Climate change Nowdays, the topic of climate change is very popular, but it seems not everyone knows that it could threaten the future of mankind and all living beings. During the last 20 years, the temperature and the level of Co2 in the air is being increased. It is correlated to the increasing usage of carbon and other substancies not renawable. In december 2015 the pricipal nations in the world have achieved a remarkable agreement. All nations have signed this agreement, have to chase several individual targets. For instances, decreasing the usage of carbon and petrol and increasing the usage of renawable materials. On the other hand, a few months ago, we have officialy overtaked the maximum level of Co2. It means that we are not going to be able to come back under this safety level. As far as I know, it's not enough and things will get worse, unless all nations and all people will seriously strive together to reach this target. We have to stop taking this planet for granted. Thanks all
