25 Alarming Ecological Changes Within This Century

Human beings have been living on Earth for tens of thousands of years and for the better part of it, we did so without causing any damage to Mother Nature. It’s true that most ancient civilizations, such as the Greeks, the Egyptians, the Mayans, the Mesopotamians, the Persians, the Indians, and the Native Americans among others, lived for a very long time in perfect harmony with the natural environment. However, the large increase in the global population and the Industrial Revolution (and the subsequent mass migration of multiple populations to urban areas) drastically changed things for the worse. In particular, the environmental pollution associated with these events has had some adverse ecological changes on the planet for almost two centuries now.

The extremely harmful effects of human activity on our planet’s biophysical environment are more alarming than ever before and most scientists keep warning government leaders about the catastrophic effects this could have for us. So, if we want to continue surviving as a species we must reconsider several things and learn how to live in harmony with each other as well as nature, and respect the environment. The following 25 Alarming Ecological Changes in this Century are not just risks anymore, but horrifying and threatening realities for the present and near future.

The human population is growing as never before. We are now adding one billion people to the planet every twelve years. That’s about 220,000 per day. Truth be told, human overpopulation appears to be among the most pressing environmental issues, silently aggravating the forces behind climate change, environmental pollution, and habitat loss, while continued building and burial of humans all over the world only makes things worse.

Over three-quarters of our planet is covered by water. Ocean biodiversity is unmatched and they contain over 80 percent of all life on Earth, mostly unexplored. Millions of people worldwide depend on the oceans for their livelihood but increasingly this has become endangered because of ignorance and a lack of global management, which often leads to overfishing.


Nuclear Issues

Despite popular belief, the greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal, oil, and gas. However, there is a “catastrophic risk” potential if containment fails, which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the environment.


Natural Disasters

The cataclysmic natural disasters that have taken place in the past fifteen years, such as gigantic tsunamis in Asia and their terrible impact on all aspects of the environment, are becoming an increasingly alarming problem that the scientific community is watching closely.

Even though most technology technicians worship nanotechnology and focus almost exclusively on its advantages, there are equally as many experts who warn about the future effects of nanopollution and nanotoxicology.
