The pretty existence of flourishing living methods – sea otters and kelp forests off the central California coast; salmon, orcas, and herring in Pacific Northwest waters; monk seals in the Mediterranean Sea – suggests which the ailments These organisms need to outlive are also existing.

The burning of fossil fuels is reworking the carbon cycle, mainly by boosting the atmospheric focus of carbon dioxide.
