegal in many of the Southern states. It was believed that literacy was a threat to the institution of slavery. First, literacy facilitated knowledge about the successful slave revolution in Haiti of 1791–1804, the end of slavery in the British Empire in 1833, and the writings of abolitionists.

<h3>
What is sustainability ?</h3>
Sustainability is a social ideal that, in general, seeks for long-term human coexistence on Earth in safety. Since there is no universally accepted definition of sustainability, there are many different ones in the literature and over time. Meeting our needs today without sacrificing the potential of future generations to do the same is what is meant by sustainability. Along with natural resources, we also require economic and social resources. Sustainability goes beyond environmental concerns.

What makes a lifestyle sustainable?</h3>
Living sustainably is a practical attitude that attempts to lessen societal and individual environmental impact by implementing actions to combat climate change and other serious environmental issues. Living sustainably is, to put it another way, a way of lessening one's "carbon footprint".
