Immigration is a european concern because immigrants: create negative population growth dilute european culture increase the threat of terrorism live on farms rebuild cities take employment away from "native" workers

Immigration is a European concern because immigrants:

European Countries have a low birth rate and the threat of migration influx increases a chance of culture dilution due to intermarriage and it also increases native population extinction. It is postulated that if the birth rate and the fertility rate continue to remain low, by 2300 Europe would have lost 95% of its population. For example, Italy has a fertility rate of 1.4% and only 1% will be left as the problem continues.

Another concern about immigration is the effects on the economy as the native feel immigrants threaten their jobs and welfare, especially on countries with lower incomes. Some countries have refused immigration and to host refugees due to fear of terrorism committed by non-residents.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
