There isn't much overlap between these two issues. Climate change is associated with using fossil fuels to produce energy. Decreases in biodiversity are associated with human land use such as agriculture, transportation, and construction, and also with pollution. Politically, tying one issue to the other just poisons them both. The only variable they share is the human population. Growth in human population is already slowing dramatically.
