Answer:
C. This has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction.
Step-by-step explanation:
Climate change has become an increasing threat to all species across the planet. The adverse effects of the changing climate are transferred to the ocean, where the temperature of the sea surface is increasing and rising sea level can change the marine ecosystem at many levels.
And sea turtles in one species that is affected much by this climate change. Since the sea turtles lays their eggs on the sand beach and spend rest of their lives in the ocean, climate change is affecting their life on both the sea and the ocean.
As given in the question that there is a rise in the sea level due to climatic change while there is an increase in the numbers of people moving into the coastal areas. To accommodate these people, there has been increased construction of beachfront resorts and condominiums. But this will lead to less availability of beach sand for the sea turtle for breeding and to lay eggs. Thus there is a decrease in the number of the these species.
