How does/will Global Warming affect the Earth?

There are so many ways global warming affects the Earth. Starting with the habitats, they are being altered and not all animals can adapt to it. The animals are losing places to live and food to eat. Some species, like fish and reptiles, gender depends on the temperature where they are born. Since the temperature is warming, they'll all be one gender, usually males. They won't be able to reproduce. As for the plants, they'll be fighting for the best places with the most water. If it gets this far, and let's hope it doesn't, humans won't have anything to eat. And there's a food shortage now! What will the future hold?
