Protecting Inventions while preserving biodiversityInvesting in biodiversity conservation and research is not just environmentally responsible—it's medically strategic, as each species lost represents the permanent erasure of unique biochemical compounds that could hold the key to treating current and future diseases. Understanding biodiversity also impacts diverse fields such as animal and plant breeding, agritech and public health.
