Climate change means that some species of animals, even iconic ones like the polar bear, are going to become extinct. It also means that certain plant species are going to disappear. This is because the change in climate makes their habitats unable able to support them and unlike humans, they can’t just hop on a plane and fly somewhere that is more suitable for them.
Climate change means that poorer populations around the world, especially ones who live a long the coast, will lose their homes due to rising sea levels or suffer from the effects of extreme weather.
Climate change means that the world is going to become an increasingly unstable and unpredictable place for everyone. As climates change and food and water sources become affected, people may start fighting over the places that have these resources. I don’t know whether this will actually materialise, but more immediately, I think prices for basic resources will go up.
Climate change means that future generations will inherit an earth that is not as beautiful or hospitable as the one I grew up in or have had the fortune of experiencing.
