In the US many plants that were native in one area are moving north as everything warms up. States are losing their state flowers, trees, etc. as the climate has changed enough to make it inhospitable for native plants and animals.
The Northwest Passage has completely thawed out in the last few years and there is no telling how this will affect animals, environment, etc. Plus if ships start traveling through the area there will be accidents, pollution and other issues.
Continuing pollution, greenhouse gases keep increasing temperatures, changing ozone levels, changing air quality effecting everyone on the planet. Many years ago airplane pilots could see for miles when flying, now there is a blanket of pollution around the whole planet and clear days have become rare.
This is our only world and we need to take care of it. We cannot be so arrogant to assume that everything will take care of itself and pass things on to the next generation. At some point we may reach a point where there is no reversal of what we have done.
