For another example of how climate change is impacting ecosystems, check out this article from CNN, which details the impacts of warmer waters on fish populations. Using computer model simulations, researchers predict that by 2050, large numbers of marine organisms will migrate from warm, tropical waters to cooler regions of the ocean. Such a migration will cause a significant disruption in marine food chains, which could potentially lead to the extinction of many species that presently live in tropical waters. The movement of fish to cooler waters may also have a significant impact on human populations, especially in developing countries, where food shortages may become more frequent due to declining catches.
The Dominican Republic, located in the Caribbean, is particularly vulnerable to the impacts of climate change due to its geographic location and heavy dependence on agriculture, fisheries, and tourism. The country is also prone to natural disasters such as hurricanes and floods, which are becoming more frequent and
