Seals and sea turtles on the verge of extinction

Global warming is not just causing polar bears to die, but seals as well. According to http://news.bbc.co.uk/2/hi/science/nature/4313726.stm" many seals are losing their habitats because of global warming. While many species are able to adapt to the new climate changes, and easily migrate to a different and secure location, this is a whole different concept for seals. The option of moving to conditions away from the poles doesn't go well with seals because they need the ice to stay alive. Many seals are actually drowning swimming large distances to find ice.

"Sea turtles are also being dramatically affected by global warming. Some of their precious beach nesting sites will disappear because of global warming. Scientists think that nearly a third of beaches used by turtles in the Caribbean could be lost during this century."states http://www.show.me.uk/site/news/STO903.html.
Warmer seas caused by global warming could make many turtles become entierly female during breeding. Why? well water temperature for sea turtles strongly affects the sex ratio of there hatch lings. Only producing female turtles, will of course make no more offspring because they cant produce on there own.
Another problem is global warming is striking these poor animals so rapidly that they don't have the time to adapt and evolve new strategies for survival. We can help by speaking out to the president becoming activists and giving donations to trusted companies that will preserve their habitat and maintain their life cycle.

Okay, after my first comment, I'm official tired now. So I'll just comment about the video of the bearded seal. That's incredibly heart-breaking, even given the fact that I couldn't care less about the seal in general; it's just plain sad. Perhaps they should advertise that video EVERYWHERE and people would realize the dramatic effects. Sooner or later, we will suffer a more horrific fate than those seals.
