Scientists Issue Second Notice Letter to Humanity

Planet Earth as seen from space

Back in 1992, about 1,700 scientists from all over the world united their forces and issued a “warning to humanity” letter. In it, they were saying that the planet’s ecosystems had been pushed to the breaking point. The letter had an interesting way of listing those environmental dangers like they were some kind of biblical plagues. Among those dangers were air and water pollution, species loss, deforestation and finally, climate change.

However, they had no idea how bad things were going to become in the following years. This is why, to mark the 25th anniversary of that letter, over 15,000 scientists have issued a follow-up. On Monday, the journal BioScience published it. Once again, they are talking about the danger our planet is in. The experts are writing that over the past years, humanity has done nothing to stop or slow down those environmental threats. Because of this, things are getting worse than ever.

A new notice to humanity

William Ripple, an Oregon State University ecologist, is the leader of this second letter which, according to the authors, has the purpose to be a second “notice to humanity.” The most important global threat that the scientists are talking about in their letter is climate change. Since 1992, the global temperatures have increased with over half a degree Celsius. Moreover, the annual amount of carbon dioxide emissions has also increased by 62%.

However, this is not at all the only issue the planet is having. Fresh water is extremely scarce and wild-caught fish and the amount of forestland have also decreased. There are more dead zones in the oceans now. The balance is not straight, as the human population grew by 2 billion, while the animal population has decreased with about 30%.

The authors of the letter also offer some solutions for diminishing the impact those environmental dangers have on the planet. Among those are reducing food waste, green technologies and the establishment of nature reserves.
