While of adapting to and withstanding a growing number

While some species may seem more important than others, in the grand scheme of things every species on this planet, no matter how small or charismatic has an important role to play. Preserving biodiversity is necessary for maintaining resilient ecosystems capable of adapting to and withstanding a growing number of stressors such as climate change and anthropogenic modification.  Healthy ecosystems rich in biodiversity provide a myriad of benefits that support human health and safety at little or no cost us. These benefits include (but a certainly not limited too) pollutant filtering, flood water attenuation, providing food, medical resources, protection and recovery from natural disasters, and suppling the raw materials for the goods and services we enjoy every day. While it can sometimes be difficult to assign a monetary value to the services provided by a healthy ecosystem, it seems obvious that having to replicate them (or even live without them)  would be difficult if not impossible and extremely expensive. While it is not always well understood how species interact or how they impact each other and their environment, we do know that a reduction in diversity within ecosystems can set off chain reactions and cause feedback cycles that have far reaching and sometimes poorly understood negative impacts that last well into the future and may be impossible to recover from. This lack of understanding as to how impacts to one species may affect others is why it is so important to protect biodiversity at all cost. When influencing policy on such a topic unfortunately what it often comes down to is human use value. So, while I personally feel it is important to preserve biodiversity for the enjoyment of future generations and simply for the love of the environment and/or species, beyond that it is a matter of public health and safety as well as economic stability. Our livelihoods are intertwined with the protection of the natural environments on which we rely.
