Let's talk about sperm, and more precisely Western male's sperm, because it seems male fertility is facing a sharp decline in Western nations - and environmental pollution could be responsible. According to a study published this past summer, there may be something weird going on with men's sperm. The study found a sharp decline in sperm count between 1973 to 2011 in North America, Europe, Australia, and New Zealand where sperm counts seems to have dropped by more than 50 percent. The study cannot show why sperm counts are declining. But the author of the study believes that various environmental factors, such as harmful chemicals, could be responsible for the steep decline in sperm counts, and worse yet, the drop doesn't seem to show any signs of slowing down. Because data from non-Western nations are either missing, not reliable or inadequate, the study couldn't show an equivalent decline in sperm counts from males in South America, Asia, and Sub-Saharan Africa. One could be tempted to think that this study shows how Western culture, lifestyle and industrialization exposes men to more harmful chemicals than typical lifestyles in the non-Western world, but again, this study is not capable of drawing such conclusions. What do you think is causing the steep decline in sperm counts? And is it just happening in the West or is it a global problem?
More bad news for our climate and future: in 2017, the oceans were by far the hottest ever recorded - and they are just getting warmer. The top five years on record in terms of ocean heat has all taken place since 2013. This increased heat in our oceans will result in rising sea levels and: We need to take drastic actions - now - to reduce our greenhouse gas emissions to avert the worst effects.
