New wave of extinctions predicted for vital food species
May 31, 2017 07:14 AM - Emiliano Rodriguez Mega, SciDevNet

Poaching, illegal fishing and deforestation are threatening more than quarter of UNESCO’s World Heritage sites, according to a report by the WWF  (World Wide Fund for Nature) — and the consequences are not just environmental.

The report states that 18 out of the 50 threatened sites are in Latin American countries such as Argentina, Brazil, Colombia, Ecuador, Honduras, Panama and Peru. It also says the number could be higher because the illegal extraction of species in the region — a business with annual profits of almost US$ 2 billion — is not as well studied as it is in Africa or Asia.

Trump's wall puts wildlife at risk
February 9, 2017 07:10 AM - Lucina Melesio, SciDevNet

Building the wall that Donald Trump has ordered on January 25th, as one of his first actions as US president, will put on risk more than 50 animal species that share the ecosystem along the border between the United States and Mexico, scientists from various countries have warned.
Since 2006, 1,100 kilometers of barriers covering more than 30 per cent of the border between the countries have been built. The newest executive order commands the “immediate construction of a physical wall”, stating that ‘wall’ means “a physical barrier, continuous and impassable”.
