While she does not advocate eliminating pesticides entirely, she suggests using them in more targeted ways. Check out Carson’s suggestions for alternative methods of pest control.
What are the main challenges in data science? How can mathematical models be dangerous? A mathematical model is a mathematical simulation of a real-world event. Three characteristics make them dangerous: they’re opaque, they don’t incorporate feedback, and they operate on a large scale.
