There are scientists who believe climate change is responsible for affecting every living species on earth. And they have launched research projects on several fronts. One that might at first seem unexpected is taking place in Costa Rica. It involves a species that is among the most feared on the planet – the venomous snake.

Each year over 100,000 people die from snake bites. Many of the victims are from underdeveloped countries. Costa Rica has developed an antivenom that could be a lifesaver for them.

Prevention measures from snakebites can be as simple as the use of proper footwear and access to basic tools for agriculture. Researchers say 50% of snake bites occur on feet and 30 % occur on bare hands when farmers work the land without tools. But getting those tools and the anti-venom medicine to some of the most underdeveloped regions in the world is a big challenge.
