On the one hand, "Factfulness" objectively shows that the world has improved tremendously over the long run. On the other hand, increased demand for goods and services have lead to environmental problems in many parts of the world - some irreversible. While infant mortality is very low due to medical advancements and the amount of marine sanctuaries have increased over the years - does not discount the fact that heavy fuel powered trading vessels and cargo ships continue to add immense noise and air pollution to the environment as trade opens up. In Sri Lanka, the construction of mega sea-port disrupts and destroys natural coastlines. The environment is sacrificed for economic growth. The growing tourism industry continues to stress the fragile environment. Air travel continually adds noise and air pollution to the skies. Many birds have lost their lives as a result of being sucked into airplane engines. While being optimistic is good, humans cannot remain ignorant that much of today's economy only serves to degrade the natural environment further.
