Urbanization is just one of the many effects of overpopulation here on Earth, along with the rapid dwindling of the natural environment as a whole. The general consensus across the scientific community is that a number of factors have contributed to global overpopulation. More than 7.7 billion people live on Earth as of 2020, largely […]
A full 20 years into the 21st century, the threat of overpopulation continues to make headlines across the globe. A recent United Nations study determined that the global population, currently sitting at 7.7 billion, will increase to about 9.7 billion by 2050. That equals a 28% population increase, or approximately 82 million additional people every […]
The idea behind controlling waterways through dams isn’t new. The oldest dam in the world, the Kallanai Dam, began operation on the Kaveri River in Tamil Nadu, India in the 2nd century, and it’s still in use today.
The era of climate change is upon us, and if we stand idle, its far-reaching negative impact will only increase. Increased emissions of greenhouse gases like carbon dioxide, methane, and nitrous oxide play a significant role in the onset of climate change. Gases like these trap heat in the atmosphere, not allowing temperatures to fall. […]
One fact about our time is becoming increasingly well-known. No matter how far you travel, no matter in which direction you point, there is nowhere on Earth that remains free from the traces of human activity. The chemical and biological signatures of our species are everywhere. Transported around the globe by fierce atmospheric winds, relentless […]
Whilst air pollution is a problem all around the world, it can be particularly troublesome in developing countries. According to the World Health Organisation (WHO), 98% of inhabitants of big cities in low-income countries live in a high level of air pollution, leaving them with a number of health problems due to the poor quality […]
There is no way of protecting the climate without drastically mitigating fossil fuel combustion. Nearly half of CO2 pollution comes from power plants burning fossil fuels. But there’s a way to turn things around. Renewable energy cuts down carbon pollution and has a much lower impact on the environment.
Gareth Dorrian, University of Birmingham and Ian Whittaker, Nottingham Trent University In a rare instance of environmental success, the United Nations has just announced it believes the damage to the Earth’s protective ozone layer will be fully restored by the year 2050. This stands in stark contrast to the increasing alarm over the climate emergency, […]
When you think of the Grand Canyon or the Great Smoky Mountains, beautiful scenery immediately comes to mind. You might begin to imagine the incredible views, towering cliffs, lush landscapes and color schemes that far exceed anything you’ve ever seen in a painting.
Today, climate change is a very real and looming threat. However, when the subject of climate change and possible solutions is discussed, the phrase “we need bigger changes” is often bandied about. Individuals tend to shift the responsibility of fixing human-caused damage to the environment to larger systems – but with little concrete action being […]
