Not yet all, but some authorities are waking up to the fact that we need to combat climate change. We have to comply with the Paris Agreement. Twelve governors committed themselves to Brazil’s goal of reducing greenhouse gas emissions by 37 percent – in relation to 2005 – by 2025. According to the Brazilian Forum on Climate Change, the representatives of 11 states, federal district also, are favorable to the theme. Now, it is important to keep an eye out to see if the promise is not just lip service.
It’s important to stress that the planet is heading for its sixth mass extinction, and the cause this time is not a meteor, like the one that decimated the dinosaurs, or some natural cataclysm: behind it is human activity. According to an alarming report released by the UN, out of the 8 million species of plants and animals that exist, from 500 thousand to 1 million are threatened to disappear. Unsustainable development commands destruction because it brings the inconsequential exploitation of soil and seas, climate change, pollution and invasive species – such as the Aedes aegypti mosquito itself, a plague that came from Egypt to torment the entire world.
But the damage goes a long way: since 1900, the average native species in most of Earth’s major biomes has declined by at least 20 percent, and at least 680 vertebrate species have become extinct since the 16th century. However, over the past 40 years the total number of endangered species has grown considerably: today, more than 40% of amphibian species, almost 33% of corals and 1/3 of marine mammals and sharks are threatened. “The extinction rate is hundreds of times greater than the natural rate,” says Paul Leadley, a professor at the Université Paris-Sud in Orsay and director of the Ecology, Systematics and Evolution laboratory.
